I would like to display floated images with a caption underneath. But using the code below, the caption text doesn't wrap, meaning that the floated image-with-captio开发者_开发问答n takes up a huuuuuge amount of horizontal space.

If there's a better way to have an image with a caption, I'll take that over any improvements to this code. Failing that, how can I get the text inside the float to wrap?

I tried searching for this, but could only get results for wrapping text AROUND a float, not inside.

Added: I would prefer not to set an explicit width for the float, since I would have to do so for every single image I ever use.

Block-level floated elements can have a width applied to them. I would imagine that the following style should prevent the wrapping:

p.img-with-cap {
    float: left;
    width: 200px; /* or whatever */
}

If you don't want a specific width, but want it to match the width of the image, you could set the width dynamically when the window loads, like so:

function setWidth() {
    var width = document.getElementById("imgElement").width;
    document.getElementById("wrapperElement").style.width = width;
}

window.onload = setWidth;

Floated elements, just like any other block element, will take up as much width as necessary to fit their contents — up to 100%.

If you want it to be narrower than 100%, give it a width: ____; property.
