I'm struggling to implement my image button webpage. I can't seem to properly align three buttons at the bottom of the page.
.fullwidth {
width: 100%;
height: 80%;
margin-left: 0;
margin-right: 0;
padding-left: 0;
padding-right: 0;
display: block;
text-align: center;
}
.tierwidth {
width: 33.333333333333%;
height: 20%;
margin-left: 0;
margin-right: 0;
padding-left: 0;
padding-right: 0;
display: block;
text-align: center;
}
html,
body {
height: 100%;
}
#footer {
position: fixed;
bottom: 0;
width: 100%;
height: 20%;
}
.btnContainer {
float: left;
}
