GRID SYSTEM

How does it work?

CONTAINER

Always start with a container

ROWS

then insert rows

ROWS

then insert rows

ROWS

more rows

HOW DO WE FILL ROWS?

COLS

The elementary block

DEVICE SIZEs

xs - Extra small devices (Phones < 768px)
sm - Small devices (Tablets > 768px)
md - Medium devices (Larger than 992px)
lg - Large devices (Desktops > 1200px)

example - 2 cols

<div class=“container”>
  <div class=“row”>

    <div class=“col-xs-6”></div>
    <div class=“col-xs-6”></div>

  </div>
</div>

Mobile first means that .col-xs-6 will apply to larger screens

WHAT HAPPENS?

<div class=“container”>
  <div class=“row”>

    <div class=“col-xs-6”></div>
    <div class=“col-xs-6”></div>
    <div class=“col-xs-6”></div>

  </div>
</div>

RESPONSIVE EXAMPLE

<div class="container">
  <div class="row">
    <div class="col-xs-6 col-sm-3"></div>
    <div class="col-xs-6 col-sm-3"></div>
    <div class="col-xs-6 col-sm-3"></div>
    <div class="col-xs-6 col-sm-3"></div>
  </div>
</div>

YOUR turn

Start with a raw initial grid

Insert each feature in a col

<div class="col-xs-6 col-sm-3">
  <div class="feature">
    ...
  </div>
</div>

<div class="container">
  <div class="row">
    <div class="col-xs-6 col-sm-3"></div>
    <div class="col-xs-6 col-sm-3"></div>
    <div class="col-xs-6 col-sm-3"></div>
    <div class="col-xs-6 col-sm-3"></div>
  </div>
</div>

Javascript

JavaScript is a powerful dynamic language.

It can be used to animate or change your HTML content
All without reloading your page!

JQUERY

jQuery is a powerful and popular JavaScript library

Installed on 65% of top 10 million web pages

It's designed to make your life easy

THE $() FUNCTION

Selects all divs on your page

$( "div" )

Selects all tags with a "hello" class on your page

$( ".hello" )

Finds the element with the "wagon" id on your page

$( "#wagon" )

Any CSS Selector will do

$( "#footer>a>li" )

Some Jquery functions

Makes your #footer disappear

$( '#footer' ).hide()

Makes your #footer reappear

Makes your #header appear gradually

$( '#header' ).fadeIn()

Selects all divs on your page

$( '#footer' ).show()

$( '#header' ).fadeOut()

YOUR TURN

Create an application.js file in your folder
Add this line at the bottom of your body:

<script src="application.js"></script>

YOUR TURN - Javascript

$(document).ready(function() {
  // Your code here
});

YOUR TURN - BODY

Add a div with "main-title" id on

your h1, tagline and button

<div id="main-title">
  <h1>The Best Page Ever</h1>
  <p> Play with HTML and CSS!</p>
  <button class="btn btn-danger">Sign Up</button>
</div>

YOUR TURN - Javascript

$(document).ready(function() {
  $("#main-title").fadeIn(1000);
});

IT DOESN'T WORK!

SOLUTION IN THE CSS!

#main-title {
  display: none;
}

Thank you

See you soon !
