Multiple Columns in HTML5 and CSS3

Creating a multiple column pages is so much easier now with HTML5 and CSS3 than was previously possible. Consider if you have a page with 200 unordered lists. The HTML markup for this would be something similar to this:

Unordered List

and so on….

As you’ve noticed, I’ve abbreviated the markup. The page rendered will be long. It will take some scrolling down to get to the bottom of the page. The obvious solution for this page layout is to display the data in multiple columns.

Displaying two to three columns is ideal. You can add more if you like. It really depends on how you want to layout your page. How do we add multiple columns on our pages? It’s quite easy. You’ll be surprised how simple it is.

First, let’s add a class div to our markup. In this example, we will call our div “data.” Our markup will now look like the example below. It’s relatively unchanged, except for the div we’ve just added.

HTML5 Markup

<div class=”data”>
and so on….

CSS3 Markup

The magic is really in CSS. It’s ideal to place a width in your class div, unless your class div is already inside another div that already has a width limit. We can then set a limit how wide we want our columns widths and column gaps.

I’m using a div with a width of 500px because it goes well with the 150px columns widths and 25px column gaps. You probably already guessed, the column widths are how wide the columns are, and the gaps are the spaces between column widths.

.data {
  -webkit-column-width:150px ;
  -moz-column-gap: 25px;
  -webkit-column-gap: 25px;

Give It A Try

Give it a try. Adding multiple columns in HTML5 and CSS3 is much easier than was previously thought. Create a simple page with some sample data. Add a class div and use the CSS3 multiple column styles to it.


The code has been tested with Mozilla Firefox, Google Chrome and Apple’s Safari. I haven’t tested it with any Internet Explorer. I’ll be curious if it works with IE 7, 8 or 9.

Here’s a demo of a page using the multiple columns.

HTML5 Boilerplate

If you’re looking for a rock-solid HTML5 template, check out the HTML5 Boilerplate created by Paul Irish and Divya Manian. Here are more details from their site.

HTML5 Boilerplate is the professional badass’s base HTML/CSS/JS template for a fast, robust and future-proof site.

After more than two years in iterative development, you get the best of the best practices baked in: cross-browser normalization, performance optimizations, even optional features like cross-domain Ajax and Flash. A starter apache .htaccess config file hooks you the eff up with caching rules and preps your site to serve HTML5 video, use @font-face, and get your gzip zipple on.

Boilerplate is not a framework, nor does it prescribe any philosophy of development, it’s just got some tricks to get your project off the ground quickly and right-footed.

A Great HTML5 Resource

There are hundreds of HTML5 resources on the Internet. One of my favorite is Dive Into HTML5. If you want an excellent introduction to HTML5, this is a good place to start. It’s written by Mark Pilgrim where he dissects all facets of HTML5 into ten chapters.

He starts out with a brief history of HTML, followed by how to detect HTML5, the details of the head elements, the markup, canvas, video, geolocation, local storage, offline applications and forms. The website also includes an Appendix of HTML5 elements.

This is an excellent read for those wanting to jump in and learn HTML5 quickly. If you want a hard copy, I recommend two books. One book is by Mark Pilgrim’s called, “HTML5: Up and Running.” The other is a book by Bruce Lawson and Remy Sharp’s called, “Introducing HTML5.”
