Limit text to the width of sibling image / auto width in CSS

Question

I am essentially trying to create a version of the \"figure\" element (upcoming in HTML5), whereby I have an image with a short description below it.

However, I want

Answer 1

This could also be accomplished using 'display: table-caption' for the caption, as follows:

HTML

<div class="wrapper">
  <img src="image.jpg" />
  <div class="caption">My caption...</div>
</div>

Stylesheet

.wrapper {
  display: table;
}

.caption {
  display: table-caption;
  caption-side: bottom;
}

This block can also be floated left of right of other text. I've tested this in IE8+. Here's a JSBin example: http://jsbin.com/xiyevovelixu/1

Answer 2

I had the same problem and after reading this decided to use an inline-style on the surrounding element. Seems the better solution over using a table to me.

Answer 3

You could use the display:table solution for all other browsers, and a CSS Behaviour for Internet Explorer.

Answer 4

Stylesheet

div.figure img,
div.figure div.caption {
    width: 100%;
}
div.figure div {
    overflow: hidden;
    white-space: nowrap;
}

note: to enable wrapping just remove that last css line

HTML

<div class="figure" style="width:150px;">
    <img src="logo.png" alt="logo" />
    <div class="caption">A description for the image</div>
</div>

I've checked it in Chrome, Firefox and IE7 and it looks good in all three. I realise this has the width on the div and not the img, but at least you only need to set the width in one place. Short of using css-expressions (IE only) I can't see a way of setting the outer divs width to the width of the first child element.

Answer 5

For setting the width to match the image automatically you could use

.figure {
  display: table;
  width: 1px;
}

This makes the div behave like a table (not supported in Internet Explorer). Or you could use a table instead of the div. I don't think there is another way of setting the width automatically.

Edit: The simplest way is to forget about the auto width and set it by hand. If it is really needed you can use JavaScript or a table. In this case the use of a table is not so ugly because you are addressing a limitation of the HTML version. In the case of server-side scripting you could also set the width when generating the page.
