css - Intermittent failure of Mailto: attribute in HTML code -

<div class="transeffect">   <span style="font-size:1.5em;padding-top:7px;color:red" class="glyphicon glyphicon-envelope"><a href"mailto:someone@example.com"> &nbsp;someone@example.com</a></span>  </div>

the above code not working. in part of document, have this

<p><span class="glyphicon glyphicon-envelope" aria-hidden="true"></span> <a style="text-decoration:none" href="mailto:someone@example.com">someone@example.com</a></p>

this code works perfectly. please. thanks.

that's because you're missing '=' between href , mailto url in first snippet. second snippet okay.
