CSS marquee only displaying text as wide as the page is

My marquee is only displaying my text as wide as the screen is. I'm not sure what options I have to make it display all the text, regardless of the screen width. I know my width: 100% style is the issue here.

.example1 {
    height: 50px;
    overflow: hidden;
    position: relative;
}

.example1 h3 {
    position: absolute;
    width: auto;
    height: 100%;
    margin: 0;
    line-height: 50px;
    text-align: center;
    /* Starting position */
    -moz-transform: translateX(100%);
    -webkit-transform: translateX(100%);
    transform: translateX(100%);
    /* Apply animation to this element */
    -moz-animation: example1 15s linear infinite;
    -webkit-animation: example1 15s linear infinite;
    animation: example1 15s linear infinite;
}


/* Move it (define the animation) */

@-moz-keyframes example1 {
    0% {
        -moz-transform: translateX(100%);
    }
    100% {
        -moz-transform: translateX(-100%);
    }
}

@-webkit-keyframes example1 {
    0% {
        -webkit-transform: translateX(100%);
    }
    100% {
        -webkit-transform: translateX(-100%);
    }
}

@keyframes example1 {
    0% {
        -moz-transform: translateX(100%);
        /* Firefox bug fix */
        -webkit-transform: translateX(100%);
        /* Firefox bug fix */
        transform: translateX(100%);
    }
    100% {
        -moz-transform: translateX(-100%);
        /* Firefox bug fix */
        -webkit-transform: translateX(-100%);
        /* Firefox bug fix */
        transform: translateX(-100%);
    }
}

.example1 h3:hover {
    -moz-animation-play-state: paused;
    -webkit-animation-play-state: paused;
    animation-play-state: paused;
}

<div class="example1">
    <h3>LeBron sets tone at Cavs media day | Rajon Rondo breaks hand in fall | LeBron: Patience is key for Cavs | Jackson: Knicks can make playoffs | Grizzlies sign F Michael Beasley |
    </h3>
</div>

Solution

The problem is that your text is breaking into new lines. Add a white-space: nowrap to example1 class to fix that.

Here's the snippet:

.example1 {
    height: 50px;
    overflow: hidden;
    position: relative;
    white-space: nowrap; /* <--- FIX */
}

.example1 h3 {
    position: absolute;
    width: auto;
    height: 100%;
    margin: 0;
    line-height: 50px;
    text-align: center;
    /* Starting position */
    -moz-transform: translateX(100%);
    -webkit-transform: translateX(100%);
    transform: translateX(100%);
    /* Apply animation to this element */
    -moz-animation: example1 15s linear infinite;
    -webkit-animation: example1 15s linear infinite;
    animation: example1 15s linear infinite;
}


/* Move it (define the animation) */

@-moz-keyframes example1 {
    0% {
        -moz-transform: translateX(100%);
    }
    100% {
        -moz-transform: translateX(-100%);
    }
}

@-webkit-keyframes example1 {
    0% {
        -webkit-transform: translateX(100%);
    }
    100% {
        -webkit-transform: translateX(-100%);
    }
}

@keyframes example1 {
    0% {
        -moz-transform: translateX(100%);
        /* Firefox bug fix */
        -webkit-transform: translateX(100%);
        /* Firefox bug fix */
        transform: translateX(100%);
    }
    100% {
        -moz-transform: translateX(-100%);
        /* Firefox bug fix */
        -webkit-transform: translateX(-100%);
        /* Firefox bug fix */
        transform: translateX(-100%);
    }
}

.example1 h3:hover {
    -moz-animation-play-state: paused;
    -webkit-animation-play-state: paused;
    animation-play-state: paused;
}

<div class="example1">
    <h3>LeBron sets tone at Cavs media day | Rajon Rondo breaks hand in fall | LeBron: Patience is key for Cavs | Jackson: Knicks can make playoffs | Grizzlies sign F Michael Beasley |
    </h3>
</div>
