Why Isn\'t My calc() Function Working?

Calc() Function Woes: Why It's Not Working

Your calc(100vw/4) function is functioning as expected, but the others are not because of a crucial element: spaces.

The CSS calc() function requires spaces between its operators. Common errors include omitting these spaces, leading to invalid expressions.

For instance, the expression calc(100vw/4-(10-4)) is invalid because of the missing space between "-" and the parentheses. Instead, it should be: calc(100vw/4 - (10 - 4)).

Nested Calc() Functions

You can nest calc() functions as many times as needed, but it functions the same way as parentheses. For example:

<code class="css">calc(100vw/4 - calc(10px - 4px))</code>

Is equivalent to:

<code class="css">calc(100vw/4 - (10px - 4px))</code>

Example

Here's an example of a nested calc() function:

<code class="css">.one {
  width: calc(100% - 150px);
  margin-top: calc(20px + calc(40px * 2));
  height: calc(100px - 10px);
  padding: calc(5% + 10px) calc(5% - 5px);
}</code>

In this example, the margin-top property uses a nested calc() function to add 20px to the result of multiplying 40px by 2.
