Styling a Button Inside an Input Element

Placing a button within an input element requires careful consideration to ensure proper functionality and accessibility. Modern CSS provides a flexible solution that allows for this design.

Using a flexbox layout, we can arrange the input and button horizontally within the container (e.g., a form). The input should be given ample space to grow (flex-grow), while the button can remain as a fixed size.

To present the button within the input's boundaries, we remove the border from the input, making it visually appear as part of the container's border. This allows the input to function normally without any text obstructing the button.

As the input gains focus, we move the outline to the container itself. This ensures that the focus indication encompasses both the input and button, improving accessibility and visual consistency. Adding styling to the button and container further enhances the design.

By employing a flexbox and manipulating the outline, we can seamlessly integrate a button within an input element while preserving user interaction, accessibility, and styling options.
