side notes

p.note {
    border-style: solid;
    border-width: 1px;
    border-left-width: 15px;
    padding: 10px;

Note: The "border-left-width" property does not work if it is used alone. Use the "border-style" property to set the borders first.

Attributes Selection

CSS3 Pseudo-elements

Pseudo-elements are not pseudo-classes. In contrast to pseudo-classes, pseudo-elements can be used to style a specific part of an element. More on pseudo-elements at [MDN][mdn-pseudoel.

<q> for short quotation

Here is an example of using ::before and ::after pseudo-elements:

/* open and closing quotes like in Polish language */
Q               { quotes: "\201E" "\201D" }
Q::before       { content: open-quote }
Q::after        { content: close-quote }

/* quotes like << >> */
Q1               { quotes: "\00AB" "\00BB" }
Q1::before       { content: open-quote }
Q1::after        { content: close-quote }

And results:

Open and closed quotes.

Using an extra tag (Q1) here we have an << >> quotes.

CSS3 Rounded Corners

With CSS3, you can give any element “rounded corner”, by using the border-radius property. Radius from CSS Reference. Also some border-radius tricks.

Here is for the background.

This example is for the border.

This example is for a background image.

CSS3 Shadow Property

At example above (CSS3 Rounded Corners) you can clearly see shadowed boxes. This is how box-shadow property works. The text-shadow property is applied to each h1,h2 headers.

The subject is elaborated at W3Schools.

CSS3 Multiple Backgrounds

CSS3 allows you to add multiple background images for an element. The different background images are separated by commas, and the images are stacked on top of each other.

More details on CSS3 backgrounds may be found at W3Schools.

CSS3 Gradients

Diagonal Gradients
7 Color Stops
Radial Gradients

Multiple options are available. A lot of examples can be found at W3Schools.

RGBa Browser Support

RGBa is a way to declare a color in CSS that includes alpha transparency support.

By setting the CSS opacity property, we can adjust the transparency of the entire element and its contents. RGBa colour gives us something different – the ability to control the opacity of the individual colours rather than the entire element.

It looks like this:

#rgbatest {
  color: rgba(255,255,255,.8);
  background-color: rgba(142,213,87,.3);
#rgbatest:hover {
  color: rgba(255,255,255,1);
  background-color: rgba(142,213,87,.6);

Transformations and Transitions

CSS3 Transformations

This example is for the border.
Rotation: 0

The example above uses HTML5 input type="range", and W3 wiki describes all its attributes.

W3Schools describes CSS3 2D and 3D transformations.

CSS3 Transitions

CSS3 Transitions are not transformations. Using them together adds dynamic feeling to a page.
