<h1>Resetting links</h1>

<h2>The problem</h2>

<p>(link as parent with green border / div as child with red border)</p>

<!-- example of the default -->
<a class='default-link' href='#'>
  <div class='block'>
    block-level element in a default link
  </div>
</a>

<p>^ problem revealed! (inspect)</p>

<p><a href='https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a' target='mdn/a'>Links</a> are <code>display: inline;</code> by default. That means they aren't cut out for containing <em>block-level</em> elements. That's just not their specialty.</p>

<p>That was fine for the 90s, but these days links are use in many more places than runs of paragraph text.</p>

<p>There are probably more links <em>wrapped around images</em> and various other components than there are regular ol links now. So, it makes sense to reset them to block elements as a default. Then you can replace the regular link styles in paragraphs specifically.</p>

<h2>With the reset</h2>

<a href='#' class='product'>
  <img src='https://peprojects.dev/images/square.jpg' width='400'>
</a>

<p>Example paragraph with <a href='#'>a link</a> in it.</p>
