The blog on the W3Schools website explains the tag in HTML, which is used to display images on a web page. The tag has several attributes that can be used to specify the location, size, and other properties of the image.
The blog starts by explaining the basic syntax of the tag, which includes the "src" attribute that specifies the URL of the image file. It also explains the "alt" attribute, which provides a text description of the image for users who cannot see it.
Next, the blog explains how to specify the width and height of the image using the "width" and "height" attributes. These attributes can be specified in pixels or as a percentage of the width or height of the surrounding element.
The blog also discusses the "title" attribute, which is used to provide a tooltip when the user hovers over the image. This can be useful for providing additional information about the image.
Another important attribute of the tag is the "srcset" attribute, which is used to specify multiple versions of the image for different screen sizes. This can improve performance by serving smaller images to devices with smaller screens.
The blog also covers some advanced features of the tag, such as using the "srcset" attribute with the "sizes" attribute to specify different image sizes based on the viewport size. It also discusses using the "loading" attribute to control when the image is loaded.
Finally, the blog provides some best practices for using images on web pages. It recommends using descriptive file names for images, optimizing images for web use to reduce file size, and using the "alt" attribute to provide meaningful descriptions of images for users who cannot see them.
Overall, the blog provides a comprehensive overview of the tag and its various attributes. It is a useful resource for web developers who need to display images on their web pages and want to ensure they are using best practices to optimize performance and accessibility.
