An alternative to using negative margin?

I am using negative margin's to place my image on the background however when i zoom to much it shifts and distorts the image to a great deal. On zooming the box on the right goes towards the top because of the negative margin.

Please find below the code i am using:-

  <div class="platform-row" style="float: right; margin-right: 145px; padding: 2px;">
            <span><a href="download/index.html">
                <img src="assets/Box.png" border="0" /></a></span><br>
            <div class="platform-row-box">
                SOME TEXT GOES HERE...................
            </div>

            <a href="download/index.html">
                <div class="getmxit">Get ABC Now</div>
            </a>
            <div style="background: black; margin-top: 3px; width: 181px; opacity: .8; padding: 2px">

                <span><a class="platform-icon apple" href="download/ios/index.html"></a></span>
                <span><a class="platform-icon android" href="download/android/index.html"></a></span>

            </div>
        </div>

CSS:

    .platform-row {
    -webkit-transform: translateZ(0);
    -moz-transform: translateZ(0);
    -ms-transform: translateZ(0);
    -o-transform: translateZ(0);
    transform: translateZ(0);
    margin-top: -530px;
    margin-left: 700px;
}

    .platform-row .platform-row-box {
        color: white;
        font-size: 14px;
        margin: 0 auto;
        width: 181px;
        opacity: .8;
        margin-top: -170px;
        position: fixed;
    }

@media screen and (max-width: 640px) {
    .platform-row {
        padding-right: 55%;
    }
}

@media screen and (max-width: 479px) {
    .platform-row {
        margin-top: 40px;
        padding-right: 35%;
    }
}

.platform-icon {
    -webkit-transition: opacity 0.2s;
    -moz-transition: opacity 0.2s;
    transition: opacity 0.2s;
    /**background-image: url("platform_icons-14a66f5cbf10a328f7b38e6070c26e62.png");**/
    background-image: url("Home_Get.png");
    display: inline-block;
    height: 25px;
    width: 25px;
    margin-right: 0px;
    opacity: 1;
}

@media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and (min--moz-device-pixel-ratio: 2), only screen and (-o-min-device-pixel-ratio: 2 / 1), only screen and (min-device-pixel-ratio: 2), only screen and (min-resolution: 192dpi), only screen and (min-resolution: 2dppx) {
    .platform-icon {
        background-image: url("platform_icons%402x-dfed2cc115fa8b344e08c9072408095a.png");
        background-size: 454px 88px;
        -webkit-background-size: 454px 88px;
    }
}

EDIT:

This is what happens when i zoom in too much because of the negative margin.
