Alternative solution for :has selector in Firefox without relying on JavaScript

Currently I am building a small website for a friend and incorporating the :has pseudo class. However, Firefox does not support this feature by default, unless manually enabled. Are there any workarounds available in this case?

I am creating a hamburger menu without relying on JavaScript since 80% of the target audience disables it. After watching a tutorial from Web Dev Simplified, I considered using input["checkbox"], but the absence of the :has pseudo class is proving to be a challenge.

My attempt involved utilizing input:checked::before for adjusting the top bar and input:checked::after for the bottom bar rotation upon click, however, the results were less than desirable!

Answer №1

At present, the :has pseudo-class is not functional in Firefox. To work around this limitation, consider utilizing sibling selectors like + or ~.

For instance:

HTML :

<input type="checkbox" id="menu-toggle">
<label for="menu-toggle">&#9776;</label>
<nav id="menu">
   // menu items
</nav>

CSS :

#menu {
  display: none;
}

#menu-toggle:checked + label + #menu {
  display: block; /* Show menus when checkbox is checked */
}

Create your CSS file tailored to fit your specific design and needs.
