Can CSS Calculate the Maximum Width of Two Values?

CSS: Achieving Calculation Max Width

In CSS, the enigmatic question arises: is it feasible to ascertain the maximum width using intricate calculations or to compute the maximum of those computations? This article delves into the realm of CSS and explores this intriguing concept.

Calculation of Max

The first query ventures into the possibility of executing a calculation:

<code class="css">max-width: calc(max(500px, 100% - 80px))</code>

Can CSS accommodate such a complex evaluation where the maximum value is determined through a nested function? Regrettably, CSS does not possess this capability, as it cannot ascertain nested maximum or minimum values.

Max of Calculation

The second inquiry explores an alternative approach:

<code class="css">max-width: max(500px, calc(100% - 80px)))</code>

This approach seeks to determine the maximum of two values: 500px and a calculated percentage. However, this syntax is also incompatible with CSS, which lacks the capacity to evaluate the maximum of expressions.

CSS Workaround

While pure CSS methods for achieving this result elude us, a pragmatic solution emerges. Media queries provide a clever workaround:

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

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

By employing media queries, we can conditionally apply maximum width values based on the viewport's width. This technique mimics the desired functionality, ensuring that the maximum width is adjusted dynamically as the device screen size varies.
