Basically, a super long string of gibberish characters. It's not gibberish to the browser though of course. This data is interpreted as the type of file you are saying it is.

dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes.

The most popular and trendy of these effects is parallax scrolling. The technique – in which website screens or panels seem to flip with a quick scroll, or objects animate or move – can add an extra level of interest to a site and generate increased user interaction.
But you need a solid understanding of what it is and how to use parallax concepts before you jump on the trend. While it can be a great visual and user tool, parallax effects must be executed with precision.

animate.css is a bunch of cool, fun, and cross-browser animations for you to use in your projects. Great for emphasis, home pages, sliders, and general just-add-water-awesomeness.

В этой книге вы не увидите рассказов о том, как сверстать тот или иной блок или как сделать красивую тень. Напротив, в них подробно описывается сам процесс работы строчного форматирования в CSS, построения строк, инлайн-элементов, механизм влияния на высоту или ширину строки и т.п.
Эта книга будет полезна прежде всего тем, кому важна не только практическая часть CSS, но и теоретическая составляющая, а также тем, кому мало лишь поверхностного знания и есть желание познать таинственные стороны, которые скрываются за ширмой CSS.

Until now. Also, touch-device friendly!
