Is my CSS sent to a server?

No. All processing is done entirely in your browser using JavaScript. Nothing is transmitted to any server and your code never leaves your device.

What is the difference between same-line and new-line brace style?

Same-line style places the opening brace on the same line as the selector (e.g. "body {"), which is the most common convention. New-line style places the opening brace on the following line, similar to Allman style in other languages.

What does "Sort properties alphabetically" do?

Each declaration block has its property-value pairs sorted in ascending alphabetical order by property name. This makes it easier to scan for a specific property and enforces a consistent ordering across all rules.

Will this tool handle nested CSS, media queries, and at-rules?

Yes. The formatter tracks brace depth so nested at-rules like @media, @keyframes, and @supports are indented correctly along with their child rules.
