How to Get Div Height 100% Inside Td of 100%

How to make div fill td height

If you give your TD a height of 1px, then the child div would have a heighted parent to calculate it's % from. Because your contents would be larger then 1px, the td would automatically grow, as would the div. Kinda a garbage hack, but I bet it would work.

Make div height 100% in a table cell

If you only need the background color to cover the entire cell, you can just set it on the td rather than div.

td:last-child {
  background-color: green;
}

If you really need to make the div to cover the cell, you can try using the position tricks. Note, this approach only works when there is less data in the second cell.

td {
  position: relative;
}
td:last-child div {
  background-color: green;
  width:100%;
  height: 100%;
  position: absolute;
  left: 0;
  top: 0;
}

Here's another relevant SO answer

It appears you need to add a height to the <table> tag.

<table style="border-collapse: collapse; height:100%">

Firefox, IE9+ issue with div height 100% inside a td (working example on Chrome)

Try setting the height of the tr and td to 100%:

tr, td { height: 100%; }

Generally speaking to get height: 100% to work correctly, all the heights of the element's parents must be set as well.

EDIT:

An alternative solution is to wrap the contents of the td with a container div and use absolute positioning to ensure the .edit-me div effectively has 100% height.

Here's what the HTML would look like:

<table border="1">
    <tr>
        <td>
            <div class="container">
                <div class="edit-me"></div>
                Foo
                <br/>
                Bar
            </div>
        </td>
        <td>hello</td>
    </tr>
</table>

and the CSS:

.container {
    position: relative;
    padding-left: 10px;
}

.edit-me {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;

    width:10px;
    border:1px solid blue;
    background:red;
    overflow: auto;
}

Hope this helps!

Make a DIV fill an entire table cell

The following code works on IE 8, IE 8's IE 7 compatibility mode, and Chrome (not tested elsewhere):

<table style="width:100px"> <!-- Not actually necessary; just makes the example text shorter -->
   <tr><td>test</td><td>test</td></tr>
   <tr>
      <td style="padding:0;">
         <div style="height:100%; width:100%; background-color:#abc; position:relative;">
            <img style="left:90px; position:absolute;" src="../Content/Images/attachment.png"/>
            test of really long content that causes the height of the cell to increase dynamically
         </div>
      </td>
      <td>test</td>
   </tr>
</table>

You said in your original question that setting width and height to 100% didn't work, though, which makes me suspect that there is some other rule overriding it. Did you check the computed style in Chrome or Firebug to see if the width/height rules were really being applied?

Edit

How foolish I am! The div was sizing to the text, not to the td. You can fix this on Chrome by making the div display:inline-block, but it doesn't work on IE. That's proving trickier...

div will not fill height of td with height: 100%

please try:
the div will be 100%; height.

div{
    height: 100%;
    border: 1px solid;
    display:inline-block;
}

Full height div inside td

With a colon? Also, to get your spacing:

<td style="position:relative;">
    <div style="width: 10px; position:absolute; top:10px; bottom:10px; background:grey">
    </div>
</td>

EDIT:

I don't think it's possible without specifying an explicit height. The solution in the original question that you pointed to does not actually work. position:relative does not seem to apply correctly to table cells. This could well be intentional and part of the spec.

How to make div fill td height in Firefox

Try adding display: table to your nested <div>, and change height: 1px to height: 100% on the parent <td>

Example that works in Firefox, IE and Chrome

table,

th,

td {

  border: 1px solid black;

}

.fix_height {

  height: 1px;

}

@-moz-document url-prefix() {

   .fix_height {

        height: 100%;

    }

}

<table>

  <tr>

    <td class="fix_height">

      <div style="border:1px solid red; height:100%; display:inline-table">

        I want cell to be the full height

      </div>

    </td>

    <td>

      This cell

      <br/>is higher

      <br/>than the

      <br/>first one

    </td>

  </tr>
