Text over top of image scrolling left and right - html

Question

I am trying to create a rollover effect image with CSS. The image starts with just a title overlaid, then when hovered over a text overlay appears. I am happy with how it is going so far, except the text area that comes over the top the text runs off to the right. Also you can scroll up and down, but i am assuming this is the same problem?

If you're not supporting IE7 and lower, try adding a box-sizing: border-box; property to your .service-overbox rule. It looks like it's the legacy box-model's handling of padding that is tripping you up.
.service-box .overtext {
-webkit-transition: all 300ms ease-out;
-moz-transition: all 300ms ease-out;
-o-transition: all 300ms ease-out;
-ms-transition: all 300ms ease-out;
transition: all 300ms ease-out;
transform: translateY(40px);
-webkit-transform: translateY(40px);
}
.service-box .title {
text-align: center;
opacity: 0;
transition-delay: 0.1s;
transition-duration: 0.2s;
}
.service-box:hover .title,
.service-box:focus .title {
opacity: 1;
transform: translateY(0px);
-webkit-transform: translateY(0px);
}
.service-box .tagline {
text-align: center;
opacity: 0;
transition-delay: 0.2s;
transition-duration: 0.2s;
}
.service-box:hover .tagline,
.service-box:focus .tagline {
opacity: 1;
transform: translateX(0px);
-webkit-transform: translateX(0px);
}
.service-overbox {
