HTML and CSS are the fundamental building blocks of the web. HTML (Hypertext Markup Language) is used to structure the content of a website, while CSS (Cascading Style Sheets) is used to control the presentation of that content. Together, these technologies allow developers to create rich and engaging websites that can be accessed by anyone with an internet connection.

In this beginner’s guide to HTML and CSS, we’ll provide an overview of what these technologies are, how they work together, and some basic tips for getting started with web development.

What is HTML?

HTML is a markup language that is used to structure the content of a website. It consists of a series of elements that are placed within tags, which are used to indicate the type of content that each element contains. For example, a paragraph of text might be marked up like this:

<p>This is a paragraph of text.</p>

In this example, the <p> and </p> tags indicate that the content between them is a paragraph. The <p> tag is known as the opening tag, and the </p> tag is known as the closing tag. The content between the opening and closing tags is known as the element’s content.

HTML elements can be nested within each other to create more complex structures. For example, a list of items might be marked up like this:

<ul>
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
</ul>

In this example, the <ul> and </ul> tags indicate that the content between them is an unordered list, while the <li> and </li> tags indicate that each item in the list is a list item.

HTML also includes a variety of attributes that can be used to provide additional information about an element. For example, the href attribute can be used to specify a link’s destination, like this:

<a href="http://example.com">This is a link</a>

In this example, the href attribute is used to specify that the link’s destination is http://example.com.

What is CSS?

CSS (Cascading Style Sheets) is a language that is used to control the presentation of a website’s content. It allows developers to specify the font, color, size, and other visual aspects of a website’s elements. For example, a developer might use CSS to specify that all paragraphs on a page should be rendered in red Arial font, like this:

p {
  color: red;
  font-family: Arial;
}

In this example, the p selector is used to target all paragraph elements on the page, and the color and font-family properties are used to specify the font color and font family, respectively.

CSS also includes a variety of other features that can be used to create more complex and engaging designs. For example, developers can use CSS to control the position of elements on a page, create animations and transitions, and even create layouts that automatically adapt to the size of the user’s screen.

How do HTML and CSS work together?

HTML and CSS work together to create the structure and presentation of a website’s content. The HTML provides the structure and content of the page, while the CSS provides the styling and presentation of that content.
