＆在HTML属性中有效吗？

Question

While writing a series of music options, he called me to attention as Atom expected me to close with a ; after putting a & in the value section.

<option value="R&amp;B/Soul">R&amp;B/Soul</option>
<option value="R&B/Soul">R&amp;B/Soul</option>

Is the first line correct, or is it just an atom error?

Answer 1

Yes, it's correct. ¹ It's pretty clear that you did in fact terminate the character reference with a ; in the right spot, so I don't know why Atom is complaining.

¹ _{In fact, both lines are valid , even if the latter is incredibly bad practice.}
