It isn’t anything mind-blowing, but I like the idea of placing bar graphs in a web page with <em>zero</em> Javascript.</p> -<p>So in the end, this is what our bar graphs will look like on desktop:</p> -<p>And this is how it will look on smaller devices:</p> -<p>Let’s get into the details!</p> -<h2 id="the-html">The HTML</h2> -<p>The main “secret” of this project is that our graphs are constructed out of HTML <em>tables</em>. Now before you freak out - this is perfectly fine and works in our favor quite well.</p> -<ol> -<li>If the user has JS disabled –> they will still see our graphs</li> -<li>If the user has CSS disabled –> they will see a standard data table set</li> -</ol> -<p>All bases are covered!</p> -<pre><code><!-- Using a basic table with our custom data-id --> -<table data-id="flexbox-bar-graph"> - <caption>Web Performance Results</caption> - <thead> - <tr> - <th>Test Performed</th> - <th>Before</th> - <th>After</th> - <th>Difference</th> - </tr> - </thead> - <tbody> - <tr> - <th>Initial Load Time</th> - <td> - <!-- - WTF are these CSS variables? - See the CSS section below - --> - <span style="--data-set:4.7/5;"></span> - <p>4.7</p> - </td> - <td> - <span style="--data-set:2.7/5;"></span> - <p>2.7</p> - </td> - <td> - <span style="--data-set:2/5;"></span> - <p>2</p> - </td> - </tr> - </tbody> -</table> -</code></pre> -<p>Nothing crazy is happening here - just your standard HTML table structure. The one main thing to notice is the <code>--data-set</code> CSS variable placed inline on each data point. This will be important for our CSS to configure the individual bar graphs properly.</p> -<h2 id="the-css">The CSS</h2> -<p>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:</p> -<ol> -<li>Baseline styling (mobile)</li> -<li>Desktop styling</li> -</ol> -<h3 id="baseline">Baseline</h3> -<p>Here we target just our table elements with the <code>data-id</code> of <code>flexbox-bar-graph</code>. This allows us to avoid worrying about adding classes or IDs and also avoids conflicts with other non-graph styled tables in our projects.</p> -<p>The base <code>:root</code> element holds all of our bar graph colors. Change these as you see fit!</p> -<pre><code>/* Bar Graph color variables */ -:root { - --bar-color-1: #357EC7; - --bar-color-2: #E42217; - --bar-color-3: #4CC417; - --bar-color-4: #7D0541; - --bar-color-5: #FFD801; -} - -[data-id="flexbox-bar-graph"] { - border-collapse: collapse; - margin: 4rem 0 6rem; - width: 100%; -} -[data-id="flexbox-bar-graph"] caption { - text-align: left; -} -[data-id="flexbox-bar-graph"] thead th { - text-align: right; -} -[data-id="flexbox-bar-graph"] thead th:nth-child(1), -[data-id="flexbox-bar-graph"] tbody th { - text-align: left; -} -[data-id="flexbox-bar-graph"] tbody th { - font-weight: normal; - font-style: italic; -} -[data-id="flexbox-bar-graph"] tbody td { - text-align: right; -} -[data-id="flexbox-bar-graph"] tbody td p { - margin: 0; -} -</code></pre> -<h3 id="desktop">Desktop</h3> -<p>Now we set your “visual” bar graphs to show at a set width (in this example it is 1000px and above).
