Learning LESS (Video 10)

The video tutorial covers the concept of nesting in LESS, a CSS pre-processor. It begins with an introduction to the benefits of nesting, such as improved code organization and conciseness. The tutorial then provides a practical example using a container class, demonstrating how to implement nesting by indenting child classes within parent classes. It highlights the advantages of nesting, including faster and leaner code writing, while also cautioning against over-nesting due to potential specificity issues. The video concludes with a brief mention of advanced nesting techniques to be covered in the next video.

What is one of the main benefits of using nesting in LESS?

• It increases the file size.

• It helps in organizing and writing concise code.

• It requires more lines of code.

• It makes the code harder to read.

How can you nest a child selector within a parent class in LESS?

• By writing the child selector in uppercase.

• By using a period before the child selector.

• By indenting the child selector within the parent class.

• By using a semicolon.

What is the result of saving a LESS file with nested selectors?

• The CSS output will have no nested selectors.

• The CSS output will be empty.

• The CSS output will be the same as the LESS file.

• The CSS output will have fully named selectors.

What is a potential issue with excessive nesting in LESS?

• It makes the code run faster.

• It can lead to CSS specificity problems.

• It simplifies the CSS cascade.

• It reduces the number of selectors.

What is the recommended maximum level of nesting in LESS to avoid specificity issues?

• One level

• Two levels

• Three levels
