Add images to web pages: choose img or CSS?

In web development, images and CSS style sheets are very important. When designing a website, we need to decide how to display and optimize these elements to ensure that the site loads and renders as quickly as possible.

In traditional website development, images and CSS style sheets are two separate files. Now, with the development of technology, we can integrate images and CSS style sheets, resulting in a new technology: img or css.

So, should I use img or css? This needs to be judged on a case-by-case basis.

First of all, for displaying some large pictures or picture libraries, it would be better to use img. Because img can provide high-quality images and can also support more file formats, such as JPEG, PNG, and GIF. Additionally, img can also be easily scaled and cropped, providing a better user experience.

However, for some small icons, lines and shapes, etc., it may be better to use CSS. Because CSS can be used to create almost any type of shape, including circles, rectangles, triangles, etc., you can also set effects such as gradients and shadows to enhance the visual effect. This reduces website loading time and improves speed and performance.

In addition, if we want to put some graphics into the text, such as numbers, letters, etc., then CSS will be better. In this case, we can use the font customization feature to define all the fonts we need in a single CSS file and use it in the HTML file.

Finally, when we need to process multiple elements at the same time, using img and css combined is also a good way. For example, we can use img to display the main background of the website, use CSS to set more detailed graphics and interface elements, and add dynamic effects and interactive functions to page elements.

In general, choosing img or CSS depends on the specific situation. Either approach requires careful consideration to ensure that our website best meets the needs and expectations of our users.
