OK, so this part is new to me:<p><i>Don&#x27;t inline CSS attributes</i><p><i>Inlining CSS attributes on HTML elements (e.g., &lt;p style=...&gt;) should be avoided where possible, as this often leads to unnecessary code duplication. Further, inline CSS on HTML elements is blocked by default with Content Security Policy (CSP).</i><p>How effective is this, really? If I can inline a CSS class, then I can inject any style on any HTML element even if I can&#x27;t inline an attribute. Am I missing something here?
