Method to Automatically Append 'Required Field' Asterisk to Form Inputs Using CSS

It's possible to automatically append an asterisk (*) to indicate required form inputs without having to include an additional markup. One approach involves leveraging the :after CSS pseudo-element to insert the asterisk after the input elements.

However, with this approach, the asterisk gets inserted after the element content, which makes it impossible to achieve the desired result of having the asterisk appear directly after the element itself.

To overcome this limitation and attain a solution that offers the desired flexibility and functionality, consider the following approach:

CSS:

<code class="css">.required:after {
    content: " *";
    color: red;
}</code>

HTML:

<code class="html"><label class="required">Name:</label>
<input type="text"></code>

In this approach, the :after pseudo-element is applied to the .required class, which is assigned to the label element. This ensures that the asterisk appears after the label, which is the desired position for indicating that the field is required.

This solution provides the following benefits:

• Flexibility to control the position of the asterisk relative to the form input.
• Ability to handle odd cases where the form layout prevents the asterisk from appearing in the standard position.
• Works well with validation that checks the form or highlights incomplete controls.

By using this technique, you can automatically add a required field asterisk to form inputs while maintaining flexibility and avoiding additional markup.
