Case Insensitive CSS Attribute Selector

CSS selectors by no means stop to amaze me in how highly effective they are often in matching complicated patterns. Most of that flexibility is in guardian/baby/sibling relationships, very seldomly in worth matching. Take into account my shock once I discovered that CSS permits matching attribute values regardless off case!

Including a {house}i to the attribute selector brackets will make the attribute worth search case insensitive:

/* case delicate, solely matches "instance" */
[class=example] {
  background: pink;
}

/* case insensitive, matches "instance", "eXampLe", and so forth. */
[class=example i] {
  background: lightblue;
}

The use instances for this i flag are seemingly very restricted, particularly if this flag is knew data for you and also you’re used to an ordinary lower-case normal. A unfastened CSS classname normal can have and would proceed to result in issues, so use this case insensitivity flag sparingly!
