Can I Use CSSGrid?

Good idea to start using CSS Grids I think

Mikel: 3/02/18

What is CSSGrid for?

Features:

  • Very precise layout
  • No extra divs
  • One line responsiveness
.header {
  display: grid;
  grid-template-columns: repeat(3, 33%);
  grid-template-areas: 
    "empty logo nav";
}
.logo {
  grid-area: logo;
}
.nav {
  grid-area: nav;
}

Repeat replaces

33% 33% 33%

<header class="header>
  <a href="#" class="logo">
    <img src="logo.png">
  </a>
  <nav class="nav">
    <a href="#">Dashboard</a>
    <a href="#">Profile</a>
    <a href="#">Sign Out</a>
    <img src="avatar">
  </nav>
</header>
.two_columns {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-gap: 5px;
}

fr = "fraction"

.two_columns {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-gap: 10px;
  @include mobile {
    grid-template-columns: 1fr;
  }
}
@mixin mobile {
  @media only screen and (max-width: 768px) {
    @content;
  }
}

Helper mixin for inline mobile styling

SCSS Mobile Mixins

@mixin grid(cols) {
  display: grid;
  grid-template-columns: repeat(cols, 1fr);
  @include mobile {
    grid-template-columns: 1fr;
  }
}

Helper mixin for grids

.content {
  @include grid(2);
}

Double mixin!

.three_columns {
  display: grid;
  grid-template-columns: 20% 60% 20%;
  @include mobile {
    grid-template-columns: 100%;
  }
}

Can do same with "rows"

.multi_columns {
  display: grid;
  grid-template-columns: 
    repeat(auto-fit, minmax(350px, 1fr));
}

Use with caution

Advanced!

One line responsiveness

Can I Use Flexbox?

Flexbox prefixes

gem "autoprefixer-rails"

There's a Gem for that!

What is Flexbox for?

Features:

  • Better browser support
  • Vertical centering!
  • Handles alignment for you
.login_page {
  display: flex;
  align-items: center;
  justify-content: center;
  min-height: 100vh;
}

Centering!

align-items: vertical

justify-content: horizontal

.nav {
  display: flex;
  align-items: center;
  justify-content: flex-end;
}

Aligning!

.nav {
  display: flex;
  align-items: center;
  justify-content: flex-end;
  @include mobile {
    flex-direction: column;
  }
}

Mobile view?

Row by default

Can I Use Columns?

What is Columns for?

Features:

  • Masonry Layout
    • No white gaps
  • Handles ordering for you
.list {
  column-count: 3;
  column-gap: 40px;
  @include mobile {
    column-count: 1;
  }
}

Masonary!

Grid

Flex box

But the client needs it to work in IE

Mixins to the Rescue!

@mixin grid {
  @supports (display: grid) {
    @content;
  }
}
.two_columns {
  // Fallback layout code

  @include grid {
    display: grid;
    grid-template-columns: 50% 50%;
  }
}

IE doesn't recognise supports

More mixins!

@mixin ie {
  @media screen and (min-width:0\0) {
    @content;
  }
}
.two_columns {
  display: grid;
  grid-template-columns: 50% 50%;
  @include ie {
    // fallback code
  }
}
