percentage width in css not working

Question

I was using a way to define my width property in css with the viewport measurement, css code:

#content {
    position: absolute;
    background-color: white;
    width: 100vw;
    top: 115px;
    bottom: 30px;
    display: table;
    z-index: 0;
}

When I changed the width from width: 100vw; to width: 100%; my code ain't working anymore. I want to change to percentage measurement since I discovered viewport will not work on Android < 4.4

            <td class="beschrijving" width="15%" rowspan="1" align="right">21 aug</td>
          </tr>

    border-top-width: 0px;

}

Make the positions relative instead of absolute , then width:100% should work

#mainslide {
    position: relative;
    left:100%
    z-index: 1;
}
#aanbod {
    position: relative;
    left: 0px;
}
.tablestyleorchideeaanbod {
    width: 100%;
    padding: 12px;
    padding-left: 8%;
    padding-right: 8%;
    border-bottom-width: 1px;
    border-top-width: 0px;
    border-left-width: 0px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #8cca49;
}
#content {
    position: absolute;
    background-color: white;
    width: 100%;
    top: 115px;
    bottom: 30px;
    display: table;
    z-index: 0;
}
