Study Notes
Web Development with HTML
HTML stands for Hypertext Markup Language, which is used to create web pages by structuring text, images, links, forms, etc., into meaningful and organized documents. Here's how you can start working with HTML for your web project:
Setting Up Your Environment
To work with HTML and other parts of web development like CSS and JavaScript, you would typically need:
-
A code editor or IDE (Integrated Development Environment) to write your HTML files. Examples include Visual Studio Code or Atom
-
An HTTP server (like Apache or Nginx) to serve your static HTML files over the internet so others can see them via their browser.
Basic Structure of an HTML Document
An HTML document consists of two main elements—the <html> element and the <head> element. Within the body section (</body></html>) lie the visible page contents, such as headings, paragraphs, lists, tables, and other formatting information.
<!-- Example structure -->
<!DOCTYPE html>
<html lang="en">
<head>
<!-- meta tags and scripts here -->
</head>
<body>
<!-- visible page contents go here -->
</body>
</html>
Creating Headers and Paragraphs
The most basic building block of any webpage is the header and paragraph. These are created using the respective HTML tags: heading tags (e.g., <h1>, <h2>, …) and paragraph tags (`
"). For example:
<p>This is my first paragraph.</p>
<h2>This is a heading level 2</h2>
Adding Images and Links
Adding visual media like images requires the <img /> tag followed by its source URL enclosed within quotations. Similarly, adding clickable links involves the <a href="URL_here"/> format.
<img src="https://example.com/image.jpg"></img>
<a href="https://www.google.com">Click me!</a>
Formatting Text and Styling Pages with Cascading Style Sheets (CSS)
While HTML provides some basic styling options through tags (such as bold, italic, font size), more complex layouts require external stylesheets written in CSS (Cascading Style Sheets).
For instance, to change the color of your header text, you might write in your separate CSS file something like this:
header {
background-color: #f9fafd;
}
Then link this .css file to your HTML file by using the link tag inside your <head>. For example:
<link rel="stylesheet" type="text/css" href="/styles.css">
These examples only scratch the surface of what's possible with HTML. As you delve deeper into the world of frontend programming, you'll encounter additional concepts like forms, interactive components, animations, and responsive design. However, mastering HTML alone will equip you to build incredibly useful websites from the ground up.
