Description: Selects elements that have the specified attribute with a value beginning exactly with a given string.
This selector can be useful for identifying elements in pages produced by server-side frameworks that produce HTML with systematic element IDs. However it will be slower than using a class selector so leverage classes, if you can, to group like elements.
