html image size settings

In web design, pictures are often used to increase the visual effect and appeal of the page. However, if the image size is set improperly, it will affect the appearance and loading speed of the web page. Therefore, when using pictures, pay attention to the size settings of the pictures. This article will introduce how to set the size of images in HTML.

There are two ways to set the image size in HTML:

1. Use CSS to set the image size
2. Set the image size directly in HTML

Use CSS to set the image size

There are two methods to use CSS to set the image size:

Method 1: Modify the image size by setting the CSS properties width and height.

For example, the following code demonstrates how to set the image size to 100 pixels wide and 80 pixels high.

<style>
img {
  width: 100px;
  height: 80px;
}
</style>
<img src="image.jpg">

Note:

• The set image size may be distorted because the width and height are not synchronized. When setting width or height, it is best to set another attribute at the same time to maintain the original proportions of the image.
• To reduce or enlarge the image proportionally, you can use percentage, for example, width: 50%.

Method 2: Limit the maximum image size by setting the CSS properties max-width and max-height, and the image will automatically shrink to fit within the limit.

For example, the following code will limit the image size to a maximum width of 200 pixels and a maximum height of 150 pixels.

<style>
img {
  max-width: 200px;
  max-height: 150px;
}
</style>
<img src="image.jpg">

Note:

• The image maintains its original proportions within the limit.

Set the image size directly in HTML

Another method is to set the image size directly in the HTML tag. HTML provides width and height attributes to set the image size.

For example, the following code sets the image size to a width of 100 pixels and a height of 80 pixels:

<img src="image.jpg" width="100" height="80">

Note:

• Setting the image in HTML Size affects image quality because it only shrinks the image and does not change the resolution of the image. Therefore, if you want to publish high-quality images on your website or blog, use appropriate image editing software to process and compress them.

Summary

Using CSS or HTML tags to set image sizes are both good choices, depending on your design requirements and the structure of the web page. Although these methods will affect the visual effect of the image and the speed of the page, correct use can improve the user experience and page performance. When setting the image size, try to choose an appropriate method and don't make your website visitors wait for too long.
