<table>

Layouts are basically a mess

{ float : right }

{ position : absolute }

{ display : table }

@mjordancodes

How can we handle all these devices and avoid div soup?

@mjordancodes

{ display: flex }

The Flexible Box Module, usually referred to as flexbox, was designed as a one-dimensional layout model, and as a method that could offer space distribution between items in an interface and powerful alignment capabilities.

Let's Try It!

Flexbox NavBar

@mjordancodes

<nav>  
  <span class="menu-toggle">Menu</span>
  <div class="menu-content">
    <a href="#">Home</a>
    <a href="#">About</a>
    <a href="#">Portfolio</a>
    <a href="#">Blog</a>
    <a href="#">Contact</a>
  </div>
</nav>

Some simple HTML to start...

@mjordancodes

body {
  margin: 0;
  padding: 0;
}

.menu-toggle {
  padding: 10px;
  display: block;
  text-align: center;
  cursor: pointer;
  background: #BEDB39;
}

CSS to start things off

@mjordancodes

.menu-content {
  display: flex;
  flex-direction: column;
  align-items: center;
}

Starting to Flex the things

@mjordancodes

.menu-content {
  display: flex;
  flex-direction: column;
  align-items: center;
}

.menu-content a {
  padding: 5px 0;
  background: #004358;
  width: 100%;
  text-align: center;
  color: #fff;
  text-decoration: none;
}

nav:hover .menu-content a:hover {
  background: #1F8A70;
}

And a little bit of pretty hovers

none;

nav:hover .menu-content {
  display: flex;
}

@mjordancodes

@media screen and (min-width: 400px) {
  .menu-toggle {
    display: none;
  }
  .menu-content {
    display: flex;
    flex-direction: row;
  }
  .menu-content a {
    padding: 10px 0;
  }
}

{ display: grid }

CSS Grid Layout excels at dividing a page into major regions or defining the relationship in terms of size, position, and layer, between parts of a control built from HTML primitives. Grid is for working in two-dimensions.
