Can CSS Select Elements Without a Specific Class or Attribute?
Can One Write CSS to Select Elements Lacking a Class or Attribute?
This issue arises when one wishes to select elements that do not possess a specific class or attribute. For instance, consider the HTML below:
<html class="printable">
<body class="printable">
<h1 class="printable">Example</h1>
<nav>
<!-- Some menu links... -->
</nav>
<a href="javascript:void(0)" onclick="javascript:self.print()">Print me!</a>
<p class="printable">
This page is super interresting and you should print it!
</p>
</body>
</html>In this case, we aim to select the elements without the "printable" class, namely the nav and a elements.
Solution:
Traditionally, one can achieve this with the :not() pseudo-class applied to a class selector:
:not(.printable) {
/* Styles */
}
:not([attribute]) {
/* Styles */
}However, for enhanced browser compatibility (IE8 and below lack :not() support), it is recommended to style elements that do possess the "printable" class. If this is impractical, modifying the markup may be necessary.
Considerations:
Properties set within this rule may affect descendants with the "printable" class. For example, setting display: none on :not(.printable) will conceal both it and its descendants. Instead, consider using visibility: hidden to allow descendants to display while maintaining the original layout. Caution is therefore advised.
