Fading out text at bottom of a section with transparent div, but height stays under section after overlaying div

Question

I\'m trying to get a nice fade-out effect at the bottom of a section of text as a \'read more\' indicator.

I\'ve been following a bit off this and other tutorials,

Answer 1

A relatively position element is not removed from the normal html flow, so if you move it around the initial space reserved for it still remains, however with absolute positioning this is not the case

.fadeout {
    position: absolute; 
    bottom: 0em;
    width:100%;
    height: 4em;
    background: -webkit-linear-gradient(
        rgba(255, 255, 255, 0) 0%,
        rgba(255, 255, 255, 1) 100%
    ); 
    background-image: -moz-linear-gradient(
        rgba(255, 255, 255, 0) 0%,
        rgba(255, 255, 255, 1) 100%
    );
    background-image: -o-linear-gradient(
        rgba(255, 255, 255, 0) 0%,
        rgba(255, 255, 255, 1) 100%
    );
    background-image: linear-gradient(
        rgba(255, 255, 255, 0) 0%,
        rgba(255, 255, 255, 1) 100%
    );
    background-image: -ms-linear-gradient(
        rgba(255, 255, 255, 0) 0%,
        rgba(255, 255, 255, 1) 100%
    );
} 
section {position:relative}
