Placing a multiline text on an image with a white background resembling tape requires small padding on each side of the text. One way to accomplish this is by using box-shadow for the inline text.
div.slide {
background-color: black;
height:200px;
width:600px;
}
div.show {
position:absolute;
top:50px;
left:50px;
color:black;
width:200px;
}
h3 {
color:black;
background-color:white;
display:inline;
-moz-box-shadow: 5px 0px 0px white, -5px 0px 0px white;
-webkit-box-shadow: 5px 0px 0px white, -5px 0px 0px white;
box-shadow: 5px 0px 0px white, -5px 0px 0px white;
}<div class="slide">
<div class="show">
<h3>Lorem ipsum dolor sit amet, consetetur sadipscing elitr</h3>
</div>
