Inline style includes the deprecated font tag, inline style blocks, and nonbreaking spaces. Inline style such as:
<p style="font-size:12px;color:black;">Hardcoded text here.</p>
<p style="font-size:12px;color:black;">Inline style redux</p>
bulks up your code and makes it harder to make style changes. It is more efficient to abstract multiple duplicate styles into CSS rules, like so:
<style type="text/css">
p{font-size:12px;color:#000;}
</style></head></body>
<p>Unencumbered text here</p>
<p>Free and easy</p>
