HTML <tt> Tag
Not Supported in HTML5.
The <tt>
tag was used in HTML 4 to define teletype text.
What to Use Instead?
Consider the <kbd> element (for keyboard input), the <var> element (for variables), the <code> element (for computer code), the <samp> element (for computer output), or use CSS instead.
Example
Define a teletype/monospace font for a <p> element (with CSS):
<p style="font-family:'Lucida Console', monospace">This text is monospace
text.</p>
