How to set background image using html? _html/css_WEB-ITnose

When I write a web page in HTML, when I set the background image, it seems that the image is too big and cannot be displayed in full. What should I do if I want all the images to be displayed?
What if you want to add a slider? Thanks for the help!

Use the width and height attributes to control it. You can find it by checking the attributes.

Make the background layer bigger and the size is the same as the picture.

Use background for the background image. -image
