The History of Putting Things Side by Side

Why?

How to parse the tips and tricks
spanning 25 years of CSS features? 🤷‍♀️
 

When struggling with the options of flexbox, it's easy to say "this is impossible and too complex"
and not appreciate the long road to acquire them
 

We live in a golden age of layout design 🍕

Tables as Layout (CSS 2)

<center>
  <table>
    <tbody>
      <tr>
        <td class="item"><img src="first.png"></td>
        <td class="item"><img src="second.png"></td>
        <td class="item"><img src="third.png"></td>
      </tr>
    </tbody>
  </table>
</center>

199X to ~2006

table {
  border-collapse: collapse; /* Circa 2001 */
}

Tables as Layout

Tables as Layout

A lot of HTML, no CSS

Floats

Floats

Purple box has inline content that floats around floated content that precedes it.

 

Width restrictions or
clear: right;
places the second orange image onto a new row

clear: right;

Floats as Layout (CSS 2)

199X to ~2015

<div class="container">
  <div class="item"><img src="first.png"></div>
  <div class="item"><img src="second.png"></div>
  <div class="item"><img src="third.png"></div>
  <div class="clearfix" />
</div>
.item {
  float: left;
  width: 33.333333%;
}
.clearfix {
  clear: both;
}
/*
.container:after {
    content: '';
    display: block;
    clear: both;
}
*/

"Perfect"!

Uh oh...

JS + Absolute (Masonry, et. al.)

2007 to ~2014

<div class="container">
  <div class="item"><img src="first.png"></div>
  <div class="item"><img src="second.png"></div>
  <div class="item"><img src="third.png"></div>
  <div class="clearfix" />
</div>
.item {
  float: left;
  width: 33.333333%;
}
.clearfix {
  clear: both;
}
$('.container').masonry({
  itemSelector: '.item',
  columnWidth: 200
});

Fixed!?

Text

Masonry Downsides

  • One-trick pony for "cards"
  • Finicky
  • DOM style="" updates
  • JavaScript dependency
  • CSS / JS mismatches ⚠️
  • Requires knowledge of both CSS and JS

Masonry Upsides

  • Dynamic container, sorta responsive
  • Main way to accommodate 3-4 sizes in a grid
    (at the time)

Inline Block as Layout

2006 to ~2015

.item {
  display: inline-block;
  vertical-align: top;
  width: 33.333333%;
}
.container {
  word-spacing: -0.3em;
  /* or spacing hack of your choice */
}
<div class="container">
  <div class="item"><img src="first.png"></div>
  <div class="item"><img src="second.png"></div>
  <div class="item"><img src="third.png"></div>
</div>

Great!

Inline-block spacing woes

Wait what was that -0.3em?

White space = real space with inline block siblings

.container {
  font-size: 0;
  /* REM or PX Styleguide-dependent! */
}
.container {
  word-spacing: -0.28em; /* FONT! dependent */
}
<div>...</div><div>...</div>
<!-- no space - no problem! -->

Flex Layout

2014-

.container {
  display: flex;
  flex-wrap: wrap;
}
.item {
  width: 33.333333%;
  /* or flex: 1 0; */
}
<div class="container">
  <div class="item"><img src="first.png"></div>
  <div class="item"><img src="second.png"></div>
  <div class="item"><img src="third.png"></div>
</div>

"You want it, you got it!"

You want that?...

you got it!

(shoutout to inline-flex)

Grid Layout

.container {
  grid-template-columns: 33.33333% 33.33333% 33.33333%;
}
.item {}

2018-

Watch this space!

Columns Property

p {
  columns: 12em auto;
}
<p>Lorem ipsum...</p>

2012-

Columns property is useful

... but not for page layout.

Surprise

HTML align property

(big 👎 on MDN)

https://www.w3schools.com/tags/att_div_align.asp

HTML align property

<img align="left" src="first.png">
<img align="right" src="third.png">
<table width="200" align="left">
  <tbody>
    <tr>
      <td class="item"><img src="first.png"></td>
    </tr>
  </tbody>
</table>
<table width="200" align="right">
  <tbody>
    <tr>
      <td class="item"><img src="third.png"></td>
    </tr>
  </tbody>
</table>

HTML align property

<img align="left" src="first.png">
<img align="right" src="second.png">
<table width="200" align="left">
  <tbody>
    <tr>
      <td class="item"><img src="first.png"></td>
    </tr>
  </tbody>
</table>
<table width="200" align="right">
  <tbody>
    <tr>
      <td class="item"><img src="second.png"></td>
    </tr>
  </tbody>
</table>

HTML align property

- Can be used for side-by-side layout
- Nothing to do with "text alignment", float!
- Doesn't get stripped out by email applications
   when placed on tables
- Works in the oldest Outlook email browsers
   to this day
- Behavior be overriden in modern browsers
   using "float: none" and so on

The golden age of layout

With IE10 sunset, 2020-1-24...
flex is now supported by all browsers!

 

With IE11 sunset, 2025-10-14...

grid will be supported by all browsers!
