    font-family: Arial;
    background: #99DA5E;
    margin: 5px 0;
    padding: 1%;
    width: 150px;

You can use text-overflow: ellipsis; in css file. for example:

div {
font-family: Arial;
background: #99DA5E;
margin: 5px 0;
padding: 1%;
width: 150px;
overflow: hidden;
height: 17px;
color: #252525;
}
span {
float: left;
font-family: Arial;
background: #FAFA41;
margin: 5px 0;
padding: 1%;
width: 150px;
overflow: hidden;
height: 17px;
color: #505050;
}

.short-text {
    text-overflow: ellipsis;
    white-space: nowrap;
    overflow: hidden;
}

<div>apple</div>
<div>jack fruit</div>
<div class="short-text">super puper long title for fruit</div>
<div>watermelon</div>


<span class="short-text">should look like this...</span>

In order for text-overflow: ellipsis to work you must also specify a width (or a max-width), white-space: nowrap and overflow: hidden

The element must be a block so make sure to use display: block or display: inline-block on inline elements.

div {
    width: 100px;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}
