Variable-width inline underline effects in CSS

I need to simulate the look of a typical paper form in CSS. It consists of a two-column table of fields. Each field consists of a field name (of variable width) followed by an underline that continues to the end of the column. The field might be populated, in which case there is some text centered above the line, or it may be blank. If that isn't clear, he's a rough idea in manky ASCII art:

Name: _______Foo_______  Age: _____17______
Location: __Melbourne__  Handedness: _Left_

(except that the underline would continue under any text)

To implement the underline without text, I assume I should use a border-bottom rather than a text-decoration: underline. Additionally, I need the bordered element to take up the full available space. Both of those argue for a block-level element. However, I can't find any way to get the block level element (e开发者_运维知识库ither a div, an li, or a span set to display: block or inline-block) to remain on the same line as the label. As soon as I give it a width: 100%, it newlines. I've tried various combinations of floats, and I'm not inclined to do anything ridiculous with absolute positioning. Any recommendations?

I have two solutions for you. One is nice, but does not work in IE. One is ugly, but seems to work everywhere. First, the nice one, using divs and css:

<style type="text/css"> 
  .container { width:500px; }
  .field { width:240px; display:table; float:left; }
  .label { white-space:nowrap; display:table-cell; width:1px; } 
  .data { border-bottom: solid 1px black; width="100%";text-align:center; margin-left:10px; white-space:nowrap; display:table-cell; } 
  .row { display:table-row; }
</style> 

<div class="container"> 
  <div class="field"> 
    <div class="row"> 
      <div class="label">label 1</div> 
      <div class="data">data 1</div> 
    </div>
  </div>
  <div class="field"> 
    <div class="row"> 
      <div class="label">label 2</div> 
      <div class="data">data 2 </div> 
    </div>
  </div>
  <div class="field"> 
    <div class="row"> 
      <div class="label">label 3</div> 
      <div class="data">data 3 </div> 
    </div>
  </div>
  <div class="field"> 
    <div class="row"> 
      <div class="label">label 4</div> 
      <div class="data">data 4 </div> 
    </div>
  </div>
</div>

Since IE doesn't support table-cell (etc), we need an ugly one:

<style type="text/css">
  .table-field { width:240px; display:table; float:left; }
  .table-label { white-space:nowrap; } 
  html>body .table-label { width:1px; }  /* force firefox to shrink label to fit text */
  .table-data { border-bottom: solid 1px black; width="100%";text-align:center; white-space:nowrap; } 
</style> 

<div class="container"> 
  <table class="table-field"><tr><td class="table-label">label 1</td><td class="table-data">data 1</td></tr></table>
  <table class="table-field"><tr><td class="table-label">label 2</td><td class="table-data">data 2</td></tr></table>
  <table class="table-field"><tr><td class="table-label">label 3</td><td class="table-data">data 3</td></tr></table>
  <table class="table-field"><tr><td class="table-label">label 4</td><td class="table-data">data 4</td></tr></table>
  <table class="table-field"><tr><td class="table-label">label 5</td><td class="table-data">data 5</td></tr></table>
  <table class="table-field"><tr><td class="table-label">label 6</td><td class="table-data">data 6</td></tr></table>
</div>

Either way, this needs colors and margins/padding to look good.

I guess you could set the width for each element individually - I know it's not an elegant solution, but better then using javascript.

I've experimented with this a bit this evening and the following is a possibility. You can make different classes for different sizes. It's a little better than having to code the sizes individually.

Name: <hr class="fieldA" /> Email: <hr class="fieldA" />

CSS:

.fieldA {
    padding-left:120px;
    height:1px;
    display:inline-block;
    margin-bottom:0;
    color:#000000;
    backgound-color:#000000;  
}
