FAQFrequently asked questions
Does the CSS formatter upload my styles?
No. Formatting and minification run locally in your browser, so the CSS is not sent to an MTKits server.
What does formatting change?
Beautifying rewrites whitespace and line breaks so selectors, properties, and nested rules are easier to read. It does not change the meaning of valid CSS.
What does minifying remove?
Minifying strips comments and collapses unnecessary whitespace so the stylesheet is smaller for production.
Will minifying break my CSS?
It only removes comments and redundant whitespace. Selectors, values, and at-rules stay the same, so rendered styles should match.
