Align element to bottom of HTML Table Cell

Question

I have multiple elements in a cell of an HTML table. I want some of the elements to be aligned to the bottom of the cell and some to be aligned at the top. I am having trouble getting the elements to align to the bottom. My table is:

    <tr>
        <td style="background-color: #007CE2">
            <p id="t1_list">test<br>another<br>testing</p>
            <input type="text" name="t1_input" id="t1_input">
            <button>
                Add
            </button>
        </td>
        <td style="background-color: #E54040">
            <p id="t2_list"></p>
            <div class="value_input2">
                <input type="text" name="t2_input" id="t2_input">
                <button>
                    Add
                </button>
            </div>
        </td>
    </tr>

However the elements within the div seem to want to stay centered in the cell, rather than stay at the bottom. I have tried two different methods so far with CSS:

div.value_input {
    position: absolute;
    bottom: 0;
}

which just takes the div down to the bottom of the page. And:

div.value_input2 {
    display: table-cell;
    vertical-align: bottom;
}

Which has no effect.

I have the code here in JSFiddle

What do I need to do to get the input box and button to align to the bottom of the cell?

Answer 1

You need height:somepx for vertical align to work in this.

Answer 2

Make the table cell position: relative, and then you can try position: absolute on the div again...

table tr td {
  position: relative;
}

div.value_input2 {
  position: absolute;
  bottom: 0;
}

Answer 3

You need to set the parent elements position to relative position:relative in order to use absolute positioning. Here is a working snippet.

table {
    		border-collapse: collapse;
		}

		table, th, td {
		    border: 2px solid black;
        position:relative;
		}

		div.value_input {
			position: absolute;
      bottom: 0;
		}
    
    div.value_input2 {
      position:absolute;
      bottom:0;
    }

<table>
		<tr>
			<th style="background-color: #007CE2">
				Test
			</th>
			<th style="background-color: #E54040">
				Test
			</th>
		</tr>
		<tr>
			<td style="background-color: #007CE2">
				<p id="t1_list">test<br>another<br>testing</p>
				<input type="text" name="t1_input" id="t1_input">
				<button>
					Add
				</button>
			</td>
			<td style="background-color: #E54040">
				<p id="t2_list"></p>
				<div class="value_input2">
					<input type="text" name="t2_input" id="t2_input">
					<button>
						Add
					</button>
				</div>
			</td>
		</tr>

		<tr>
			<th style="background-color: #8BC34A">
				Test
			</th>
			<th style="background-color: #FF9800">
				Test
			</th>
		</tr>
		<tr>
			<td style="background-color: #8BC34A">
				<p id="t3_list"></p>
				<input type="text" name="t3_input" id="t3_input">
				<button>
					Add
				</button>
			</td>
			<td style="background-color: #FF9800">
				<p id="t4_list"></p>
				<input type="text" name="t4_input" id="t4_input">
				<button>
					Add
				</button>
			</td>
		</tr>
