HTML issues tagged as space.
<a> tags can be used to link to an email address using the
mailto protocol in the
href attribute. Ensure that there is no space in the email address.
<a href="mailto: firstname.lastname@example.org">This is wrong as it contains an space</a> <a href="mailto:email@example.com">This is OK</a>
href attribute on an
<a> link contains a space character, which is not allowed. If you’re trying to link to a phone URL, review the
href attribute to remove unallowed characters, as in this example:
<!-- Invalid as it contains a space character --> <a href="tel: +123456789">call me</a> <!-- Valid --> <a href="tel:+123456789">call me</a>
