Question

Let’s say I have

<span class="1">hello</span>

And I want to declare:

span.1 { /* rules */ }

This does not seem to work (i.e. the CSS rule is not being applied.) Is there a way to get this to work? I tried just quoting the “1” in the CSS selector but that doesn’t appear to be it.

Answer 1

See this: Which characters are valid in CSS class names/selectors?

a (class) name must begin with an underscore (_), a dash (-), or a letter(a–z)
