Question:
Are there any restrictions or problems in using the tag a without the attribute href ?
Example: <a>teste</a> .
Answer:
In HTML5 it is valid and can be used to later be completed by a script , as indicated in the official documentation . Something like:
document.getElementById("link").href = "http://pt.stackoverflow.com";<a id="link">Vai ter um link aqui</a>I put it on GitHub for future reference .
