Lets fix the short comings of current CSS integrations – EQCSS / Element queries

“Element queries are a new way of thinking about responsive web design where the responsive conditions apply to elements on the page instead of the width or height of the browser.
Unlike CSS @media queries, @element Queries are aware of more than just the width and height of the browser, you can write responsive conditions for a number of different situations like how many characters of text or child elements an element contains.
Another concept that element queries brings to CSS is the idea of ‘scoping’ your styles to one element in the same way that JavaScript functions define a new scope for the variables they contain.”

A better HTML5 parser for PHP – HTML5DOMDocument

HTML5DOMDocument extends the native DOMDocument library. It fixes some bugs and adds some new functionality.

Preserves white spaces
Preserves html entities
Preserves void tags
Allows inserting HTML code that moves the correct parts to their proper places (head elements are inserted in the head, body elements in the body)
Allows querying the DOM with CSS selectors (currently avaiable: *, tagname, tagname#id, tagname.classname, #id, .classname)

<?php
require 'vendor/autoload.php';

$dom = new IvoPetkov\HTML5DOMDocument();
$dom->loadHTML('<!DOCTYPE html><html><body>Hello</body></html>');
echo $dom->saveHTML();

<?php

require 'vendor/autoload.php';

$dom = new IvoPetkov\HTML5DOMDocument();

$dom->loadHTML('<!DOCTYPE html><html><body>Hello</body></html>');

echo $dom->saveHTML();
