Why use this css escape tool?
Typical uses: • Selecting elements whose IDs contain dots or colons • Building class names from arbitrary strings • Reversing escaped selectors copied from devtools
Because the conversion is deterministic and local, results are identical every time and nothing leaks to third parties.
Both directions live on one page, so you never have to bookmark two tools for one job.
