Introduction

CSS (Cascading Style Sheets) is used to enhance the appearance and layout of HTML forms, making them more visually appealing and user-friendly. CSS properties can be applied to various elements within forms, such as input fields, labels, buttons, and form containers, to customize their appearance, alignment, spacing, and behavior. Here are key points about CSS forms:

Styling Input Fields:
- CSS can be used to style input fields (e.g., text fields, checkboxes, radio buttons, dropdown menus) to match the design of the website. Properties like border, background-color, padding, font-size, and border-radius can be applied to input elements to customize their appearance.
Customizing Labels:
- Labels associated with form elements can be styled using CSS to improve readability and alignment. Properties like color, font-weight, text-transform, and margin can be used to customize label appearance and position relative to input fields.
Layout and Alignment:
- CSS can control the layout and alignment of form elements within the form container. Techniques like flexbox or grid layout can be used to create responsive and visually pleasing form layouts, ensuring consistency across different devices and screen sizes.
Pseudo-classes for Interaction:
- CSS pseudo-classes can be applied to form elements to style them based on user interaction. For example, :hover can be used to change the appearance of buttons or input fields when hovered over, while :focus can be used to style elements that have keyboard focus.
Validation and Feedback:
- CSS can be used to style form elements based on their validation status or user input. For example, :valid and :invalid pseudo-classes can be used to style input fields based on whether their content meets validation criteria, providing visual feedback to users.

Focused Inputs in CSS Forms

By default, some browsers will add a blue outline around the input when it gets focus (clicked on). You can remove this behavior by adding outline: none; to the input.

<!DOCTYPE html>
<html>
<head>
<style> 
input[type=text] {
  width: 100%;
  padding: 12px 20px;
  margin: 8px 0;
  box-sizing: border-box;
  border: 1px solid #555;
  outline: none;
}

input[type=text]:focus {
  background-color: lightblue;
}
</style>
</head>
<body>

<h2>Input fields with color on :focus</h2>

<form>
  <label for="fname">First Name</label>
  <input type="text" id="fname" name="fname" value="John">
  <label for="lname">Last Name</label>
  <input type="text" id="lname" name="lname" value="Doe">
</form>

Input with Icon/Image

If you want an icon inside the input, use the background-image property and position it with the background-position property.

input[type=text] {
  width: 100%;
  box-sizing: border-box;
  border: 2px solid #ccc;
  border-radius: 4px;
  font-size: 16px;
  background-color: white;
  background-image: url('searchicon.png');
  background-position: 10px 10px; 
  background-repeat: no-repeat;
  padding: 12px 20px 12px 40px;
}
