css - shrink a parent div to fit one child's width and constrain the width of the other child [duplicate]

Answer 1

If you're willing to use a little javascript (jQuery in this example), you could set the width of the text div with the width of the image div.

Try adding $("#child2").css({'width': $('#child1').width()}); to the end of the JS in your fiddle, or check out the fork here: http://jsfiddle.net/VXEMu/

Answer 2

See this edited version of your jsFiddle.

Here's what's added to the CSS:

#container {
    display: table-cell;
}
#child1 {
    display: table-row;
    width: 1px;
}
#child2 {
    display: table-cell;
    width: 1px;
}

Answer 3

The answer provided by @Chris leads me to the following, great solution of my case, where I need to fit the container div only to the first child element (and leave the rest child elements to auto fit to the container's width):

div.container {
    width: fit-content;
    max-width: 100%;
    margin: 16px auto;
    display: table;
}

div.inner-primary {
    display: block;
}

div.inner-rest {
    margin-top: 8px;
    display: table-caption;
    caption-side: bottom;
}

<div class="container">
  <div class="inner-primary"><div style="width:200px; border:1px dotted #ccc; border-radius:4px; padding: 4px;">This is the main element that drives the width of the container.</div></div>
  <div class="inner-rest">This is the first of the rest divs that fit automatically to the container...</div>
  <div class="inner-rest">This is the second element...</div>
</div>
