css-fullscreen background image

Generally, the home page of the login page will be made into a large background image covering the entire screen. There are many demands for this, but how to achieve compatibility has always troubled me.

For the time being, this setting is the best way I can use, but some image elements will still be lost. If there is a better way, welcome to comment.

position: fixed;
left:0;
right:0;
top: 0;
bottom: 0;
background: url('./../../assets/baseImg/home_bg.jpg') no-repeat center center fixed;
background-size:cover;
