Cascade Style Sheets (CSS) is a simple mechanism for adding styles to your web pages.
Practical Applications:
- Consider you have developed a website with around 1000s of web pages. All the web pages background color is white now. In future, if you wanna change the background color of all the pages to light gray color without the need of editing each page separately, CSS helps you to achieve this.
- Have you ever wondered how gmail themes are implemented?! Colors of the background, buttons and texts changes based on the theme applied. They don’t design all the pages separately for each theme. Instead, they will design a common page with only contents and apply these CSS styles over that page.
