如何获取锚标记以填充表格单元格的宽度？

Question

I have a table cell with an anchor tag and I want the width (and height) of the anchor tag to fill the width of the containing table cell. Intuition doesn't seem to work on this. Please help.

HTML:

<table>
    <tr>
        <td class="width_is_100px">
            <a href="http://www.doesnotwork.com"><span class="make_width_100px">Some Text</span></a>
        </td>
    </tr>
</table>

CSS: (doesn't work)

.make_width_100px {
    width:100px !important;
}

The anchor tag is only as wide as the text "Some Text". I want the user to be able to click anywhere inside the table cell and trigger the link. No javascript please.

Answer 1

Try it:

a {
    display: block;
    height: 100%;        
    width: 100%;
}

Answer 2

Make your <a> element a block element (it's inline by default):

.width_is_100px a {
    display:block;
}

Answer 3

None of these answers work properly to fill the width and height when the text wraps .

The only answer I found that produces a proper result filling the height and width of the cell right to the edges is this one :

td {
    overflow: hidden;
}

td > a {
    display: block;
    margin: -10em;
    padding: 10em;
}

Answer 4

<table>
    <tr>
        <td class="width_is_100px">
            <a href="http://www.doesnotwork.com"><div style="width:100%;">Some Text</div></a>
        </td>
    </tr>
</table>

Answer 5

this is probably too late but, this worked for me in tables with different content height.

html

<table class="example">
    <tr>
        <td><a href="">small content</a></td>
        <td><a href="">multiline<br>content</a></td>
    <tr>
</table>

css

table{ 
    padding:10px;  /*for example*/
}
table.example td{
    overflow:hidden;
    padding:0px; /*you can need !important*/
}
table.example a{
    display: block;
    height: 100%;
    width: 100%;
    padding: 10px 10px 500px 10px; /*table default padding except on bottom 500px for example*/
    margin-bottom: -490px; /*same as bottom padding - table padding*/
}
