Pure CSS Bar Graphs with Graceful Mobile Fallbacks

I recently published a new open source project, Flexbox Bar Graphs, and wanted to share a simple breakdown of how it was built. It isn't anything mind-blowing, but I like the idea of placing bar graphs in a web page with zero Javascript.

I recently published a new open source project, Flexbox Bar Graphs, and wanted to share a simple breakdown of how it was built. It isn’t anything mind-blowing, but I like the idea of placing bar graphs in a web page with zero Javascript.

So in the end, this is what our bar graphs will look like on desktop:

-

- Flexbox Bar Graph -
The flexbox bar graph in desktop view (direct link to image)
-

+

And this is how it will look on smaller devices:

-

- Flexbox Bar Graph Table -
The flexbox bar graph on mobile devices (direct link to image)
-

-

Let's get into the details!

-

The HTML

-

The main "secret" of this project is that our graphs are constructed out of HTML tables. Now before you freak out - this is perfectly fine and works in our favor quite well.

Nothing crazy is happening here - just your standard HTML table structure. The one main thing to notice is the --data-set CSS variable placed inline on each data point. This will be important for our CSS to configure the individual bar graphs properly.

This might look overwhelming if I just dumped the whole CSS file in one big code block, so instead I'm going to break them down into two parts:

Here we target just our table elements with the data-id of flexbox-bar-graph. This allows us to avoid worrying about adding classes or IDs and also avoids conflicts with other non-graph styled tables in our projects.

The base :root element holds all of our bar graph colors. Change these as you see fit!

Now we set your "visual" bar graphs to show at a set width (in this example it is 1000px and above). That way the "default" styling can target the mobile device screen sizes.
