Question

CSS code for a table cell with a border applied to it

table {
        border-collapse: collapse;
        margin:100px auto;
    }
    
 td {
        margin: 0px;
        padding: 5px;
        text-align: left;
        border:1px solid #080808;
    }
    
.border {
        border: 1px solid #080808;
    }

    
.noborders td {
        border:0;
    }

      
.border_single {

        border: 1px solid #080808;
    }

<table>
    <tbody class="border">
        <tr>
            <td>Table Cell with borders</td>
            <td>Table Cell with borders</td>
            <td>Table Cell with borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td class="border_single">Table WITH border</td>
            <td>Table Cell without borders</td>
        </tr>
    </tbody>
</table>

In order to gain a deeper understanding of how CSS values are inherited throughout the hierarchy of a table, I intentionally labeled a td as "border_single" to define and apply a basic border. However, the border is not displaying, which leads me to believe that it may be inheriting styles from higher levels causing the specific td's border not to show.

Answer №1

Your solution is accurate, just remember to include td in your class

.border_single 
{
   border: 1px solid #080808;
}

change it to this

td.border_single 
{
   border: 1px solid #080808;
}

Even if you have td.no_borders,td.with_background, and other classes, the style for td.border_single will still apply as intended. You can also use id #border_single or td#border_single for more specificity.

You can achieve similar results using td:nth-child(n), td:first-child, td:last-child without the need for ids or classes

table {
        border-collapse: collapse;
        margin:100px auto;
    }
    
 td {
        margin: 0px;
        padding: 5px;
        text-align: left;
        border:1px solid #080808;
    }
    
.border {
        border: 1px solid #080808;
    }

    
.noborders td {
        border:0;
    }

      
td.border_single {

        border: 1px solid #080808;
    }
    
tr:nth-child(5) > td:nth-child(2)
    {
    border: 1px solid #080808;
    }
tr:last-child > td:nth-child(2)
    {
    border: 1px solid #080808;
    }

<table>
    <tbody class="border">
        <tr>
            <td>Table Cell with borders</td>
            <td>Table Cell with borders</td>
            <td>Table Cell with borders</td>

            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">

            <td class="border_single">Table WITH border</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td>With border using tr:nth-child(n) > td:nth-child(n)</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td>With border using tr:last-child > td:nth-child(n)</td>
            <td>Table Cell without borders</td>
        </tr>

Answer №2

Importance of Specificity in CSS

In the world of CSS, specificity plays a crucial role in determining which styles take precedence.

The order of importance for selectors is as follows:

Importance (using !important)
Specificity
Source order

For more information on this topic, check out this link.

Consider the scenario where .no_borders td has higher specificity than .border_single:

    <tr class="noborders">
        <td>Table Cell without borders</td>
        <td class="border_single">Table WITH border</td>
        <td>Table Cell without borders</td>
    </tr>

In this case,

<td class="border_single">Table WITH border</td>

will inherit the styling from .no_borders td rather than .border_single.

A Solution: Using IDs for Increased Specificity

To tackle specificity issues, one feasible solution involves utilizing id selectors instead of class selectors since IDs have a higher level of specificity.

To implement this fix, replace .border_single with #border_single in your CSS file and use <td id="border_single"> in your HTML file. You can test this approach by running the snippet provided below.

table {
        border-collapse: collapse;
        margin:100px auto;
    }
    
 td {
        margin: 0px;
        padding: 5px;
        text-align: left;
        border:1px solid #080808;
    }

.border {
        border: 1px solid #080808;
    }

.noborders td {
        border:0;
    }
      
#border_single {
        border: 1px solid #080808;
    }

<table>
    <tbody class="border">
        <tr>
            <td>Table Cell with borders</td>
            <td>Table Cell with borders</td>
            <td>Table Cell with borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
            <td>Table Cell without borders</td>
        </tr>
        <tr class="noborders">
            <td>Table Cell without borders</td>
            <td id="border_single">Table WITH border</td>
            <td>Table Cell without borders</td>
        </tr>
