Alvaro Montoro<p>A really old joke coded in HTML and CSS using (some) trigonometry functions –yes, CSS has a few of those.</p><p>Source code and live demo at <a href="https://front-end.social/tags/CodePen" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CodePen</span></a>: <a href="https://codepen.io/alvaromontoro/pen/xbwZVLa" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">codepen.io/alvaromontoro/pen/x</span><span class="invisible">bwZVLa</span></a></p><p>Two TIL while coding this:</p><p>- You can add any Greek letter with HTML entities using their name (e.g., &theta;, &psi;...). Even capitalized versions. This may be common knowledge, I didn't know until today.</p><p>- The hypot() function in CSS. I knew other trigonometric functions, but not this one and it was helpful.</p><p><a href="https://front-end.social/tags/css" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>css</span></a> <a href="https://front-end.social/tags/cssart" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cssart</span></a></p>
