<p>The HTML specification requires the {{htmlattrxref("type", "input")}} attribute to be matched case-insensitively due to it primarily being used in the {{HTMLElement("input")}} element, trying to use attribute selectors to with the {{htmlattrxref("type", "ol")}} attribute of an {{HTMLElement("ol", "ordered list")}} doesn't work without the <a href="#case-sensitive">case-sensitive</a> modifier.</p>
