Thoughts:

Create a mask and set the stacking order of the mask to ensure that other elements can be covered


position: absolute;
top: 0;
left: 0;
display: none;
background-color: rgba(9, 9, 9, 0.63);
width: 100%;
height: 100%;
z-index: 1000; • Set the background color and display format of the contents in the mask 
width: 50%;
text-align: center;
background: #ffffff;
border-radius: 6px;
margin: 100px auto;
line-height: 30px;
z-index: 10001; • Binding event ,  Dynamic switching mask  display  Attribute 
function showModel() {
document.getElementById('myModel').style.display = 'block';
}
function closeModel() {
document.getElementById('myModel').style.display = 'none';
}

Note: The mask should be absolutely positioned, the width and height should occupy the whole page, and the stacking order should be large
