What is the code to add pictures in html

htmlThe code for adding pictures is "". The src attribute is used to specify the path of the picture. The path can be a relative path or an absolute path. A relative path is a path relative to the current HTML file. An absolute path is a complete URL, which can be a file path on the local file system or a file path on a remote server. The alt attribute is used to provide alternative text for the image. The alternative text is in the image. Displaying when it cannot be displayed also helps with accessibility.

HTML is a markup language used to build the structure and content of web pages. Adding images to web pages is one of the very common needs. Below, I will answer the code of how to add pictures in HTML in 1,500 words from a programmer's perspective.

In HTML, adding images requires the use of tags. This tag is an empty tag and does not need to be closed. Here is an example of a basic image tag:

<img src="image.jpg" alt="图片描述">

In the above code, we use the src attribute to specify the path of the image, and the alt attribute is used to provide a description of the image. Below I will explain the use of these properties and some other common properties in detail.

src attribute: This attribute is used to specify the path of the image. Paths can be relative or absolute. Relative paths are relative to the current HTML file. An absolute path is a complete URL, which can be a file path on the local file system or a file path on a remote server. For example:

Relative path: src="images/image.jpg"

Absolute path: src="https://example.com/images/image.jpg"

Note: If the image file and HTML file are in the same directory, you only need to provide the file name.

alt attribute: This attribute is used to provide alternative text for the image. Alternate text, which displays when an image cannot be displayed, also helps with accessibility. For example:

<img src="image.jpg" alt="一只可爱的猫咪">

width and height attributes: These two attributes are used to specify the width and height of the image. Can be defined using pixels (px), percentage (%), or other units. For example:

<img src="image.jpg" width="300px" height="200px">

Note: If only one of the attributes is specified, the browser will automatically calculate the value of the other attribute in a way that maintains the aspect ratio of the image.

title attribute: This attribute is used to provide the title of the image, which is displayed when the mouse is hovering over the image. For example:

<img src="image.jpg" title="这是一张美丽的风景图片">

align attribute: This attribute is used to specify the alignment of the image in the text. Can be set to left (left-aligned), right (right-aligned), or middle (center-aligned). For example:

<img src="image.jpg" align="left">

border attribute: This attribute is used to specify the border width of the picture. Can be defined using pixels (px) or other units. For example:

<img src="image.jpg" border="1px">

In addition to the above properties, there are some other properties that can be used to further control the display and behavior of the image. For example:

usemap attribute: used to specify a client-side image map to trigger specific actions when the user clicks on the image.

ismap attribute: used to specify whether the image is a server-side image mapping.

crossorigin attribute: used to specify how to handle cross-origin image requests.

loading attribute: used to specify the loading method of the image, which can be lazy (lazy loading) or eager (immediate loading).

srcset attribute: used to specify a set of alternative images. The browser will select the most appropriate image to load based on the screen size and resolution.

To summarize, by using tags and related attributes, we can easily add images in HTML. These properties can be used to control the path, size, alignment, borders, alternative text, etc. of the image. At the same time, other properties can be used to further control the behavior and loading of images. I hope this answer can help you understand the code for adding images in HTML.
