About CSS comparison
Compare CSS with confidence.
Review a design tweak, compare a theme before and after, or check what a minifier changed.
Ignore whitespace
Hide indentation and spacing differences between formatters.
Spot value changes
A changed colour or size shows as a single modified line.
Private by design
Your styles stay in the browser and are never uploaded.
Features
Quiet tools, sharp results.
Aligned side by side
Two editors scroll together so the line you are reading always faces its counterpart.
Every change, coloured
Ember marks edits and removals. Ink marks additions. No other colours to learn.
Jump between differences
Step forward and back through each change with a count of how many remain.
Ignore the noise
Switch off whitespace and letter-case differences to focus on what really matters.
Changes, explained
A line-by-line list says what happened to each line, such as “Friday” became “Monday” or a number went from 3 to 4. Click any entry to jump straight to it.
How it works
Three steps. No account.
Paste
Drop the original on the left and the new version on the right.
Compare
Differences are highlighted as you type, line by line.
Decide
Review the summary, swap sides or clear the editors and go again.
