Can I calculate a value based on another value? Here's an example:
.my-div {
width: 50px;
height: calc(width * 2)
}
Is this doable?

For more information about using the calc function in CSS, check out the MDN article provided.
Although the use of calc is an innovative feature, it may not always be necessary, as demonstrated in the following example:
.my-div {
width: 50px;
height: calc(50px * 2);
}
In some cases, using calc may not add much value when the width is already known. In these situations, utilizing a library like jQuery or vanilla JS may be a more suitable solution.
Unfortunately, CSS alone cannot achieve this effect. However, tools such as SASS and LESS have been created to make it possible. This is just one example of how CSS preprocessors can enhance styling capabilities.
I suggest visiting their websites for further details.
Starting from 2015, it has become possible to achieve this effect using only CSS by utilizing CSS custom properties :
.custom-div {
--size: 50px;
width: var(--size);
height: calc(var(--size) * 2);
}
