Increasing the size of the td element when including a new row

Here is an html page example that I am working with:

However, when I add a new row beneath the existing row that contains a div block and form within it, I notice that the td tag in the first row expands in width, as depicted in the image below.

Below is the source code for the page:

<html>
<body>
    <div style="left: 100px; position: relative; width: 400px;">
        <table>
            <tr>
                <td><label style="font-size:17px;"> Select the operation:</label></td>
                <td><select style="font-size:15px" property="" id="operation" name="operationSelection" onchange="categorySelector()">
                    <option value="addOp"> Addition </option>
                    <option value="searchOp"> Search </option>
                    <option value="listOp"> List </option>
                    <option value="updateOp"> Update </option>
                    <option value="deleteOp"> Delete </option>      
                </select></td>                           
            </tr>

            <tr>
                <td>
                    <div id="add" style="position: relative; width: 200px;">
                        <form name="addForm" action="udm_2.jsp" method="POST">
                            <table>
                                <tr>
                                    <td><label style="font-size:17px;"> Select the Gender:</label></td>       
                                </tr>
                                <tr>
                                    <td>
                                        <input type="radio" name="addCategory" value="male" checked="checked">Male<br>
                                        <input type="radio" name="addCategory" value="female">Female<br>
                                    </td>
                                </tr>
                                <tr>
                                    <td>
                                        <input type="submit"/>
                                    </td>
                                </tr>
                            </table>
                        </form>
                    </div>
                </td>
            </tr>
        </table>
    </div>
</body>
</html>

I attempted to adjust the width of the td without success. Can someone please provide an explanation for this behavior?

Answer №1

The reason for this issue is due to the presence of width: 200px; specified in the div that acts as a child of the first td element within the second tr element.

It's important to note that table cells (td) automatically adjust their width based on the longest cell in the column. Hence, setting the width of the first td element (and other elements in the same column) to 200px.

To resolve this, you can either remove the width specification from the div or relocate the select box so it is within the same td element as its label, like the following:

<td>
      <label style="font-size:17px;"> Select the operation:</label>
      <select style="font-size:15px" property="" id="operation" name="operationSelection" onchange="categorySelector()">
                <option value="addOp"> Addition </option>
                <option value="searchOp"> Search </option>
                <option value="listOp"> List </option>
                <option value="updateOp"> Update </option>
                <option value="deleteOp"> Delete </option>      
       </select></label>
    </td>   
    

If tables are not crucial for your layout, I suggest considering using divs instead. Tables are beneficial for displaying content in a tabular structure. If your case doesn't require this format, opting for divs may be a more suitable choice.

Answer №2

Using HTML table elements for styling purposes is not recommended. It's considered a bad practice. Instead, consider using other elements like divs or elements with semantic value. Also, it's advisable to keep your CSS in a separate file and use em units instead of px.

Check out this demo showcasing the use of divs.

Below is the HTML code featuring divs:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <title>Test</title>
  <meta name="description" content="">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  <link rel="stylesheet" href="path/to/your/css/styles.css">
</head>    

<body>    

<div class="wrapper">

   ...

</div>


</body>
</html>

The corresponding CSS found in styles.css:

.wrapper {
  left: 100px;
  position: relative;
  width: 400px;
}

.form-wrapper {
  position: relative;
  width: 200px;
}

.label {
  font-size: 1.1em;
}

select {
  font-size: .9em;
}
