Fundamental Concepts

HTML Basics

HTML is a markup language used to create the structure of a web page. It consists of a series of elements, which are represented by tags. Tags are enclosed in angle brackets (<>). For example, the <html> tag is the root element of an HTML document, and it encloses all other elements. The <head> tag contains metadata about the page, such as the title and links to external resources, while the <body> tag contains the visible content of the page.

<!DOCTYPE html>
<html>
<head>
    <title>My Web Page</title>
</head>
<body>
    <h1>Welcome to my web page</h1>
    <p>This is a paragraph of text.</p>
</body>
</html>

CSS Basics

CSS is used to style HTML elements. It works by selecting HTML elements and applying styles to them. A CSS rule consists of a selector and a declaration block. The selector identifies the HTML elements to which the styles will be applied, and the declaration block contains one or more declarations, each of which consists of a property and a value.

/* Select all h1 elements and set their color to blue */
h1 {
    color: blue;
}

Usage Methods

HTML Tags and Elements

In 2018, HTML5 was widely adopted. It introduced many new tags and elements that made web development more efficient and semantic. For example, the <article> tag is used to represent a self - contained piece of content, such as a blog post or a news article. The <section> tag is used to group related content within a page.

<article>
    <h2>Article Title</h2>
    <p>This is the content of the article.</p>
</article>

CSS Selectors and Properties

CSS selectors allow you to target specific HTML elements. There are different types of selectors, such as element selectors, class selectors, and ID selectors. Element selectors target all elements of a particular type, class selectors target elements with a specific class attribute, and ID selectors target a single element with a specific ID attribute.

/* Element selector */
p {
    font - size: 16px;
}

/* Class selector */
.my - class {
    background - color: yellow;
}

/* ID selector */
#my - id {
    border: 1px solid black;
}

Common Practices

Responsive Web Design

In 2018, responsive web design became a standard practice. It ensures that a web page looks and functions well on different devices, such as desktops, tablets, and smartphones. Media queries in CSS are used to apply different styles based on the device’s screen size.

/* Media query for screens smaller than 600px */
@media screen and (max - width: 600px) {
    body {
        font - size: 14px;
    }
}

Semantic HTML

Semantic HTML involves using HTML tags that convey the meaning of the content. This makes the code more readable for developers and also helps search engines understand the structure of the page. For example, using <header>, <nav>, <main>, and <footer> tags to define the different sections of a page.

<header>
    <h1>Website Title</h1>
</header>
<nav>
    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">About</a></li>
    </ul>
</nav>
<main>
    <p>Main content goes here.</p>
</main>
<footer>
    <p>&copy; 2018 My Website</p>
</footer>

Best Practices

Code Organization

Keeping your code organized is essential for maintainability. In HTML, you can use indentation and comments to make the code more readable. In CSS, you can group related styles together and use a modular approach. For example, you can create separate CSS files for different sections of a page.

Performance Optimization

In 2018, performance optimization was a key concern. Minifying HTML and CSS files can reduce their file size, which leads to faster loading times. You can also optimize images and use browser caching to improve performance.

Conclusion

In 2018, CSS and HTML continued to evolve, with the adoption of new features and best practices. Understanding the fundamental concepts, usage methods, common practices, and best practices of CSS and HTML is crucial for web developers. By following these guidelines, developers can create web pages that are not only visually appealing but also performant and accessible across different devices.
