    <h1>Cleaner CSS</h1>
  </section>

  <p>This website is nothing more than a set of small demos for the idea of
    using flexbox and grids to clean up and simplify CSS. Most everything else
    about CSS stays.  Filters, transforms, attributes, and everything that
    applies to the visual display of the components of a design.  What gets
    removed is <b>div</b> heavy, class heavy, not-semantic-at-all layout
    systems cluttering the real information available through simple HTML
    tags.</p>

  <p>In short, if you're writing this:</p>

  <section>
  <aside>
  <pre>
&lt;div class="grid col-1">
  &lt;div class="card">
  ...
  &lt;/div>
&lt;/div>
  </pre>
  </aside>
  </section>

  <p>You could write this if you use flexbox, grids, and variables:</p>

  <section>
  <aside>
  <pre>
&lt;card>
  ...
&lt;/card>
  </pre>
  </aside>
  </section>

  <h1>What's wrong with classes?</h1>

  <p>There's nothing wrong with classes in CSS. How they're used in recent CSS subverts the normal specificity rules making CSS unecessarily difficult.  The original specificity rules put the base design of a component at the tag level, then a <b>class</b> can be used to modify and extend the design, and an <b>id</b> can make this even more specific.  In today's use of <b>div.class</b> heavy markup you lose this ability to alter the design as needed where its used, and instead you have to resort to <b>!important</b> and specificity hacking to change how something looks, or add more <b>div</b> with more <b>class</b>.</p>

  <p>The other problem with <b>div.class</b> is it's more difficult to debug problems with the layout.  Because you're relying on specificity that can come from anywhere in the cascade it's much more difficult to find exactly <b>what</b> bit of CSS is overriding your local decisions.  If you've ever had to open the inspector in your browser to troll through CSS locations looking for the culprit then that's why.  If the base design decisions are at the tag level, then your local <b>class</b> and <b>id</b> specifics will work as expected.  You can also replace many uses of class as design modifiers with scoped CSS variables and reduce the use of <b>div.class</b> even further.</p>

  <p>Finally, using <b>div.class</b> heavy layout systems polutes your markup with structure that's difficult to maintain and change over time.  When you focus on using <b>truly</b> semantic named tags and follow specificity as intended then your HTML is lighter and easier to understand because it isn't full of <b>div.grid.col-1.col-mx-auto</b> class rules that really have nothing to do with the actual meaning of that particular visual element.  With <b>flexbox</b> and <b>CSS grids</b> you don't need any layout divs, and can keep the HTML clean and semantic.  This also ends up being more flexible with less or the same effort as using a pre-made grid system full of divs.</p>

  <h1>Should we ban div.class?</h1>

  <p>Hell no.  The current problem of <b>too much</b> class based CSS is because of trends in recent years calling for everyone to irrationally ban some practice.  Remember when everyone decided tables were evil?  So then we banned tables and <b>grids</b> completely?  Then nobody could do a layout without crazy tricks and JavaScript?  Nobody wants a repeat of the anti-tables "semantic markup" war, so please don't ban div.class.</p>

  <p>All this website does is demonstrate that you don't need <b>so much div.class</b>.  You can scrap a lot of what you're using now to do layout and go with clean easy to read HTML that has a nicer flat structure and is easy to maintain, then judiciously add in any extra things you find you need like <b>div.class</b>.  Treat <b>div.class</b> like salt. Right now you're pouring a whole box of it on your HTML when a little bit makes it taste better.</p>

  <h1>How did it get like this?</h1>
  <p>Before flexbox and CSS grids there really was no choice but to use <b>div.class</b> to make grids for layout.  Since everyone in the CSS design world irrationally banned tables as a layout mechanism your only choice was to invent another table but call it <b>div.grid.col-1</b>.</p>

  <p>Today we don't have to use divs for layout anymore.  It's entirely possible to use flexbox and CSS grids to solve many layout problems, and to do it without too many irrelevant alterations to the meaningful HTML. You no longer have to wrap an <b>img</b> with 5 <b>div</b> tags just to overlay it on a background. You can write the <b>img</b>, maybe a <b>figure</b> and then use CSS to do anything you want to it.</p>
