Fundamental Concepts#

HTML Basics#

HTML is the standard markup language for creating web pages. It uses tags to structure content on a page. For example, the <html> tag is the root tag of an HTML document, and it encloses all other HTML elements. The <head> tag contains meta-information about the document, such as the page title, while the <body> tag holds the visible content of the page.

<!DOCTYPE html>
<html>
<head>
    <title>My First HTML Page</title>
</head>
<body>
    <h1>Welcome to my page</h1>
    <p>This is a simple paragraph.</p>
</body>
</html>

CSS Basics#

CSS is used to style HTML elements. It allows you to control the layout, colors, fonts, and other visual aspects of a web page. CSS rules consist of a selector and a declaration block. The selector targets an HTML element, and the declaration block contains one or more property-value pairs.

h1 {
    color: blue;
    font - size: 32px;
}
 
p {
    color: green;
    font - size: 16px;
}

CIW Certification Overview#

The CIW HTML CSS Web Development Expert certification assesses your knowledge and skills in HTML and CSS. It covers areas such as HTML5 semantics, CSS3 layout and styling, responsive web design, and cross-browser compatibility. Achieving this certification demonstrates your proficiency in creating professional-quality web pages.

Usage Methods#

Building a Simple Web Page#

To build a simple web page, start by creating an HTML file. Define the basic structure using HTML tags as shown in the previous example. Then, you can add more elements like images, links, and lists.

<!DOCTYPE html>
<html>
<head>
    <title>Simple Web Page</title>
</head>
<body>
    <h1>My Favorite Animals</h1>
    <ul>
        <li><a href="https://en.wikipedia.org/wiki/Dog">Dogs</a></li>
        <li><a href="https://en.wikipedia.org/wiki/Cat">Cats</a></li>
    </ul>
    <img src="dog.jpg" alt="A cute dog">
</body>
</html>

Styling with CSS#

You can style the above web page by either embedding CSS in the <style> tag within the <head> section or by linking an external CSS file.

Embedded CSS

<!DOCTYPE html>
<html>
<head>
    <title>Styled Web Page</title>
    <style>
        h1 {
            color: purple;
        }
        ul {
            list - style - type: square;
        }
        img {
            width: 300px;
        }
    </style>
</head>
<body>
    <h1>My Favorite Animals</h1>
    <ul>
        <li><a href="https://en.wikipedia.org/wiki/Dog">Dogs</a></li>
        <li><a href="https://en.wikipedia.org/wiki/Cat">Cats</a></li>
    </ul>
    <img src="dog.jpg" alt="A cute dog">
</body>
</html>

External CSS Create a file named styles.css with the following content:

h1 {
    color: purple;
}
 
ul {
    list - style - type: square;
}
 
img {
    width: 300px;
}

And then link it to your HTML file:

<!DOCTYPE html>
<html>
<head>
    <title>Styled Web Page</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <h1>My Favorite Animals</h1>
    <ul>
        <li><a href="https://en.wikipedia.org/wiki/Dog">Dogs</a></li>
        <li><a href="https://en.wikipedia.org/wiki/Cat">Cats</a></li>
    </ul>
    <img src="dog.jpg" alt="A cute dog">
</body>
</html>

Common Practices#

Semantic HTML#

Semantic HTML uses tags that convey the meaning of the content. For example, instead of using a <div> for every section, use <header>, <nav>, <main>, <article>, <section>, and <footer> tags. This makes the code more readable, accessible, and SEO-friendly.

<!DOCTYPE html>
<html>
<head>
    <title>Semantic HTML Example</title>
</head>
<body>
    <header>
        <h1>My Blog</h1>
    </header>
    <nav>
        <ul>
            <li><a href="#">Home</a></li>
            <li><a href="#">About</a></li>
        </ul>
    </nav>
    <main>
        <article>
            <h2>My First Post</h2>
            <p>This is the content of my first post.</p>
        </article>
    </main>
    <footer>
        <p>&copy; 2024 My Blog</p>
    </footer>
</body>
</html>

Responsive Design#

Responsive design ensures that a web page looks and functions well on different devices and screen sizes. You can use media queries in CSS to apply different styles based on the device's screen width.

/* For mobile devices */
@media only screen and (max - width: 600px) {
    body {
        font - size: 14px;
    }
    img {
        width: 100%;
    }
}
 
/* For desktop devices */
@media only screen and (min - width: 601px) {
    body {
        font - size: 16px;
    }
    img {
        width: 50%;
    }
}

Best Practices#

Code Organization#

Keep your HTML and CSS code organized. Use indentation and comments to make the code more readable. Separate your CSS into different files based on functionality, such as a layout.css for layout-related styles and a typography.css for font-related styles.

Cross-Browser Compatibility#

Test your web pages in different browsers (e.g., Chrome, Firefox, Safari, Edge) to ensure that they look and function correctly. Some CSS properties may have different implementations in different browsers, so use vendor prefixes when necessary.

/* Example of using vendor prefixes for border - radius */
div {
    -webkit - border - radius: 10px;
    -moz - border - radius: 10px;
    border - radius: 10px;
}
