how can i make footer absolute i.e. at the end of content of main section and footer at the bottom of viewport display when there is lesser content in main section.I have tried with the following code please have a glance. If you donot understand my problem please ask in comment rather than giving downvote. In the below code when content in section increases footer looses its fixed position and move up. So let me know what can be done.
html{
height:100%;
box-sizing: border-box;
}
*,*:after,*:before{
box-sizing: inherit;
}
body{
position: relative;
margin: 0;
min-height: 100%;
font-family: 'Roboto', sans-serif !important;
background: #f2f2f2;
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
min-width:250px;
overflow-x:scroll
}
main{
min-height: 100%;
margin: 0;
}
footer{
position: absolute;
right: 0;
left: 0;
bottom: 0;
background: #333;
color: #fff;
text-align: center;
padding: 0 2rem;
}
