<h2 id="we-write-semantic-markup">We write semantic markup</h2>
<p>We avoid using <code>divs</code> and <code>spans</code> and try to choose more meaningful HTML elements instead. If unsure which element to use <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element" target="_blank">this list by MDN</a> can be of help.</p>
<p>Why?</p>
<ul>
<li>semantic markup is crucial for accessibility</li>
<li>it makes the code more readable for other developers</li>
<li>it benefits our SEO</li>
</ul>
<p>For more background <a href="https://css-tricks.com/why-how-and-when-to-use-semantic-html-and-aria/" target="_blank">see this article</a>.</p>
<p>This doesn&#x2019;t mean you can&#x2019;t ever use a <code>div</code> &#x2013; just think twice before you do!</p>
<h2 id="we-write-as-little-html-as-possible-&#x2013;-and-as-much-as-necessary">We write as little HTML as possible &#x2013; and as much as necessary</h2>
<p>HTML is used to <em>structure content on the page</em> and should therefore reflect its complexity. Not more and not less. Most content does not require deep nesting of HTML elements &#x2013; if you find yourself wrapping <code>container</code> around <code>container</code> or adding an element just to correctly position another element on the page this calls for the use of CSS instead!</p>
<p>Why?</p>
<ul>
<li>deep nesting makes it hard to understand, style and maintain components</li>
<li>it can lead to performance issues</li>
</ul>
<h2 id="recommended-reads">Recommended reads</h2>
