Place a button in relation to the top of its parent element

I am trying to display control buttons at the top of a table cell when hovering over an image within the cell. Here is the HTML structure I have:

<table id="pridat_fotky">
    <tbody>
        <tr>
            <td class="empty">
                <button>X</button>
            </td>
        </tr>
    </tbody>
</table>

To achieve this, I attempted using position:relative for the table cell and position:absolute for the button like so:

table#pridat_fotky td {
  position: relative;
}
/**THE BUTTON**/
table td button {
  position: absolute;
  top: 0px;   
  left: 50%;  
}

However, the button ended up aligning itself to the top of the window instead of the cell. You can see a proof of this in the following fiddle, where the button appears as a red square.

I found a working solution here.

Answer №1

To properly display a button within table cells, you must wrap the content with a block level element like this:

<td class="empty">
    <div><button>X</button></div>
</td>

Then, add the following CSS rule:

table#pridat_fotky td div {
    /**TO MAKE THE BUTTON APPEAR RELATIVE?**/
    position: relative;
    height: 100%;
}

Using position: relative directly on table cells is invalid, but it can be applied to block level elements inside these cells.

Make sure to set height: 100% for the div to fill the table cell properly and ensure correct placement of the button.

For a demonstration, visit: http://jsfiddle.net/audetwebdesign/k9fWN/

Note: Remember to include the wrapper div in all table cells where you wish to insert the button.

Answer №2

Your CSS contains a syntax issue. Line 17 is missing a colon, for example: (left 50%;)
