HTML ordered lists

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 case-sensitive modifier.

CSS

/* List types require the case sensitive flag due to a quirk in how HTML treats the type attribute. */
ol[type="a"] {
  list-style-type: lower-alpha;
  background: red;
}

ol[type="a" s] {
  list-style-type: lower-alpha;
  background: lime;
}

ol[type="A" s] {
  list-style-type: upper-alpha;
  background: lime;
}

HTML

<ol type="A">
  <li>Example list</li>
</ol>
