Learning LESS (Video 16)

This video tutorial explores the use of 'extends' in LESS to enhance CSS workflow by reducing code repetition. It explains how classes can inherit styles from other classes, demonstrated through a practical example. The tutorial also covers the implementation process, highlighting the benefits and potential caveats, such as the inability to extend nested selectors by default and limitations within media queries. The video concludes with a discussion on organizing code effectively.

What is the primary benefit of using 'extends' in LESS?

• It allows for the use of variables in CSS.

• By removing the need to declare '.message' in HTML.

What is a key difference between mixins and extends in LESS?

• Extends are more flexible than mixins.

• Extends can use arguments, while mixins cannot.

• Mixins are faster to compile than extends.

• Mixins can use arguments, while extends cannot.

What must be added to an extend statement to include nested selectors?
