CSS3 Tutorial

In website design, CSS is the most important presentational technology.

Cascading Style Sheets, commonly known as CSS, is a widely adopted language for defining how web pages should appear and be formatted.

It enables the separation of presentation concerns from the content within HTML documents. In the pre-CSS era, formatting attributes such as font colors, background styles, alignments, borders, and sizes were directly specified within HTML tags. However, CSS revolutionized web design by allowing the styling information to be stored separately in CSS files, resulting in cleaner and more maintainable HTML code.

Since a result, developing huge websites became a time-consuming and costly process, as style information was added to each page of the website many times.

To resolve this issue, The World Wide Web Consortium (W3C) first introduced CSS in 1996, and it is still in use today. CSS was created to allow display and content to be separated. Web designers may now relocate web page formatting information to a separate style sheet, resulting in significantly cleaner HTML syntax and improved maintainability.

The CSS3 specification is the most recent version of the CSS specification. CSS3 introduces a number of new stylistic elements and enhancements to improve online appearance.

Note: Our CSS lesson will guide you through the principles of the current CSS3 language, starting with the basics and progressing to more advanced subjects. If you're a newbie, start with the basics and work your way up by learning something new every day.

What You Can Do with CSS

There's a lot more that CSS can do for you.

  • The same style rules may be readily applied to several components.
  • A single style sheet can be used to modify the appearance of several pages on a website.
  • On different devices, the same website might be shown differently.
  • You can style dynamic states of components like hover, focus, and so on in ways that you couldn't before.
  • You can move an element around on a web page without affecting the HTML.
  • Existing HTML components can have their appearance changed.
  • Scale, rotate, skew, and other components can be transformed in 2D 3D space.
  • Without utilising JavaScript, you may create animations and transition effects.
  • Print-friendly versions of your web pages are possible to build.

There are many more intriguing things you can accomplish with CSS that aren't included in this list. In the next chapters, you'll discover more about each of them.

Advantages of Using CSS

The most significant benefit of CSS is that it allows you to separate the document's style and layout from its content. Here are a few additional reasons to begin utilising CSS.

  • CSS Saves Time – CSS provides you a number of options for customising an element's stylistic characteristics. Once you've written CSS, you may apply it to groups of HTML components and reuse it across different sites.
  • Easy Maintenance - CSS makes updating document formatting and maintaining uniformity across many documents a breeze. Because one or more style sheets can influence the content of the complete collection of web pages.
  • Pages Load Faster - CSS allows many pages to exchange formatting information, which lowers document complexity and duplication. It decreases file transmission size greatly, resulting in quicker website loading.
  • Superior Styles to HTML - CSS outperforms HTML in terms of presentation capabilities and gives you far more control over the layout of your web pages. As a result, compared to HTML presentational elements and attributes, you can give your web pages a much better look.
  • Multiple Device Compatibility - CSS also allows web pages to be optimised for multiple devices or media. The same HTML document can be presented in various viewing styles for different rendering devices, such as desktops, mobile phones, and so on, using CSS.

Tip: Most HTML attributes are now obsolete, and their usage is discouraged. So, to boost the flexibility of your website and make it compatible with future browsers, it's a good idea to utilise as much CSS as feasible.
