The :before and :after pseudo-elements inherit any inheritable properties from the element in the document tree to which they are attached. For example, the following rules insert an open quote mark before every Q element.
Everything else is vanilla CSS, ::after, ::before are pseudo elements, .relative and .radio are class selectors, :checked is a pseudo class for input types radio and checkbox, and + is an adjacent sibling selector
The ::before notation (with two colons) was introduced in CSS3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :before introduced in CSS 2.
So I read the docs and probably understand the purpose of ::before and ::after. If my understanding is correct, they should always work in combination with other elements. But the web page I'm look...

The code marked @Before is executed before each test, while @BeforeClass runs once before the entire test fixture. If your test class has ten tests, @Before code will be executed ten times, but @BeforeClass will be executed only once. In general, you use @BeforeClass when multiple tests need to share the same computationally expensive setup code. Establishing a database connection falls into ...
If the VirtualService using the subsets arrives before the DestinationRule where the subsets are defined, the Envoy configuration generated by Pilot would refer to non-existent upstream pools. This results in HTTP 503 errors until all configuration objects are available to Pilot.
The before and after pseudo-selectors don't insert HTML elements — they insert text before or after the existing content of the targeted element. Because image elements don't contain text or have descendants, neither img:before or img:after will do you any good. This is also the case for elements likeand

::before is the new implementation of the older :before -- it was to distinguish the difference between pseudo-elements (::) and pseudo-classes (:). Having said that, IE 8 only accepts :before and not the new syntax, while new browsers accept both, so it's better off using the old syntax if you want better compliance.

One thing that ::before and ::after have in common and MUST have to work, is the content attribute. If it doesn't have a content attribute it wont show up. Don't mistake this as having a blank content, though, as this will work provided you give it a height/width like any other element.
Hence, a:hover::before and a:visited::before. But if you're developing for legacy browsers such as IE8 and older, then you can get away with using single colons just fine. This specific order of pseudo-classes and pseudo-elements is stated in the spec: One pseudo-element may be appended to the last sequence of simple selectors in a selector.
However, all before hooks that apply are executed before any beforeEach hook. This explains the order above: sublevel before executes before top beforeEach because it is a before hook. And with after and afterEach, the same logic applies but the the order is reversed: all afterEach hooks that apply are executed before any after hook.
