Common Regex
Perl and PHP Regular Expressions
PHP regexes are based on the PCRE (Perl-Compatible Regular Expressions), so any regexp that works for one should be compatible with the other or any other language that makes use of the PCRE format. Here are some commonly needed regular expressions for both PHP and Perl. Each regex will be in string format and will include delimiters.
All Major Credit Cards
This regular expression will validate all major credit cards: American Express (Amex), Discover, Mastercard, and Visa.
//All major credit cards regex
'/^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|6011[0-9]{12}|622((12[6-9]|1[3-9][0-9])|([2-8][0-9][0-9])|(9(([0-1][0-9])|(2[0-5]))))[0-9]{10}|64[4-9][0-9]{13}|65[0-9]{14}|3(?:0[0-5]|[68][0-9])[0-9]{11}|3[47][0-9]{13})*$/'

Count the number of rules and selectors for CSS files on the page. Flags up the >4096 threshold that confuses IE
function countCSSRules() {
var results = '',
log = '';
if (!document.styleSheets) {
return;
}
for (var i = 0; i < document.styleSheets.length; i++) {
countSheet(document.styleSheets[i]);
}
function countSheet(sheet) {

A CSS pseudo-element is used to style specified parts of an element. In some cases you can style native HTML controls with vendor specific pseudo-elements. Here you will find an list of cross browser specific pseudo-element selectors.

Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {
