How to introduce images in HTML (two methods)

HTML (Hypertext Markup Language) is one of the basic languages ​​​​of Web pages. Whether you are building a static page or a dynamic page, HTML is an indispensable part. Pictures are one of the very important and commonly used elements when creating web pages, so we need to know how to introduce pictures in HTML.

HTML can introduce multiple types of images, such as .gif, .jpeg, .png and other formats. Before introducing images, we need to create an image folder for the HTML document to store all image files. Usually, the picture folder is placed in the same directory as the HTML file so that the HTML file can easily access them.

In HTML, we can use the following two methods to reference images into Web pages.

1. Using images in tags

The most common way is to use the img (image) tag in an HTML document, which is very simple and easy to use. The following is the basic syntax of the tag:

<img src="image filename">

Among them, the src attribute is used to tell the browser where to load the image, and image filename is the name of the image file (note that the relative path should be given here, not absolute path).

For example, if our picture folder and HTML file are located in the same directory, and we want to introduce an image named "example.gif" into the Web page, then the code will be as follows:

<img src="example.gif">

This will display the image named "example.gif" on the page.

If we want to add more attributes to the image, such as letting it link to other web pages, add titles, change width and height, etc., we can use the following tags:

<img src="image filename" alt="Image title" title="Image tooltip" height="number" width="number" border="number" align="left/right/center">

Where, The alt attribute is used to add the image name, which will be displayed when the image cannot be displayed; the title attribute will add prompt text; the height and width attributes are used to change the size of the image; the border attribute is used to add the border width; the align attribute is used to control the image and The alignment of other text.

For example, if we wanted to add an image with a width of 200 pixels and a height of 100 pixels, and link it to another page, the code would look like this:

<a href="https://www.example.com/"><img src="example.gif" alt="Example Image" title="Click this image to go to example.com" height="100" width="200" border="1" align="center"></a>

2. Use CSS to create pictures in the background

We can also use CSS (Cascading Style Sheets) to add pictures in the background of the web page, which is another common method. Unlike the tag, this method uses the image as the background of the entire web page rather than as a separate element.

The following is how to add images in the background using CSS:

body {
    background-image: url('image filename');
}

Among them, the background-image attribute is used to tell the browser the image that needs to be displayed in the background. It can also have other options. , such as setting the background color and tiling method of the background image, etc.

For example, if we wanted to display an image named "example.gif" in the background of a web page, and have it repeat horizontally and vertically, the code would look like this:

body {
    background-image: url('example.gif');
    background-repeat: repeat;
}

This will cause the background of the entire page to be filled with the "example.gif" image.

When using this method, we need to pay special attention to the size of the images to ensure that they display correctly on different types of devices.

Summary

Whether you use images in the tag or use CSS to add images in the background, HTML provides various ways to introduce images. When using these methods, we need to pay attention to the size, path, and format of the images to ensure that they can be displayed correctly in the Web page. By using images in HTML, we can easily add personalized elements to web pages, making them more rich and attractive.
