How do I style a focused input field using CSS?

Styling a focused input field using CSS allows you to change the appearance of the input element when it is selected or receives focus. This helps to provide visual feedback to users, indicating which input field they are currently interacting with. There are several ways to achieve this effect in CSS. One common approach is to use the:focus pseudo-class, which targets an element when it is in focus. You can apply various CSS properties to the input element to modify its appearance when it is focused. Here's an example of how you can style a focused input field:

1
2
3
4
5
put:focus {
  border: 2px solid blue;
  background-color: lightblue;
  color: black;
}

In the above example, when an input element receives focus, it will have a 2-pixel solid blue border, a light blue background color, and black text color. You can customize these styles according to your design preferences. Apart from border, background color, and text color, you can apply other CSS properties to modify the appearance of a focused input field. Some commonly used properties includeoutline,box-shadow, andtransition. Theoutline property allows you to add an outline around the focused input field. For example:

1
2
3
put:focus {
  outline: 2px solid blue;
}

Thebox-shadow property lets you add a shadow effect to the input field when it is focused. Here's an example:

1
2
3
put:focus {
  box-shadow: 0 0 5px rgba(0, 0, 255, 0.5);
}

Thetransition property enables you to add smooth transitions or animations when the input field receives focus. For instance:

1
2
3
4
5
6
7
put {
  transition: border-color 0.3s ease;
}

input:focus {
  border-color: blue;
}

In the above example, when the input field receives focus, the border color smoothly transitions to blue over a duration of 0.3 seconds with an ease timing function. It's important to note that different browsers may have their own default styles for focused input fields, which can vary. To ensure consistency, you can use CSS resets or explicitly define the styles for focused inputs using the:focus pseudo-class. By leveraging CSS and the:focus pseudo-class, you can easily style focused input fields to enhance the user experience and provide visual cues when users interact with form elements on your website. Remember to test your styles across different browsers to ensure consistent behavior and appearance.
