Finally, you’ll get a glimpse at various workflow processes and popular tools and resources available to help you create amazing websites.

So let’s get started!

Overview of HTML

HTML stands for HyperText Markup Language, and it is the language which forms the backbone of all websites. HTML files are the files that make up a website, much like how words form a sentence. HTML is made up of elements, such as text, images, videos, and more. Each element must be marked correctly with the correct HTML tags in order for the website to be properly rendered.

HTML is written in a markup language, which means it is composed of HTML elements. An HTML element begins with a start tag, and ends with an end tag, and the content in between the two tags is the content of the HTML element. For example, <p> This is a paragraph </p> is an HTML element, where <p> is the start tag, </p> is the end tag, and “This is a paragraph” is the content of the element.

HTML also includes attributes, which are pieces of information that describe the HTML element. These attributes can include things like colors, sizes, and more. Attributes are placed inside the HTML tag, and are set equal to a value. For example, <img src=”example.jpg”> is an HTML element which has an attribute called src, which is set equal to example.jpg.

Aside from the basic elements, HTML also includes tags for creating lists, tables, links, forms, and more. Learning how to use these tags correctly can help to make your websites look great!

Explaining CSS

CSS stands for Cascading Style Sheets and is a language used in web design. It is responsible for how webpages are styled, including colors, fonts, sizes, positioning, and more.

The main components of CSS are selectors, properties, and values. Selectors refer to the HTML elements that you want to style. Properties describe the features you want to be applied (such as color or font size) and values provide the details of each property (e.g. the color “blue” or a font size of “14px”).

CSS is mainly written in a specific order. The structure of the code usually follows the pattern of “selector {property: value; }”. The “selector” determines which HTML elements will be targeted for styling, while the “property: value” part outlines what feature will be changed and how it should look.

You can also use multiple selectors in one line of CSS. For example, if you wanted to change the font size of all the

tags and the

tag on a page, you could write the following code:

  • p {font-size: 14px;}

  • h1 {font-size: 18px;}

Different Types of CSS

When it comes to writing and using CSS, there are many different types you can use. This includes pre-processors and frameworks. A pre-processor is a type of CSS language that developers can use to write more efficient code. It can be compiled into regular CSS, which browsers can then interpret and use to style web pages. There are several popular pre-processors, such as Less and Sass.

Frameworks are also popular when writing CSS. Frameworks, like Bootstrap or Foundation, provide developers with basic HTML and CSS structures that they can use to quickly develop websites. They come with predefined styles, components, and grids that make them easy to use. Frameworks are great for developing complex designs, but they can be limiting if you want to customize your website.

Using pre-processors and frameworks often makes coding faster, easier, and more efficient. However, they are not the only types of CSS available. Developers can also write their own CSS code from scratch, giving them complete control over how the page looks.

Writing JavaScript is an important part of the website development process. It’s a powerful programming language that adds interactivity to websites and can be used to create some amazing effects. Understanding the syntax and structure of the language is essential if you want to write effective JavaScript code.

The syntax of JavaScript is quite simple, which makes it accessible even to beginners. It follows the same basic structure as other programming languages like Java and C++. The code consists of a series of statements that are executed in order, each statement being separated by a semi-colon. The language supports variables, logical conditions, loops, functions, and other typical features for a programming language.

A JavaScript statement usually starts with a keyword, followed by the code you want to execute, and finally the semi-colon to end the statement. Here is an example of a basic JavaScript statement:

var myString = “Hello World”;

The statement creates a variable called “myString” and assigns the value “Hello World” to it. Variables are used to store data, like strings and numbers, that can then be used in other parts of the code.

In addition to using variables, you can also use logical conditions in your JavaScript code. A logical condition will allow you to perform different actions depending on a given set of conditions. For example, if you wanted to show a different message on your website depending on whether the user was logged in or not, you could use a logical condition like this:

if (userLoggedIn) {

// Show logged in message

} else {

// Show not logged in message

}

These are the basic components of writing JavaScript, but there’s much more to learn. With practice and experience you’ll eventually be able to create complex applications using the language.

JavaScript Libraries & Frameworks

When writing JavaScript, it can help to make use of libraries and frameworks. Libraries are pre-written pieces of code that developers can use to achieve a certain result faster. For example, the jQuery library simplifies how developers can select elements on a web page and manipulate them using JavaScript. Frameworks are more comprehensive than libraries, as they include a collection of tools and components that can be used to structure a complete application.

Popular libraries and frameworks include React, Angular, and Node.js. React is a JavaScript library often used for developing user interfaces, while Angular is an open source framework that helps create full-scale applications with different features. Node.js is another popular framework that can be used to develop server-side applications with JavaScript.

Using these tools can make development easier and faster, but you should also understand the basics of writing pure JavaScript. That way, you won’t be completely reliant on a library or framework to do all of your coding for you.

jQuery

jQuery is a JavaScript library that allows developers to write code more efficiently and effectively. It helps to minimize the amount of code you have to write to achieve a desired outcome, by providing an easy-to-learn API for writing JavaScript. With jQuery, you can quickly add functionality to a website, such as interactive effects, animation, and AJAX requests.

The syntax for jQuery is taken from CSS selectors. For example, you can use the “div” selector to target all div elements on a webpage. You can also use an ID or class attributes when targeting specific elements. From there, you can manipulate them with jQuery methods. For example, you can animate a div element by using the animate() method, or you can use the hide() method to hide a particular element.

jQuery also provides powerful Ajax capabilities, allowing you to make calls to the server without having to refresh the page. This enables you to create dynamic web pages with quick response times. In addition, jQuery also comes equipped with utility functions and cross-browser compatibility, making it a great choice for any web development project.

Sample Workflows & Projects

Developing a web page using HTML, CSS, and JavaScript is a great way to get into web development. It’s not as intimidating as it may first sound and, with the right guidance, you’ll soon be creating a website that looks sleek and professional.

To begin with, you must familiarize yourself with the syntax for each of the three languages. HTML stands for Hypertext Markup Language, and it is used to define the structure of your web page, like headings, paragraphs, lists, and images. CSS is short for Cascading Style Sheets, and it is used to style your HTML elements, like making text bold or italic, adding a background color, or changing font sizes.

JavaScript is used to make your website interactive. This means that your page can respond to user input, like a button click or a scroll. JavaScript can also be used to change the styling of the page, like hiding and showing elements.

Once you know how to write code in the three languages, you’ll need to practice combining them together to create more complex web pages. Start by creating a basic homepage with the three languages, then experiment with styling or adding interactive elements. With enough practice, you’ll be able to build full websites.

Troubleshooting can be one of the most daunting tasks for a website developer, but with the right approach it doesn’t have to be. Debugging your code can help you identify and solve problems quickly and efficiently.

When you’re troubleshooting, the goal should be to isolate the issue to its root cause. That way, you can easily fix the problem and move on. Here are some tips to help you debug your code more effectively:

  • Check your syntax. Make sure everything is written correctly, and all tags and attributes are closed properly.
  • Check for typos. This includes typos in variable names, functions, or other pieces of code.
  • Check the values of variables. Make sure that the values you’re passing into your functions are the ones you intended.
  • Check your logic. Make sure your code is doing what you think it’s supposed to do.
  • Check for dependencies. Are all the necessary libraries and frameworks installed? If so, ensure that they’re loaded properly.
  • Use a debugging tool. If you’re having trouble identifying the issue, a debugging tool can help you track down the problem more easily.

By following these tips and being mindful of common issues, you should be able to troubleshoot your code more easily.

It allows developers to structure content with elements such as headings, paragraphs, images, forms, and videos. Additionally, HTML provides an overall outline for websites so that they are organized and easy to understand.

CSS, or Cascading Style Sheets, is a language used to apply styling to HTML elements. It works by using selectors to identify HTML elements and applies certain properties to them. With CSS, developers can define things like color, font size, position, and background images. There are also other types of CSS, such as pre-processors and frameworks, to make the styling process faster and easier.

JavaScript is a programming language that enables developers to create interactive and dynamic web pages. It runs in all modern web browsers and is ideal for quickly developing web applications. To write JavaScript, you need to understand basic concepts such as variables, functions, arrays, conditionals, and loops. Popular frameworks such as jQuery can also help developers write code faster and more efficiently.

By combining HTML, CSS, and JavaScript, you can create complex workflows and projects. As an example, a simple web page might include a header, footer, multiple sections, and interactive elements such as buttons and form fields. By understanding the fundamentals, you can develop such a website from scratch.

If you ever face any troubleshooting issues, the best approach is to debug the code line-by-line. This way, you can pinpoint any mistakes or sections of code that don’t work as expected.
