CSS is the preferred technology to design modern web pages.

We'll quickly take you through CSS3's features, and show you how to resolve common issues so you can build your basic framework. Finally, you will learn about code architecture and CSS methodologies used in scalable apps and you'll explore the various new features of CSS3, such as FlexBox, to help you create the most modern layout methodologies. By the end of the book, you will be a master at creating pure CSS web pages and will know sophisticated web design techniques, giving you an edge over other web designers.

Short forms of useful elements


In CSS code (and not only CSS), you wish to get the final effect more quickly each time you repeat a part of the code. So why don't you create short forms for some CSS declarations as well? Let's check what we can make shorter:

/* Text decoration */
=tdn
  text-decoration: none

=tdu
  text-decoration: underline


/* Text align */
=tac
  text-align: center

=tar
  text-align: right

=tal
  text-align: left


/* Text transform */
=ttu
  text-transform: uppercase

=ttl
  text-transform: lowercase


/* Display */
=di
  display: inline

=db
  display: block

=dib
  display: inline-block


/* Margin 0 auto */
=m0a
  margin: 0 auto

Now, each time you want to make some text uppercase, you are just using code:

.sampleClass
  +ttu

Here's the compiled CSS:

.sampleClass {
    text-transform: uppercase;
}

Another example of usage of short mixins is a element which will be displayed as a block element and text will be centered:

.sampleClass
  +db
  +tac

Here's the compiled CSS...
