Varying navbar for mobile and desktop

Look at framer.com in various widths. The navbar is finely tuned based on the device width. As you decrease the device width, the logo moves above the text, then some links disappear (“Pricing”, “Trial”), then some links change their text (“Get Started” becomes “Start”), then the text gets smaller, then finally the links move to two rows.

How does the site achieve this? Using CSS classes like hide-laptop and hide-tablet-s:

<span class="hide-laptop">Get </span>Start<span class="hide-laptop">ed</span>
<li class="hide-tablet-s">
  <a href="/pricing" class="">Pricing</a>

These classes then have rules like:

@media screen and (max-width: 1024px) {
  .hide-laptop {
    display: none !important;

@media screen and (max-width: 600px) {
  .hide-tablet-s {
    display: none !important;

The CSS has many categories of device: desktop, laptop, tablet, tablet-s, mobile-l, mobile-m, mobile-s. This seems unnecessarily fine-grained. I think these are sufficient to begin with:

@media screen and (max-width: 768px) { .hide-tablet { display: none !important; } }
@media screen and (max-width: 375px) { .hide-mobile { display: none !important; } }

What can computers do? What are the limits of mathematics? And just how busy can a busy beaver be? This year, I’m writing Busy Beavers, a unique interactive book on computability theory. You and I will take a practical and modern approach to answering these questions — or at least learning why some questions are unanswerable!
