🧮CSS calc() Helper
The CSS `calc()` function is a powerful tool that lets you perform mathematical calculations right in your CSS. It's especially useful for mixing units, for example, making an element take up the full width of its container minus a fixed pixel value (`width: calc(100% - 30px)`). Our helper makes writing this syntax trivial. Enter your two values and choose an operator, and the tool provides the correctly formatted `calc()` expression, complete with the required spacing, ready to be used in your stylesheet.
Frequently Asked Questions
Why are the spaces around the operator important?
For addition (+) and subtraction (-), the CSS `calc()` syntax requires whitespace on both sides of the operator. Without the spaces, the expression is invalid. This tool adds them for you automatically.
Can I chain multiple calculations?
Yes, `calc()` supports nested calculations (e.g., `calc(100% / 3 - 2 * 1em)`). This is a simple two-value helper, but you can manually combine its output to build more complex expressions.
