I am trying to add to an HTML email an element in this case an anchor where the content of this element "Hello" can be selected on click/on touch by the recipient.
<div>
<a>Hello</a>
<div>
I have tried adding this style inlined:
-webkit-touch-callout: default;
-webkit-user-select: all;
-khtml-user-select: all;
-moz-user-select: all;
-ms-user-select: all;
user-select: all;
but this inline style is ignored (stripped from the html when opening the email in gmail web app for example.
This is an advanced feature of CSS (CSS3) and as such most email clients do not support it. They barely support the basics!
