Case Insensitive CSS Attribute Selector
CSS selectors never cease to amaze me in how powerful they can be in matching complex patterns. Most of that flexibility is in parent/child/sibling relationships, very seldomly in value matching. Consider my surprise when I learned that CSS allows matching attribute values regardless off case!
Adding a {space}i to the attribute selector brackets will make the attribute value search case insensitive:
/* case sensitive, only matches "example" */
[class=example] {
background: pink;
}
/* case insensitive, matches "example", "eXampLe", etc. */
[class=example i] {
background: lightblue;
}
The use cases for this i flag are likely very limited, especially if this flag is knew knowledge for you and you're used to a standard lower-case standard. A loose CSS classname standard will have and would continue to lead to problems, so use this case insensitivity flag sparingly!

![MooTools: Set Style Per Media]()
I'd bet one of the most used MooTools methods is the setStyle() method, which allows you to set CSS style declarations for an element. One of the limitations of MooTools' setStyle() method is that it sets the specific style for all medias.
I just used this in JavaScript to find elements based on title attributes:
let testEntries = document.querySelectorAll('[title^="${search}" i]');Exactly what I was looking for, thanks!
