Using CSS (Cascading Style Sheets) with HTML is quite straightforward. Here’s a basic example of how to do it:
External CSS: Create a separate .css file and link it to your HTML file using the <link> tag inside the <head> section of your HTML document.
For example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<!-- Your HTML content here -->
</body>
</html>In this case, styles.css is the name of your external CSS file.
Internal CSS: You can also include CSS styles directly within the <style> tag inside the <head> section of your HTML document.
For example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
/* Your CSS styles here */
body {
background-color: lightblue;
}
h1 {
color: darkblue;
}
</style>
</head>
<body>
<!-- Your HTML content here -->
</body>
</html>Inline CSS: You can apply styles directly to individual HTML elements using the style attribute.
For example:
<h1 style="color: red;">This is a heading</h1>
<p style="font-size: 18px;">This is a paragraph</p>Each of these methods has its use cases. External CSS is preferred for larger projects to maintain separation of concerns and improve maintainability. Internal CSS is useful for smaller projects where you want the styles to be contained within the HTML file. Inline CSS is handy for applying styles to individual elements, but it can become hard to manage in larger projects.
How to use basic CSS in HTML?
Using basic CSS in HTML involves applying styles to HTML elements to control their appearance.
Here’s a simple example of how to use CSS within an HTML document:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Basic CSS Example</title>
<style>
/* CSS code goes here */
body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
color: #333;
}
h1 {
color: #007bff;
}
p {
font-size: 16px;
line-height: 1.5;
}
.highlight {
background-color: yellow;
}
</style>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a paragraph of text. It will inherit the font family, size, and color from the body.</p>
<p class="highlight">This paragraph has a special highlight.</p>
</body>
</html>In this example:
- CSS code is embedded within the
<style>tag in the<head>section of the HTML document. - CSS rules are written to select HTML elements (
body,h1,p) and apply styles to them. - You can apply styles directly to HTML elements using their tag names, or you can use class selectors (
.highlightin this case) to apply styles to specific elements with a certain class.
This is a very basic example, but it demonstrates how to get started with CSS in HTML. You can add more styles and selectors as needed to customise the appearance of your web page.
What are the 3 types of CSS?
The three main types of CSS are:
1
Inline CSS: Styles are applied directly to individual HTML elements using the style attribute.
<p style="colour: red;">This is a paragraph with inline CSS.</p>2
Internal CSS: Styles are defined within the <style> tag in the <head> section of the HTML document. These styles apply to the entire document or specific elements within it.
For example:
<head>
<style>
p {
color: blue;
}
</style>
</head>
<body>
<p>This is a paragraph with internal CSS.</p>
</body>3
External CSS: Styles are defined in a separate .css file and linked to the HTML document using the <link> tag in the <head> section. This allows you to apply the same styles across multiple HTML pages and maintain a separation of concerns between content and presentation.
For example
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<p>This is a paragraph with external CSS.</p>
</body>And in styles.css:
p {
colour: green;
}Each type of CSS has its advantages and use cases, depending on the specific needs of your project.
What exactly does CSS do?
CSS, or Cascading Style Sheets, is a style sheet language used to describe the presentation of a document written in HTML (or XML including XML dialects such as SVG or XHTML). In simple terms, CSS determines how HTML elements are displayed on a web page.
Here’s what CSS does:
- Presentation: CSS defines the visual appearance of HTML elements. This includes properties such as colors, fonts, margins, padding, borders, and positioning. With CSS, you can control the layout, size, spacing, and other stylistic aspects of your web page content.
- Separation of Concerns: CSS separates the content of a web page (HTML) from its presentation. This separation allows developers to modify the style of a website without having to change the underlying HTML structure. It promotes cleaner code, easier maintenance, and more efficient development workflows.
- Responsive Design: CSS enables the creation of responsive web designs that adapt to different screen sizes and devices. By using techniques like media queries and flexible layouts, CSS allows developers to create websites that look good and function well on desktops, tablets, smartphones, and other devices.
- Consistency: CSS helps maintain consistency across a website by allowing developers to define styles once and apply them to multiple elements. This ensures that elements like headings, paragraphs, links, buttons, and other components have a uniform appearance throughout the site.
- Accessibility: CSS can improve the accessibility of web content by enabling developers to create designs that are easier to read and navigate for users with disabilities. For example, CSS can be used to adjust text size, contrast, and spacing to make content more accessible to users with visual impairments.
Overall, CSS plays a crucial role in web development by enhancing the visual presentation, usability, and accessibility of web pages. It allows developers to create attractive, functional, and user-friendly websites that meet the needs of both users and businesses.
What is CSS with example?
CSS, or Cascading Style Sheets, is a style sheet language used to describe the presentation of HTML (or XML) documents. It controls the layout, formatting, and appearance of elements on a web page.
Here’s a simple example to illustrate how CSS works:
HTML code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>CSS Example</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a paragraph of text.</p>
<div class="box">This is a div with class "box".</div>
</body>
</html>CSS code (styles.css):
/* Targeting all h1 elements */
h1 {
color: blue; /* Changing text color to blue */
font-family: Arial, sans-serif; /* Setting font family */
}
/* Targeting all p elements */
p {
font-size: 16px; /* Setting font size */
}
/* Targeting elements with class "box" */
.box {
background-color: yellow; /* Changing background color to yellow */
padding: 10px; /* Adding padding */
border: 1px solid black; /* Adding border */
}In this example:
- The HTML code defines the structure of the web page, including headings (
<h1>), paragraphs (<p>), and a<div>element with the class “box”. - The CSS code (defined in an external file named “styles.css”) specifies the styles to be applied to various elements:
- All
<h1>elements will have blue text colour and use the Arial font family. - All
<p>elements will have a font size of 16 pixels. - Elements with the class “box” will have a yellow background, 10 pixels of padding, and a 1-pixel black border.
- All
When the HTML document is rendered in a web browser, the CSS rules will be applied, and the elements will be displayed according to the specified styles. This separation of content (HTML) and presentation (CSS) allows for easier maintenance and customisation of web pages.
What is a CSS rule?
A CSS rule is a set of instructions that defines how HTML elements should be styled. It consists of a selector and one or more declarations.
Here’s a breakdown of the components of a CSS rule:
- Selector: The selector is used to target one or more HTML elements to which the CSS styles will be applied. It can be an element selector (e.g.,
h1,p,div), a class selector (e.g.,.my-class), an ID selector (e.g.,#my-id), or a combination of these. Selectors determine which elements on the web page will be affected by the CSS rule. - Declaration Block: The declaration block is enclosed within curly braces
{}and contains one or more declarations. Each declaration consists of a property and a value, separated by a colon (:). The property specifies the aspect of the element’s style that you want to change (e.g.,colour,font-size,background-colour), and the value specifies the new value for that property (e.g.,red,14px,#FFFFFF).
Here’s an example of a CSS rule:
/* Selector: h1 */
h1 {
/* Declaration Block */
color: blue; /* Property: color, Value: blue */
font-size: 24px; /* Property: font-size, Value: 24 pixels */
}In this example:
- Selector:
h1 - Declaration Block:
colour: blue: This rule sets the text colour of all<h1>elements to blue.font-size: 24px: This rule sets the font size of all<h1>elements to 24 pixels.
When the browser encounters this CSS rule, it will apply the specified styles to all <h1> elements in the HTML document, making the text blue and setting the font size to 24 pixels.
Is CSS still useful?
Absolutely! CSS remains an essential part of web development, and it continues to be widely used and valued for several reasons:
- Presentation and Styling: CSS is fundamental for controlling the appearance of web pages. It allows developers to define styles for text, colours, layouts, spacing, and more, ensuring a visually appealing and user-friendly experience for website visitors.
- Responsive Design: With the increasing variety of devices and screen sizes accessing the web, responsive design has become crucial. CSS provides tools like media queries and flexible layouts to create websites that adapt seamlessly to different devices, ensuring a consistent and optimized experience across desktops, tablets, and smartphones.
- Accessibility: CSS plays a vital role in improving web accessibility. By using CSS to control text size, contrast, spacing, and other visual elements, developers can make web content more accessible to users with disabilities, enhancing usability and inclusivity.
- Modularity and Maintainability: CSS promotes modularity and maintainability in web development. By separating content (HTML) from presentation (CSS) and behavior (JavaScript), developers can create cleaner, more organized codebases that are easier to update, maintain, and scale over time.
- Cross-Browser Compatibility: CSS helps ensure cross-browser compatibility, allowing web pages to render consistently across different browsers and platforms. Modern CSS features and techniques, along with tools like autoprefixer and CSS normalization, help address browser inconsistencies and improve the reliability of web layouts and styles.
- Performance Optimisation: Efficient CSS practices, such as using CSS preprocessors (e.g., Sass, Less), minification, and optimizing render-blocking resources, contribute to faster page load times and better overall performance, enhancing the user experience and search engine rankings.
- Enhanced User Experience: CSS enables developers to create engaging and interactive user interfaces with animations, transitions, and effects. These visual enhancements can captivate users, improve engagement, and elevate the overall quality of web applications and sites.
In summary, CSS remains an indispensable technology in web development, empowering developers to create attractive, accessible, and responsive websites and applications that meet the evolving needs of users and businesses.

How to write HTML code using CSS?
CSS is used to style HTML elements, but it doesn’t actually “write” HTML code. Instead, you use CSS to apply styles to HTML elements that are already written in your HTML document. Here’s a basic example of how you can use CSS to style HTML elements:
HTML code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>CSS Example</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a paragraph of text.</p>
<div id="container">
<p>This is another paragraph inside a div.</p>
</div>
</body>
</html>CSS code (styles.css):
/* Targeting the h1 element */
h1 {
color: blue; /* Changing text color to blue */
font-family: Arial, sans-serif; /* Setting font family */
}
/* Targeting all p elements */
p {
font-size: 16px; /* Setting font size to 16 pixels */
}
/* Targeting the div with id "container" */
#container {
background-color: yellow; /* Changing background color to yellow */
padding: 10px; /* Adding padding */
}In this example:
- The HTML code defines the structure of the web page, including headings (
<h1>), paragraphs (<p>), and a<div>element with the id “container”. - The CSS code (defined in an external file named “styles.css”) specifies the styles to be applied to various elements:
- The
<h1>element will have blue text colour and use the Arial font family. - All
<p>elements will have a font size of 16 pixels. - The
<div>element with the id “container” will have a yellow background and 10 pixels of padding.
- The
When the HTML document is rendered in a web browser, the CSS rules will be applied, and the elements will be displayed according to the specified styles.
What is the difference between HTML and CSS?
HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are two distinct languages used in web development, each serving a different purpose:
- HTML (Hypertext Markup Language):
- HTML is a markup language used to create the structure and content of web pages. It defines the elements and their semantic meaning within a web document.
- HTML uses tags to define different types of content, such as headings, paragraphs, lists, links, images, forms, and more.
- HTML provides the foundation for web pages, organising content into a structured format that browsers can understand and render.
- CSS (Cascading Style Sheets):
- CSS is a style sheet language used to control the presentation and appearance of HTML elements on a web page. It defines how elements should be styled, formatted, and positioned.
- CSS allows developers to specify properties such as colours, fonts, margins, padding, borders, and layouts for HTML elements.
- CSS separates the visual presentation of web content from its structural markup, enabling developers to create visually appealing and consistent designs across multiple pages.
In summary, while HTML defines the structure and content of a web page, CSS is responsible for styling and formatting that content to create visually appealing and user-friendly interfaces. HTML provides the “what” (content), while CSS provides the “how” (presentation). Together, they form the backbone of web development, allowing developers to create engaging and interactive websites for users to explore and interact with.
What is CSS in one sentence?
CSS (Cascading Style Sheets) is a style sheet language used to describe the presentation and appearance of HTML (or XML) documents on the web.
CSS can be perceived as difficult to learn for several reasons:
- Conceptual Complexity: Understanding the concepts and principles of CSS, such as selectors, inheritance, specificity, and the box model, can be challenging for beginners. CSS introduces new concepts and paradigms that may not be immediately intuitive for those who are new to web development.
- Browser Inconsistencies: Different web browsers may interpret CSS rules differently, leading to inconsistencies in how styles are applied and displayed across browsers. Dealing with browser-specific quirks and bugs can be frustrating for learners, especially when trying to create consistent designs.
- Layout Challenges: Achieving complex layouts and designs with CSS, especially without the use of frameworks or preprocessor tools, can be difficult. CSS layout techniques like floats, positioning, flexbox, and CSS Grid require practice and experimentation to master effectively.
- Specificity and Cascading: Understanding how CSS rules cascade and override each other, as well as the concept of specificity, can be confusing for beginners. Managing the priority of styles and troubleshooting conflicts can be challenging, especially in larger projects with multiple CSS files.
- Responsive Design: Creating responsive layouts that adapt to different screen sizes and devices requires an understanding of media queries, viewport units, and other responsive design techniques. Implementing responsive designs effectively can add complexity to CSS development.
- Dynamic Styling: Integrating CSS with dynamic content generated by JavaScript frameworks or content management systems (CMS) can introduce additional complexity. Managing dynamic styles, animations, and transitions may require advanced CSS knowledge and JavaScript skills.
- Lack of Immediate Feedback: Unlike programming languages where code execution results are immediately visible, CSS changes often require page refreshes or manual inspection in a web browser, making it harder to debug and troubleshoot.
Despite these challenges, with patience, practice, and the right resources, CSS can be learned effectively. Breaking down concepts into smaller, manageable chunks, experimenting with code, and seeking out tutorials, documentation, and community support can help learners overcome the difficulties associated with learning CSS.
