Introduction

Selectors

Simple Selector

The body is known as the simple selector and the background-color:#cccc99; is the property name and value

body {
    background-color:#cccc99;
}

id Selector

#myid {
    background-color:#cccc99;
}

class Selector

.myClass {
    font-style:italic;
}

You can group selector with a comma.

h1,h2 {
    background-color:#cccc99;
}

descendant selector

This will only effect the

elements below a div tag.

div p {
   background-color:#ddddaa;
}

child selector

This will only effect the child and not descendant

elements below a div tag.

div > p {
   background-color:#ddddaa;
}

<div>
  <form>
    <p>I'm a descendant but not a child</p>
  </form>
  <p>I'm a child</p>
</div>

attribute selector

This will only effect if the attribute matches.

img[alt=spacer] {
   padding:0px;
}

<img src="gradient.jpg" alt="spacer">

psuedo selector

This will only effect if the pseudo is true.

a:visited {color: #dddddd; }

other selectors

There are many other selectors. Here is an example.

ul: li:nth-child(3)
{
   background-color: #cccc99;
}

This sets the 3 child of the list to have background of #cccc99

Specifying CSS Property Values

keywords
- thing, thick, larger
Physical measurements
- inches (in), points (pt), picas(pc)
Screen measurements
- pixels
Relative measurements
- %, em
Color codes
- #rrggbb, rbg(r,g,b)
Fonts
- Helvetica, sans-serif
Functional notation
- rgb(r,g,b), url("http://test.com")

Cascading and Inheritance

Ordering rules

Rules last applied based on last read. I.E. in this case paragraphs will be Green

p 
{
  background-color:Gray;
}

p 
{
  background-color:Green;
}

Developer Tools

Chrome shows the user agent stylesheet as well as your stylesheet

CSS Reset Stylesheet

This can be used to reset to styles regardless of browser to reset.

Specificity

This is the number associated with the rule. The highest rule is the rule which is applied.

A Count of ID selectors
B Count of class and attribute selectors
C Count of type selectors

So

*                 /* a=0 b=0 c=0 -> specificity =     0  */
LI                /* a=0 b=0 c=1 -> specificity =     1  */  
UL LI             /* a=0 b=0 c=2 -> specificity =     2  */
LI.red            /* a=0 b=1 c=1 -> specificity =    11  */
#content          /* a=1 b=0 c=0 -> specificity =    100 */

Generally a more specific rule takes presidence. In devtools the styles appear in specificity order

Inheritance

Some properties are inherited when you use markup but some are not. Checkout [1] for details

CSS and the Box Model

The Big Three

Margin (distance from outside to border)
Border (border itself)
Padding (distance from border to inside)

Vertical Margins

The vertical margins collapse on top of each other to be the margin of one of the items. E.g. in a list if the list item margin is 5px, the distance between list items will be 5px not 5px for the top item bottom edge and 5px for the item below top edge.

Width

Width is the content size of the item and does not include the margins. Metrics within developer tools shows the calculation.

Display and Visibility

Display is generally block, inline, or none
- Block elements sit on top of each other
- Inline elements only move downward when there is not enough space
- Display of none removes an element along with the space

Visibility
- Hidden elements are not visible but reserves the space

Styling Text with CSS

Font Families

CSS defines five font categories

serif, e.g. Times New Roman
sans-serif e.g. Arial
cursive, e.g. Comic Sans
fantasy, e.g. Impact
monospace, e.g. Courier New

You use the font-family to specify this. You can specify a list of fonts and it will use the first match

p
{
  font-family:Arial, Helvetica, sans-serif
}

Font Sizes

You can use em which will scale the font from the default. 2em is 2 times the size of the default.

Positioning

Element Types

There are two types of elements, inline and block elements. Inline elements by default position along the line, block elements are stacked

Block Elements

 * <address>
 * <article>
 * <aside>
 * <blockquote>
 * <canvas>
 * <dd>
 * <div>
 * <dl>
 * <dt>
 * <fieldset>
 * <figcaption>
 * <figure>
 * <footer>
 * <form>
 * <h1>-<h6>
 * <header>
 * <hr>
 * <li>
 * <main>
 * <nav>
 * <noscript>
 * <ol>
 * <p>
 * <pre>
 * <section>
 * <table>
 * <tfoot>
 * <ul>
 * <video>

Inline Elements

 * <a>
 * <abbr>
 * <acronym>
 * <b>
 * <bdo>
 * <big>
 * <br>
 * <button>
 * <cite>
 * <code>
 * <dfn>
 * <em>
 * <i>
 * <img>
 * <input>
 * <kbd>
 * <label>
 * <map>
 * <object>
 * <output>
 * <q>
 * <samp>
 * <script>
 * <select>
 * <small>
 * <span>
 * <strong>
 * <sub>
 * <sup>
 * <textarea>
 * <time>
 * <tt>
 * <var>

Relative Positioning

Relative positioning changes the position relatively from where the item would have been.

#buttons input:last-child
{
   position:relative
   top: 20px
   left: 50px
}

Fixed Positioning

Fixed positioning is when you specify the position and it remains in the same place relative to the document in the document when scrolled. Other items ignore fixed items'.

Absolute Positioning

Absolute positioning is when you specify the position and it remains in the same place regardless of when scrolled. Other items ignore absolute items.

Float and Clear

For inline elements float allows other elements to float up against the them. Clear stops this occurring

#figure1
{
   float:left
}

Z Index

The z index controls the order from front to back of the elements. i.e. a z-index as a negative pushes the element to the back. A positive index moves it to the front.

Bootstrep

Quick Stuff

p-x padding (padding all four)
m-x margin (padding all four)
rounded (rounded courners)

Layouts

Containers

Greats a centered squared on your web page. To take up all of the space you can use container-fluid.

Rows And Columns

Row and columns go inside of a container.

<div class="container"> 
    <div class="row">
        <div class="col">
        1 of 2
        </div>
        <div class="col">
        2 of 2
        </div>
    </div>
    <div class="row">
    </div>
</div>

There are 12 columns in a rows
You can use the offset class to leave a gap of a given size between the rows

    <div class="row">
        <div class="col-md-2">
        1 of 2
        </div>
        <div class="col-md-4 offset-md-6">
        2 of 2
        </div>
    </div>

Breakpoints

These are the breakpoints
Using the lg (large) we use 4 columns for the logo and 8 for the text. Using sm (small) we reverse this

<div class="row">
    <img src="images/products/applepie.jpg" class="col-lg-4 col-sm-8" />
    <div cla ss="col-lg-8 col-sm-4">
        <h2>Bethany's Pie Shop</h2>
        <h3>Welcome to our store</h3>
        <p>Sweet ice cream jelly beans lemon drops. Pastry toffee fruitcake gingerbread jelly-o.Lollipop sesame snaps muffin. Macaroon halvah marshmallow sesame snaps sugar plum dragée. Wafer pudding sesame snaps tootsie roll sesame snaps cake chupa chups jelly beans.
        </p>
    </div>
</div>

Large

Small

Styles

Text

We can improve text with

display-n-4, e.g. display-1,display-2

We can align text with

text-center
text-left
text-right
text-justify

All of the break points can be used, e.g. text-sm-left

Images

We can improve images with

rounded
img-fluid (resizes the image to the container)

Tables

Interesting table classes are

table-striped
table-hover
table-bordered
table-responsive (adds scrollbar to table errr)

Layout

Directional Application

The following can be used with the padding and margins

l left
r right
t top
b bottom
x left and right
y top and bottom

Margins and Padding

To apply margins and padding in bootstrap

Margins using the m-1 for all or mt-1 for top, mb-1 for bottom, mx-1 for x
Padding using the p-1 for all or pt-1 for top, pb-1 for bottom, py-1 for y

Components

Nav Bar

The nav bar is put in the header tag before the main tag. The fixed-top ensures it remains at the top of the page.

<body>
    <header>
        <nav class="navbar navbar-expand-sm navbar-dark fixed-top bg-dark">
            <div class="container">
...
            </div>
        </nav>
    </header>
    <main role="main">
    </main>
</body>

Modals

We add data-toggle and data-target on html element to create the dialog.

<a type="button" data-toggle="modal" data-target="#IdOfTheModal">Add</a>

For the modal we need to set the role to dialog and class to modal fade. Examples are available on the bootstrap site. The data-dismiss="modal" can be specified on a button to close the dialog.

<div class="modal fade" tabindex="-1" id="IdOfTheModal">
   <div class="modal-dialog">
       <div class="modal-content">
           <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
       </div>
   </div>
</div>

Flexbox

Another Approach

Have great trouble with flexbox (probably dyslexia) so took another approach.

<html>

<head>
    <link rel="stylesheet" href="test.css">
</head>

<body>
    <div>ROW</div>
    <div class="row">
        <div class="item">This</div>
        <div class="item">Is </div>
        <div class="item">how</div>
        <div class="item">to</div>
        <div class="item">a</div>
        <div class="item">row</div>

    <div class="container-flex-shrink">
        <div class="row">

            <div class="item">Is </div>
            <div class="item">how</div>
            <div class="item">to</div>
            <div class="item">a</div>
            <div class="item">row</div>

    </div>
    </br>
    <div>Shrink ROW Centered</div>
    <div class="container-flex-shrink-centered">
        <div class="row">
            <div class="item">This</div>
            <div class="item">Is </div>
            <div class="item">how</div>
            <div class="item">to</div>
            <div class="item">a</div>

            <div class="item">column</div>
        </div>
    </div>
    </br>

</body>

</html>

And the CSS

.col {
    display: flex;
    flex-direction: column;
    background-color: green;
}

.row {
    display: flex;
    flex-direction: row;
    background-color: blue;
}

.row-centered {
    justify-content: center;
}

.col-centered {
    align-items: center;
}

.table {
    background-color: aqua;
    padding: 1vw;
}

.row-header {
    display: flex;
    flex-direction: row;
    background-color: purple;
}


.item-header {
    margin: 2px;
    width: 3vw;
    background-color: red;
}
.item {
    margin: 2px;
    width: 3vw;
    background-color: orange;
}

.container-flex-shrink {
    display: flex;
}

.container-flex-shrink-centered {
    display: flex;
    justify-content: center;
}

Rows and Columns

Introduction

In bootstrap we saw the way to do this was

<div class="container"> 
    <div class="row">
        <div class="col">
        1 of 2
        </div>
        <div class="col">
        2 of 2
        </div>
    </div>
    <div class="row">
    </div>
</div>

And that there was a magic number of 12. With flexbox there is no magic number and we can have as many as we like.

	<div class="d-flex flex-row" style="background-color: yellow;">
		<div style="background-color: green;" class="col">New Test 1 of 2</div>
		<div style="background-color: orange;" class="col">New Test 2 of 2</div>
	</div>

We can stack the boxes horizontally. We add the d-block class to denote that it is a block element i.e. it cannot have elements wrapped on to it.

	<div class="d-flex flex-row" style="background-color: purple;">

		<div class="d-flex flex-column" style="background-color: green;">
				<img src="images/mountain_Blue.png" class="d-block">
				<h3>Climbing</h3>
				<p>I love this</h3>
		</div>

		<div class="d-flex flex-column" style="background-color: green;">
			<img src="images/mountain_Blue.png" class="d-block">
			<h3>Climbing</h3>
			<p>I love this</h3>
		</div>

		<div class="d-flex flex-column" style="background-color: green;">
			<img src="images/mountain_Blue.png" class="d-block">
			<h3>Climbing</h3>
			<p>I love this</h3>
		</div>
	</div>

In the tutorial they used css to define the bootstrap sizes by simple creating classes and applying them to the html

.w-60{
	width: 60%!important;
}

.h-30{
	width: 30%!important;
}

.w-20{
	width: 20%!important;
}

Main Axis and Cross Axis

When looking at the documentation and you see main or cross you need to take into account whether you are dealing with columns or rows.

Alignment And Layout

Alignment

The self refers to item within a group. So given the html

	<div class="d-flex flex-row testRow">
		<div class="testBox">Test 1</div>
		<div class="testBox align-self-center">Test 2</div>
		<div class="testBox">Test 3</div>
	</div>

The text box is aligned within the row of items.

Grow Shrink Fill

The flex-grow, flex-fill and flex-shrink allow the row components change size

	<div class="d-flex flex-row testRow">
		<div class="testBox">Test 1</div>
		<div class="testBox">Test 2</div>
		<div class="testBox flex-fill">Flex Fill</div>
	</div>

	<div class="d-flex flex-row testRow">
		<div class="testBox">Test 1</div>
		<div class="testBox flex-grow-1">Flex Grow</div>
	</div>

Auto Margins

We use auto margins to push out other controls based on the directional suffix

	<div class="d-flex flex-row testRow">
		<div class="testBox">Test 1</div>
		<div class="testBox ml-auto">Test 2</div>
		<div class="testBox">Test 3</div>
	</div>

Breakpoints

The breakpoints can now be added to the css use the media query.

.banner{
	height: 150px;
	background-image: url('../images/shutterstock_116403520.jpg');
	background-size: cover;
	background-position: center -100px;
}

@media (min-width: 576px) {
	.banner{
		height: 200px;
	}
}

/*Medium devices (tablets, 768px and up)*/
@media (min-width: 768px) {
	.banner{
		height: 300px;
	}
}

/*Large devices (desktops, 992px and up)*/
@media (min-width: 992px) {
	.banner{
		height: 400px;
	}
}

/*Extra large devices (large desktops, 1200px and up)*/
@media (min-width: 1200px) {

}

CSS Transitions

Introduction

Transitions need two elements property and duration. http://codepen.io is a excellent site to practice.

transition-property the property you want to transition. Not all things are transitionable. ggo.gl/Ttk1S2
transition-duration in seconds or milliseconds
transition-time-function for the transition optional
transition-delay how long to delay the transition

Kicking a Ball

Details were at http://cdpn.io/fGFDj

.paw {
  transition: transform .25s ease-in;
}

.playing .paw {
  transform: translateX(30px);
}

.paw {
  position: absolute; top: 0; left: 80px;
}

.ball {
  background: #0097C0;
  border-radius: 50%;
  position: absolute; top: 200px; left: 160px;
  width: 100px; height: 100px;
}

body { background: #e3edf2; }

And the HTML

<!--HTML: Use these classes for reference!-->
<div class="ball"></div>
<img class="paw" src="https://s3.amazonaws.com/stash.rachelnabors.com/codepen/css-animation-workshop/paw.png" />

And the JavaScript

$(window).on('load', function(){
  $("body").addClass("playing");
});

Multiple Properties

Crappy format

transition-property: color, transform
transition-duration: 2s, 300ms
transition-delay: 0, 1s

Good format

transition:
  color 2s,
  transform 300ms 1s

Duration Of Animations

Recommended sweet spot is 250-300ms - Not much more to say, 1 second is the top end.

Easing

Timing Functions
- ease-out
- ease-in
- ease-in-out
- linear
- cubic-bezier

See http://cubic-bezier.com is a good site to make these.

transition-timing-function: ease-in 
// Or
transition-timing-function: cubic-bezier(0.445, 0.05, 0.55, 0.95)

CSS Animations

Introduction

animation-name the name of the keyframe block you want to use
animation-duration how long the animations takes to go from 0% to 100%
animation-iteration-count the number of times you want to go from 0% to 100%; use infinite to never stop. Default to 1
animation-timing-function like transition-timing-function
animation-delay like transition-delay
animation-fill-mode can be backwards or forwards, both or none

.animated-thing {
 animation: black-to-white 1s linear 1
}

@keyframes black-to-white {
  0% { background: #000; }
  100% { background: #fff; }
}

/* Or in full */
.animated-thing {
   animation: 
     $name
     $duration
     $timing-function
     $animation-delay
     $iteration-count
}

Making a Walk-Cycle

Nice intro to this and code at cdpn.io/cdqga

<div class="tuna"></div>

<p>You can do it!</p>

And the JS

.tuna {

Animation Design

Liked this.

Jump cuts when you move from on state to another without a transition. E.g. In the movies with no fade out/fade in
In betweening this is the things you put between frames to perform a transition. E.g. in cartoons drawing the movements between step 1 and step 2

Sensing Visual Play Readdiness

Nice example on this at http://cdpn.io/JDcwI

<!-- swap the .loading class with .loaded using JavaScript, manipulate visibility with CSS -->

<div id="stage" class="loading">
  <div class="loader">
    <div class="rollout">
      <img src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/641/yarnball.svg" class="yarn" />
    </div>
    <div class="loading-text">Loading</div>
  </div>
  <div class="scene window">
    <div class="tail"></div>
  </div>
</div>

And the JS

$(window).load(function(){
  setTimeout(function(){
      // use .addClass() and .removeClass() to swap the loading class for loaded on #stage.
    }, 6000);
});

And the CSS

/* Set transitions on both .loader and .scene */
.loader, .scene {
}

/* See how their opacity is 0 when loaded or loading? No more CSS edits needed below. */
.loaded .loader, .loading .scene {
  opacity: 0;
}

/* Loader CSS */
.loader {
  position: absolute;
  width: 100%; 
  top: 50%;
  transform: translateY(-50%);
}

.loading-text { font-size: 3em; }

.rollout {

	background-size:400px 24px;

	position: absolute; left: 50%; margin-left: -200px;
	animation: unrolling-strand 6s cubic-bezier(.57,.27,.46,.79) infinite forwards;
	width: 0;
}

@keyframes unrolling-strand {
	60% {
		opacity: 1;
		width: 400px;
	}
	70% {
		opacity: 0;
		width: 400px;
	}
	100% {
		opacity: 0;
		width: 400px;
	}
}

.loading-text {
	animation: loading-fadein 6s cubic-bezier(.57,.27,.46,.79) infinite forwards;
	opacity: 0;
	text-align: center;
}

@keyframes loading-fadein {
	65% { opacity: 0; }
	82.5% { opacity: 1; }
	100% { opacity: 0; }
}

.yarn {
  animation: rolling-yarn 6s cubic-bezier(.57,.27,.46,.79) infinite forwards;
  position: absolute;
  right: -20px; top: 0;
  width: 40px;
}

@keyframes rolling-yarn {
  60% { transform: rotate(1146deg); }
  100% { transform: rotate(1146deg); }
} 

/* Window CSS */
.window {
  background: url("https://s3-us-west-2.amazonaws.com/s.cdpn.io/641/tuna-window.png") no-repeat 0 0;
  background-size: 100% auto;

}

body {

Will-change

This usuage of CSS moved work to the GPU and should not be used

.resource-sink {
   transform: translateZ(0);
}

We can not use
.in-view .animated-thing {
   will-change:transform
}

.inview .animated-thing:hover {
   transform: translateY(5%)
}

DevTools

Stuff

In the console you can enter javascript so modify the DOM. Note the DOM is not the source. e.g.

document.body.appendChild(document.createElement('h3'));
document.querySelector('h3').innerText = "Testing";

Search

use Inspect
ctrl+f in devtools
use point top left of devtools

Colors

Orange is margin
Green is padding

Styles

The Styles pane shows the styles cascading from bottom (defaults) to the top (latest)
The Computed pane shows just what has been applied for an element
The format button on the bottom on devtools (not shown) lets you unminify style sheets
The element states can be set using the :hov next to the filter button
The element.style box allows you to enter a style for the current element

You can dynamically change the margins, padding border by double-clicking

JavaScript Console

console.dir Json format
console.table for table format
console.assert e.g. console.assert(data.length === 15, {'stuff':'tooutput'})
console.trace()

To output to the console with a label and not expanded

 
console.groupCollapsed(`my stuff`)
console.log('many lines 1')
console.log('many lines 1000')
console.groupEnd()

Devtools Console

Introduction

You can add functions to objects selected in the Elements tab in the devtools console. $0 to $4 in the console will show which object is assigned to which variable. For example

function logEvent(event) {
  console.log(`An event occurred: ${event.type}`)
}

$0.addEventListener(`click`, logEvent);

Monitor and Debug

Monitor can be used to get console alert when a function executed. For example

monitor(logEvent);

debug(logEvent) stops the code on the first line of function

Live Expressions

These can be created in the console and will be pinned to the top of the console so you can monitor values changing.

Debbugger

Log Points allow output of variables to the console. Right-client and type 'stuff', myvar and it will log to the console
