I think this Google rule is too specific and in the same time too general for being alive.<p>The whole idea :<p>&gt; Inline small CSS.<p>is too specific. I think when you work on a huge web-application you don&#x27;t want to create such a bloat in your <i>layouts</i> and personally I don&#x27;t think that this approach scales. On the other hand if you go with a simple web page, like a landing page with a couple of elements ... go for it.<p>&gt; If the external CSS resources are small<p>What is &quot;too small&quot; anyway ? ( too general )
