From HTML to JavaScript: The Beginner’s Guide to Web Development
Web development is becoming one of the most in-demand fields in the tech industry and it’s no wonder why. Almost every aspect of our lives is now being spent online, from shopping to work to entertainment. This has led to an increased demand for skilled web developers who can create responsive and engaging websites that people want to use. If you’re new to web development, it can be overwhelming to know where to start. That’s why we’ve put together this beginner’s guide to help you learn the basics of web development, from HTML to JavaScript.
HTML
HTML, or Hyper Text Markup Language, is the language used to structure content on a website. HTML is the foundation of all websites and is what gives the webpage its structure. HTML is a markup language, meaning it uses tags to define elements, like headings, paragraphs, links, and images.
To get started with HTML, you’ll need a text editor and a web browser. Notepad or TextEdit will work just fine, and for your browser, we recommend Chrome or Firefox. Start by creating a new file and saving it with the .html extension. In your HTML file, you’ll want to begin with the basic structure of a webpage, which looks like this:
This code sets up the basic structure of a webpage, including the DOCTYPE declaration, the opening and closing HTML tags, the head section, and the body section. The title tag sets the title of the page, which appears in the browser tab. Within the body section, you can add your content using HTML tags. Here’s an example:
Welcome to my website!
This is some sample text for my website.
In this example, we’ve added a header tag with the title of the page, an h1 heading with some welcome text, a paragraph of sample text, and an image. Notice that the image tag includes the source attribute, which tells the browser where to find the image file, as well as the alt attribute, which provides alternative text in case the image can’t be displayed.
CSS
CSS, or Cascading Style Sheets, is used to style and format HTML content. CSS allows you to add colors, fonts, layouts, and other design elements to your website. CSS can be applied to individual HTML elements, groups of elements, or the entire webpage.
To get started with CSS, you’ll want to create a new file with the .css extension. In your HTML file, you’ll need to link to your CSS file using the link tag, like this:
…
Inside your CSS file, you can target specific HTML elements with selectors and apply styles using property-value pairs. Here’s an example:
h1 {
color: red;
font-family: Arial, sans-serif;
font-size: 24px;
}
In this example, we’ve targeted the h1 element with the selector and applied styles using the color, font-family, and font-size properties. You can add as many styles as you like to your stylesheet and they will be applied to your HTML content.
JavaScript
JavaScript is a programming language used to add interactivity and functionality to webpages. JavaScript can be used for everything from form validation to advanced animations and games. JavaScript code can be placed directly in the HTML file or in a separate .js file that’s linked to the HTML file.
Here’s an example of some JavaScript code that adds a button to a webpage and changes the background color when the button is clicked:
In this example, we’ve added a script tag to the head section of the HTML file to define a JavaScript function called changeColor(). This function changes the background color of the webpage to blue. We’ve also added a button to the body section of the HTML file and included an onclick attribute that calls the changeColor() function when the button is clicked.
