Advantages of CSS3

CSS3 is the latest version of the CSS specification. It adds many powerful new features based on CSS2.1. To help developers solve some practical problems. Using CSS3 can not only design cool and beautiful web pages, but also improve web page performance. Compared with traditional CSS, the most prominent advantages of CSS3 are mainly reflected in cost saving and performance improvement, which will be introduced in detail in this section.

The most obvious thing is that CSS3 can make the page look very flashy and cool, making the website design even better, but its benefits go far beyond that.

In most cases, using CSS3 is not only beneficial to development and maintenance, but also improves website performance. At the same time, it can also increase the accessibility and usability of the website, enable the website to adapt to more devices, and even optimize the website SEO and improve the search ranking results of the website.

Reduce development and maintenance costs

Why is CSS3 able to reduce development and maintenance costs?

Let’s look at an example first. A rounded corner effect requires adding additional HTML tags in CSS2 and using one or more images to complete; while using CSS3, it only requires one tag and a border-radius attribute. In this way, CSS3 technology can save people from the work of drawing, cutting and optimizing images.

If you need to adjust the curvature or color of the rounded corner later, if you use CSS2, you have to draw and cut the image from scratch to complete it. However, using CSS3, you can complete these tasks in a few seconds.

CSS3 can also keep us away from a lot of JavaScript script code or Flash. We no longer need to spend a lot of time writing scripts or finding suitable script plug-ins and modifying them to adapt to website special effects.

Finally, some CSS3 techniques can also help simplify the page and make the structure clearer. For example, nesting many div tags and class names to achieve an effect can effectively improve work efficiency, reduce development time, and reduce development costs. For example, to create an overlapping background effect, you need to add div tags and class names in CSS, and put a background image in different divs. Now you can use the new features of CSS3 such as multiple backgrounds and background sizes, and add it to a div tag. can complete these tasks.

Improve page performance

When developing for the Web, reducing redundant tag nesting and the number of images used means that users will have to download less content. , the page will load faster. In addition, fewer images, scripts, and Flash files allow the website to reduce the number of HTTP requests, which is one of the best ways to improve page loading speed.

Using CSS3 to create a graphical website without any images can greatly reduce the number of HTTP requests and improve the page loading speed.

Of course, this depends on what technology the CSS3 features are used to replace, and it also depends on how the CSS3 features are used. For example, CSS3 animation effects can reduce HTTP requests for JavaScript and Flash files, but may require the browser to perform a lot of work to complete the rendering of the animation effects, which may cause the browser to respond slowly and lead to user loss.

Therefore, everyone needs to think carefully when using some complex special effects. However, such phenomena are rare after all.
