Tips for maintaining a consistent height for elements in HTML

As the content of td increases, the height of th also increases. How can we ensure a fixed height for th.

This is the HTML code:

<table id="depts">
    <tr>
        <th>Topic Title</th>
        <th><a href="create.php?id=1">ADD TOPIC</a></th>
        <th>Posted By</th>
    </tr>
    <tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer.Lorem ipsum dolor sit amet, consectetuerLorem ipsum dolor sit amet, consectetuer</td>
        <td>Lorem ipsum </td>
    </tr>
    <tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer  </td>
        <td>Lorem ipsum </td>
    </tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer  </td>
        <td>Lorem ipsum </td>
    <tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer  </td>
        <td>Lorem ipsum </td>
    </tr>
</table>

Here is the CSS code:

    #depts {
        width: 500px;
        border-spacing: 0;
    }
    #depts a {
        text-decoration: none;
        color: white;
        background-color: blue;
        padding: 10px;      
    }
    #depts th {
        border-top: 1px solid black;    
        background-color: #009688;
        text-align: left;
        color: white;
        padding: 5px;
    }
    #depts th:first-child {
        border-left: 1px solid black;
        border-top-left-radius: 5px;
    }
    #depts th:last-child {
        border-right: 1px solid black;
        border-top-right-radius: 5px;
    }
    #depts td {
        border: 1px solid black;
    }

When the content in td spans only one line, the output looks like this: https://i.sstatic.net/5hK64.png

However, when there are multiple lines of content in td, the output changes to: https://i.sstatic.net/e7jzf.png

The desired output should look like this:

Answer №1

To achieve the desired result, make sure to apply position: absolute; to the Add Topic button.

    #depts a {
    text-decoration: none;
    color: white;
    background-color: blue;
    padding: 20px 10px; 
    position: absolute;
    top: -6px; right: 150px;
    width: 90px;
    }

https://jsfiddle.net/p8y4nm2k/ Similar to this approach. While not flawless, using a table layout can help maintain border consistency when breaking them is necessary.


Additionally, in a table structure, consider adding a ghost column to support proper positioning with styles like position: absolute (especially if your website is responsive).

Answer №2

To properly structure your table, make sure to use th elements within the thead tag for table headers and td tags within the tbody tag for table body content:

<table id="depts">
    <thead>
        <tr>
            <th>Topic Title</th>
            <th><a href="create.php?id=1">ADD TOPIC</a></th>
            <th>Posted By</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td colspan="2">Lorem ipsum dolor sit amet, consectetuer.Lorem ipsum dolor sit amet, consectetuerLorem ipsum dolor sit amet, consectetuer</td>
            <td>Lorem ipsum </td>
        </tr>
        <tr>
            <td colspan="2">Lorem ipsum dolor sit amet, consectetuer  </td>
            <td>Lorem ipsum </td>
        </tr>
            <td colspan="2">Lorem ipsum dolor sit amet, consectetuer  </td>
            <td>Lorem ipsum </td>
        <tr>
            <td colspan="2">Lorem ipsum dolor sit amet, consectetuer  </td>
            <td>Lorem ipsum </td>
        </tr>
    </tbody>
</table>

The thead tag defines the table header, while the tbody tag is used for the main table content.

Additionally, you can employ the tfoot tag for creating a table footer section.

I hope this explanation clears things up!

Answer №3

To ensure proper formatting, consider using "table-layout:fixed;" in your inline css or within the main stylesheet. Without this setting, text or images may spill over into adjacent columns if the width is too narrow. Avoid inserting lengthy blocks of text or phrases without proper spacing.

Answer №4

Here is a suggested addition:

#depts th {
   height: 50px;
}

CODE

<!DOCTYPE html>
<html>
<head>
<style>
    #depts {
        width: 500px;
        border-spacing: 0;
    }

    #depts a {
        text-decoration: none;
        color: white;
        background-color: blue;
        padding: 10px;
    }

    #depts th {
        border-top: 1px solid black;
        background-color: #009688;
        text-align: left;
        color: white;
        padding: 5px;
    }

    #depts th:first-child {
        border-left: 1px solid black;
        border-top-left-radius: 5px;
    }

    #depts th:last-child {
        border-right: 1px solid black;
        border-top-right-radius: 5px;
    }

    #depts td {
        border: 1px solid black;
    }

    #depts th {
        height: 50px;
    }
</style>

<table id="depts">
    <tr>
        <th>Topic Title</th>
        <th><a href="create.php?id=1">ADD TOPIC</a></th>
        <th>Posted By</th>
    </tr>
    <tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer </td>
        <td>Lorem ipsum </td>
    </tr>
    <tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer </td>
        <td>Lorem ipsum </td>
    </tr>
    <td colspan="2">Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer </td>
    <td>Lorem ipsum </td>
    <tr>
        <td colspan="2">Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer Lorem ipsum dolor sit amet, consectetuer </td>
        <td>Lorem ipsum </td>
    </tr>
</table>

Answer №5

After experimenting with different solutions, I found that setting the width of th to 33% was effective. Here is the code that worked:

    #depts th {
        border-top: 1px solid black;    
        background-color: #009688;
        text-align: left;
        color: white;
        padding: 5px;
        width: 33%;
    }

Answer №6

The reason for this is that the a element is styled as inline instead of block.

For more information, check out: http://www.w3schools.com/html/html_blocks.asp

-

If you prefer, you can easily change it to a block element and float it to the right.

Here is the original code snippet: https://jsfiddle.net/m52mv11x/

And here is the modified version with the added line: display: block; float: right;:

#depts a {
    text-decoration: none;
    color: white;
    background-color: blue;
    padding: 10px;      

    /*This is the extra line*/
    display: block; float: right;
}

Alternatively, you can include height: 40px; in #depts th, like shown here: https://jsfiddle.net/2raes3dc/
