Can I have an onclick effect in CSS?

Question

I have an image element that I want to change on click.

This works:

#btnLeft:hover {
    width:7         


        

Answer 1

you can use :target

or to filter by class name, use .classname:target

or filter by id name using #idname:target

#id01:target {      
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    display: flex;
    align-items: center;
    justify-content: center;
}

.msg {
    display:none;
}

.close {        
    color:white;        
    width: 2rem;
    height: 2rem;
    background-color: black;
    text-align:center;
    margin:20px;
}
