Frequently Asked Questions
Does this show exact browser version support like MDN compatibility tables?
No. The support column is deliberately coarse. Entries are marked only as “All modern browsers” or “Modern browsers,” so you do not get per-browser version breakdowns here.
Are the default values in this table always the exact computed defaults from the spec?
Treat them as quick-reference defaults, not a full computed-style engine. Some shorthand rows are intentionally generalized, such as background showing “see longhand defaults.”
What gets copied when I click a property button?
Only the property name. Clicking background-size copies background-size, not the syntax string or default value.
Can I narrow the table to just Flexbox, Grid, or animation properties?
Yes. The category tabs split the reference into groups like Flexbox & Grid, Effects & Animation, Typography, and Background & Color.
Is this every CSS property that exists?
No. The page is built from a fixed seed list of common properties. It covers a lot of day-to-day CSS, but it is not a complete property index.
