In context uses
To escape a string for use as part of a selector, the escape()
method can
be used:
js
const element = document.querySelector(`#${CSS.escape(id)} > img`);
The escape()
method can also be used for escaping strings, although it
escapes characters that don't strictly need to be escaped:
js
const element = document.querySelector(`a[href="#${CSS.escape(fragment)}"]`);
