Can You Use Mathematical Expressions within the `max-width` Property in CSS?

Achieving Max Width Calculations in CSS

Is it possible to utilize mathematical expressions within the max-width property in CSS, such as:

max-width: calc(max(500px, 100% - 80px))

or

max-width: max(500px, calc(100% - 80px)))

Answer:

While direct calculation within the max-width property was previously not possible, modern CSS introduces a workaround using media queries:

<code class="css">.yourselector {
  max-width: calc(100% - 80px);
}

@media screen and (max-width: 500px) {
  .yourselector {
    max-width: 500px;
  }
}</code>

This approach sets the max-width to be relative to the viewport width with a minimum of 500px, ensuring that the element does not exceed that width even when the parent container is wider than 500px.
