Now before you freak out - this is perfectly fine and works in our favor quite well. - -1. If the user has JS disabled --> they will still see our graphs -2. If the user has CSS disabled --> they will see a standard data table set - -All bases are covered! - - - - - - - - - - - - - - - - - - - - - -

- - -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. - -## The CSS - -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: - -1. Baseline styling (mobile) -2. Desktop styling - -### Baseline - -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.

- -The change in CSS is actually quite simple to pull this off - you just need to include the `data-layout` attribute on the table itself. - - - [data-layout="horizontal"] tbody { - min-height: auto; - } - - [data-layout="horizontal"] tbody tr { - flex-direction: column; - padding: 0 40px; - } - [data-layout="horizontal"] tbody tr th { - width: calc(100% - 80px); - } - - [data-layout="horizontal"] tbody tr th { - text-align: left; - top: calc(100% + 20px); - } - - [data-layout="horizontal"] tbody tr td { - flex-direction: row; - height: auto; - justify-content: start; - margin: 10px 0; - } - - [data-layout="horizontal"] tbody tr td span { - height: 20px; - width: calc(var(--data-set) * 100%); - } - - [data-layout="horizontal"] tbody tr td p { - margin-left: 10px; - } - - -## That's All Folks! - -That just about sums things up.
