I stumbled upon the snippet of code shown above on a website discussing CSS image galleries. Can anyone clarify what this code accomplishes? Appreciate it.
This is a demonstration of combining an attribute selector with the use of a :target pseudo class.
The purpose of this code snippet is to apply specified styles to any element that has a certain attribute value and is the target of a hyperlink anchor.
In particular, it targets all div elements with an id attribute starting with ('^=') the text 'image', and applies the defined style when these elements are clicked from an anchor link.
According to MDN (where 'attr' represents the attribute used in selection):
[attr] Selects an element with the specified attribute name.
[attr=value] Selects an element with the given attribute name/value combination.
[attr~=value] Targets an element with an attribute containing a list of whitespace-separated words, one of which matches "value".
[attr|=value] Matches an element with an attribute starting exactly with "value" or "value-" for language subcodes.
[attr^=value] Selects elements with an attribute beginning with "value".
[attr$=value] Chooses elements with an attribute ending in "value".
[attr*=value] Finds elements with an attribute containing "value" as a substring.
The various operators allow for precise identification of attribute values using attribute selectors.
:target pseudo-classThe
:targetpseudo-class selects the unique element with an id matching the URI fragment identifier of the document.
