Today, we see a variety of web pages because of images. Think about the past, all the web pages on the Internet are plain text pages. It's boring to know the importance of images in web page design. You can insert images into html pages. common image formats include JPEG and GIF:
JPEG (Joint Photographic Experts Group) is a file format specially designed for photo images. JPEG supports millions of colors. JPEG is a loss-quality format, which means that some image data is lost during compression, which reduces the quality of the final file. However, image data is rarely discarded and there is no obvious difference in quality.
GIF is a popular format in web images. Although it only includes 256 colors, GIF provides excellent, almost no loss of image compression. In addition, GIF can contain transparent areas and multiple animations. It compresses a fixed color area by scanning pixel lines horizontally, and then reduces the number of pixels in the same area. Therefore, GIF is usually applicable to cartoons, images, logos, images with transparent areas, and animations.
You can insert images to beautify the page. There is only one tag for inserting an image, that is, the tag. When inserting an image, it is not enough to only use the tag. You need to use other attributes to complete the process, as shown in the following table.
