HTML truncate content based on div height

Question

I have a div with width of 130px a height of 200px.

Various text content gets displayed in this div (I\'ve written some JS to fade in and out differ

Answer 1

I used dotdotdot jQuery plugin to solve a similar problem. Line breaks should not be an issue with dotdotdot but inserted images should have width and height atributes specified in html.

If you are generating content dynamically you could determine image dimensions server-side (e.g. getimagesize function if you are using PHP). If this is not an option you can initialize dotdotdot inside $(window).load() but this will probably show content without ellipsis till all the media on the page is loaded.

Answer 2

Try this:

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

Answer 3

Try this:

.ellipsis{ 
  white-space: word;
  overflow:hidden;
}

.ellipsis:after{
  content:'...';
}

Answer 4

Here's a solution:

There's a dangling ellipsis container at the end of the text container. The ellipsis is hidden using JavaScript if the text fits the container. The <span> for the ellipsis has to have a background to occlude the original text. I used flat white in my example. You can optionally use a PNG with alpha transparency to occlude the text with a nice gradient (transparent to white).

You can optionally inject the ellipsis markup with your script to keep your original markup pristine.

It's also unfortunate that the ellipsis is right-justified instead of immediately following the last character that's displayed.

Markup:

<div class="container">
    <div class="summary">
        Your text goes here
    </div>
    <div class="ellipsis"><span>&hellip;</span></div>
</div>

Style:

.container {
    width: 200px;
    border: 1px solid #888;
    padding: 0.5em;
    line-height: 1.2em;
    margin-bottom: 10px;
}
.summary {
    height: 6em; /* adjust based on line-height * rows desired */
    overflow: hidden;
}
.ellipsis {
    height: 0;
    position: relative;
    top: -1.2em;
    text-align: right;
}
.ellipsis span {
    background: white; /* occlude text with background color */
    padding-left: 0.5em;
    position: relative;
    top: -0.25em;
}

Script:

$(".summary").each(function () {
    $(this).next().toggle(this.scrollHeight > this.offsetHeight);
});
