I implemented the common "read more button" function with this plug-in ↓
The question I was interested in was "Why is the a tag?"
By the way, I see that the a tag is also used for the "scroll button to return to the top of the screen".
Why is it an a tag even though it does not change pages?
I think the button tag is fine, but is there any reason why the a tag is more suitable?
Answer # 1
Is there any reason why the a tag is more appropriate?
There is nothing in particular.
It depends on what kind of decoration you want, but since the a tag is mostly raw text, I personally think that the decoration is easy depending on the requirements.
The rest seems to be the specifications of the plug-in (probably it doesn't work if you just change the tag), so there may be some idea of the creator.
