How to Add a Percentage Symbol in an Editable Text Box using CSS

If you've ever wanted to display a percentage in a text box where users can freely edit the number, but you want to lock the % symbol at the end, you're not alone. This is a common requirement in forms where precise input on values is essential while maintaining a user-friendly design. In this guide, we will show you how to achieve this effect using simple HTML and CSS techniques.

The Challenge

The goal is to create a text box that allows users to type in a percentage value while ensuring that the % symbol remains at the end of the input but remains uneditable. This means we need a solution that visually appears as if the symbol is part of the input but is not included in the actual editable text field.

The Solution

We can achieve this stunning effect using CSS, particularly with a handy feature called the :after pseudo-element. Below, we’ll guide you through the implementation step-by-step.

Step 1: HTML Structure

Start by crafting the HTML structure of your text box. You simply need a div that acts as a container for an input field:

Step 2: CSS Styling

Next, we will define the CSS to add the % symbol after the input. Here’s how this can be done.

Breakdown of the CSS Code

:after Pseudo-Element:

This allows us to insert content after the specified element. We're using it to add the % symbol next to the input box.

content: "\0025"; is the Unicode representation for the % symbol.

Margins and Padding:

margin-left and margin-right help position the symbol correctly by adjusting the space around it.

padding-left makes sure there is a clear gap between the input text and the % symbol for better visibility.

Input Padding:

By applying padding-right to the input, we ensure that the text doesn't overlap with the % symbol.

Step 3: Final Integration

Now, integrate the HTML and CSS together in your project. Ensure your webpage includes a <style> section for the CSS and the HTML codes wherever you want the input box to appear.

Example Implementation

Putting it all together, your complete setup will look like this:

Conclusion

By using the :after pseudo-element in CSS, we can easily keep the % symbol fixed at the end of an editable text box, creating a cleaner interface and better user experience. This method is efficient, requires minimal code, and should work seamlessly across modern web browsers.

Implement this technique in your web applications to enhance your forms, and watch how it simplifies data entry for your users! Happy coding!
