Illegal Characters In Attributes

[fweth]

Hi, I just used the < character in some JS code for Alpine in a HTML attribute, and VScode marked it red, but still seemed to work and the browser didn't complain. I looked up the spec and interestingly, they claim that just the other way around, > is not valid in HTML attributs. So anyway, I just wondered, could this be a problem for some browsers? They also claim = is not valid, which would make writing JS for Alpine really hard.

They are talking about the name of the attribute. <tag name="value">
The = is used by the browser to separate the name and the value.
What is your use case for having an = in an attribute name?

Hey, thanks for the answer, maybe I didn't understand the spec correctly. I just had something like x-show="a < b" and VScode marked the < in red, so I wondered, if there are any characters which I chouldn't use inside Alpine attributes.

except for the double quotes symbol which conflicts with the value terminator, I'm not aware of any other restrictions.

OK, thanks a lot!
