What is CSS 2D Transforms?

CSS 2D Transforms is part of the CSS3 standard being developed (it is currently in draft status).
Two-dimensional transformations allow us to describe the affine transformations of various elements through CSS: transfer, scaling, rotations and tilts, including through the transformation matrix.

For example, such a css-style

  div { 
     transform: translate (100px, 100px);

Shifts the element to which it applies 100px down and to the right:

To make additional scaling and rotation by 45 degrees, you need to specify the scale through the scale and the angle of rotation through rotate in the transformation:

  div {
       height: 100px;  width: 100px;
       transform: translate (80px, 80px) scale (1.5, 1.5) rotate (45deg);

Important: since this part of the CSS is still being developed and is far from Candidate Recomendation, for IE9 PP6 it has been added in experimental mode and the -ms- prefix must be added to the properties, for example, -ms-transform.

What are semantic tags?

Semantic tags are tags entered in html5 that help make the page layout more meaningful. A complete list of new tags and changes from html 4.01 can be found here http://www.w3schools.com/html5/html5_reference.asp

The following tags are currently recognized: section, nav, article, aside, hgroup, header, footer, figure, figcaption, mark.
