HTML CODE
create html file named index.html , we used html comment for better explanation.
<!DOCTYPE html>
<html>
<head>
<title>login form</title> <!-- Sets the title of the webpage -->

<!-- Links an external CSS stylesheet -->
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container d-flex justify-content-center align-items-center vh-100">
<!-- Container to center content vertically and horizontally -->
<div class="card p-4 text-center" style="width: 400px;">
<!-- Bootstrap card component -->
<h2 class="mb-4">Login</h2> <!-- Heading for login -->
<form action="#" method="POST"> <!-- Form for login -->
<div class="mb-3">
<!-- Input field for username -->
<input type="text" class="form-control" placeholder="Username" required>
</div>
<div class="mb-3">
<!-- Input field for password -->
<input type="password" class="form-control" placeholder="Password" required>
</div>
<button type="submit" class="btn btn-danger rounded-pill w-100">Login</button> <!-- Submit button for login -->
</form>
</div>
</div>
</body>
</html>
CSS code
create html file named Styles.co , we used CSS comment for better explanation.
/* Applies styles to the html and body elements */
html, body {
width: 100%; /* Sets the width of the html and body elements to 100% */
height: 100%; /* Sets the height of the html and body elements to 100% */
margin: 0; /* Removes default margin */
padding: 0; /* Removes default padding */
background-color: orange; /* Sets the background color of the body to orange */
}
/* Applies additional styles to the body element */
body {
-webkit-font-smoothing: antialiased; /* Improves font rendering in WebKit-based browsers */
-moz-osx-font-smoothing: grayscale; /* Improves font rendering in Firefox on macOS */
font-family: ui-sans-serif, system-ui, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, "Noto Sans", sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; /* Specifies font family */
}
/* Applies styles to all elements, pseudo-elements, and pseudo-classes */
*,
::before,
::after {
box-sizing: border-box; /* Uses border-box model for sizing */
border-width: 0; /* Sets border width to 0 */
border-style: solid; /* Sets border style to solid */
border-color: #ffffff; /* Sets border color to white */
}
Explanation:
- The styles for
htmlandbodyelements ensure that they occupy the entire viewport with a width and height of 100%. Additionally, default margins and paddings are removed, and the background color of the body is set to orange. - Further styles are applied to the
bodyelement, including font smoothing to improve text rendering in different browsers and specifying a font family for text content. - The
*,::before, and::afterselectors apply styles to all elements, pseudo-elements, and pseudo-classes. These styles set the box-sizing model to border-box, which ensures that padding and border are included in the element’s total width and height calculations. Additionally, the border width, style, and color are set to provide a default border style across all elements.
Frequently asked question
- How do I create a basic login form in HTML?
To create a basic login form in HTML, you can use <form> elements with <input> fields for username and password, along with a submit button. You’ll also need to specify the action attribute of the form to indicate where the form data should be submitted.
- How can I style my login form using CSS?
CSS can be used to style various aspects of your login form, including colors, fonts, spacing, and layout. You can apply styles to form elements such as input fields, buttons, and labels to achieve the desired visual appearance.
- How can I make my login form responsive?
To make your login form responsive, you can use CSS techniques such as media queries to adjust the layout and styling based on different screen sizes. This ensures that your login form looks and functions well on various devices, including desktops, tablets, and mobile phones.
- What are some best practices for designing a secure login form?
Designing a secure login form involves implementing measures such as using HTTPS for secure communication, hashing passwords before storing them in the database, implementing CSRF protection, and using strong authentication mechanisms like multi-factor authentication (MFA).
- Can I add custom validation to my login form?
Yes, you can add custom validation to your login form using JavaScript. You can write JavaScript functions to validate user input, such as checking if the username and password meet certain criteria or if the fields are not empty. Additionally, HTML5 introduced form validation attributes like required and pattern which can be used for basic validation without JavaScript.
Certainly! Here are five frequently asked questions about HTML & CSS:
- What is HTML and CSS, and how do they differ?
HTML (Hypertext Markup Language) is the standard markup language used to create the structure and content of web pages. CSS (Cascading Style Sheets) is a style sheet language used to define the presentation and layout of HTML documents. HTML focuses on content, while CSS focuses on styling and design.
- What are the key elements of HTML?
HTML consists of various elements, including tags such as <html>, <head>, <body>, <div>, <p>, <img>, <a>, <table>, <form>, etc. These elements are used to structure content, create headings, paragraphs, images, links, tables, forms, and more on web pages.
- How can I center elements in CSS?
Centering elements in CSS can be achieved using various techniques such as setting margin: auto; for block-level elements, using flexbox (justify-content: center; align-items: center;), or using positioning (position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%);). The choice of technique depends on the specific layout requirements.
- What are media queries, and how are they used in CSS?
Media queries in CSS allow you to apply styles based on the characteristics of the device or viewport, such as width, height, device orientation, etc. They are commonly used for creating responsive designs that adapt to different screen sizes and devices. Media queries are written using the @media rule followed by the conditions for applying the styles.
- How can I make my website accessible and inclusive using HTML & CSS?
Accessibility in web design involves ensuring that your website is usable by people with disabilities. Techniques for improving accessibility include providing alternative text for images (alt attribute), using semantic HTML elements (<nav>, <main>, <header>, <footer>), ensuring keyboard navigation, using proper contrast ratios for text and background colors, and avoiding reliance on color alone to convey information.
