How to get CSS to select ID that begins with a string (not in Javascript)?

Question

If the HTML has elements like this:

id=\"product42\"
id=\"product43\"
...

How do I match all of those id\'s starting with \"product\"?

Answer 1

[id^=product]

^= indicates "starts with". Conversely, $= indicates "ends with".

The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.

See the specs for full information.
