It’s a pseudo-element, as defined by the CSS Selectors Level 3 spec: The ::before and ::after pseudo-elements can be used to describe generated content before or after an element’s content. It is effectively the same as the single-colon syntax defined by the level 2 spec. The level 3 spec introduces an extra colon to differentiate … Read more
$(“td:contains(‘c’)”).html(“new”); or, more precisely $(“#table_headers td:contains(‘c’)”).html(“new”); and maybe for reuse you could create a function to call function ReplaceCellContent(find, replace) { $(“#table_headers td:contains(‘” + find + “‘)”).html(replace); }
:nth-child() pseudo-class looks through the children tree of the parent to match the valid child (odd, even, etc), therefore when you combine it with :not(.hidden) it won’t filter the elements properly. Alternatively, we could fake the effect by CSS gradient as follows: .hidden {display:none;} .wrap { line-height: 1.2em; background-color: orange; background-image: linear-gradient(transparent 50%, green 50%); … Read more
Every sequence of simple selectors and combinators is read by browsers from right to left, in a linear fashion. Combinators do not affect the ordering in any way. The rightmost selector, after the last combinator if any, is known as the key selector (see the reference links below for more), and that identifies the element … Read more

This means that an element’s text color is inherited from the parent. You’re seeing this in your code. In contrast, the border property is … Read more

If the rules are equal in specificity (in this case they are), individual rules get overridden in the order they’re defined in the CSS, so in your example red wins because it comes later in the CSS definitions. The same rule applies in other cases as well, for example: <div class=”red green”> Which of these … Read more
