Lesson One: Web Browsers
Welcome to the Web Design course! In this first chapter, you are going to learn about the tools and languages used to create and display web pages.
You are most likely viewing this lesson through a web browser. A web browser is a software program that can display web pages on your computer. These programs work like foreign language translators, changing mysterious web page code into a form that the reader can easily view and understand. Web browsers are the preferred way to view most of the information that is available on the World Wide Web (WWW).
Common Browsers
Microsoft Edge, Mozilla Firefox, Google Chrome and Apple Safari are the names of common browsers used on desktop and laptop computers today. Mobile phones and tablets also contain built-in web browsers that know how to display pages on a small screen.
For a long time, the Microsoft "Internet Explorer" (or "IE") browser was widely used. It came pre-installed on Windows operating systems, so Windows users did not have to take any extra steps to install or configure this program. With the introduction of Windows 10, Microsoft released a new web browser called "Edge". Internet Explorer is still present, but Edge is the default browser. However, many users will choose to install and use other web browsers on their Windows computers.
"Firefox" is a free alternative browser that works on both Windows and Mac computers. Firefox started as a response to complaints from unhappy IE users and is maintained by a large group of volunteer programmers. These volunteers invented many useful features that other browsers soon adopted.
Firefox is an example of open source software, which means the source code is free for anyone to download and examine. If you want to see how a feature works, suggest new features, or contribute fixes on your own, then using open source software is a good choice. Most other web browsers are closed source, so only the companies that own the browsers will work with the source code. In that case, paid professionals will maintain and expand the browser features.
If you use a Mac OS X computer, chances are you are using the "Safari" web browser. Apple includes the Safari software with every Mac OS computer, iPhone and iPad. Safari can be installed on Windows computers too, but it is mostly used on Mac computers.
The Google "Chrome" browser was first released in 2008 and has rapidly become very popular. In fact, it is now the most widely used browser and is available on both Windows and Mac computers. Because Chrome is made by Google, Inc., it works very well with many other Google applications like Google Search and Gmail.
You can use any of these major browsers as you develop web pages for this course. You may even want to install more than one browser, and test your web pages to make sure they look great in different programs.
Comparing Browsers
What browser program do you prefer? Most web pages will look very similar on different browsers, but there may be small differences. Each browser has different strengths and features. The browser you choose may depend on the websites you visit or how you use the Internet.
Each browser program has the same basic components, even if they are displayed slightly differently. Below we have shown example web pages from Chrome, Firefox, Edge and Safari. Your own web browser may look different because these programs can be configured to hide or show different elements, or you might be running a newer version with an updated style.
The numbered areas show some features common to most browsers:
The first area displays the title of the web page. If you have more than one website open, you may see multiple "tabs", each with their own title.
The second area contains the address (also called the Uniform Resource Locater or URL) of the page within the World Wide Web. If you know the address of your website, you can type it directly into the address bar in order to go directly to that page.
The large central area shows the web page content. If the web page has been designed properly, this content area should look the same in different web browsers. However, individual web browsers may display things slightly differently.

Why is it important to test your web page on different versions of the same browser?
1. Some of the different browsers on the market today include Microsoft Edge, Mozilla Firefox, Google Chrome, Apple Safari, and Internet Explorer.
2. There are different browsers because they have different strengths, features, and compatibility with certain websites and applications. People have different preferences and needs when it comes to web browsing, so having a variety of options allows users to choose the browser that best suits their requirements.
3. - The title area displays the title of the web page and often shows multiple tabs if there are multiple websites open.
- The address bar, also known as the URL bar, displays the address or URL of the webpage. Users can directly type the URL of a website in the address bar to navigate to that page.
- The content area is the main area of the browser window where the web page content is displayed. This area should ideally look the same in different browsers, but there can be slight variations.
4. Web browser software can usually be found on students' computers by checking the default applications or programs installed. On Windows computers, Microsoft Edge or Internet Explorer is usually pre-installed. On Mac computers, Safari is typically included. Students can also download and install other browsers like Firefox or Chrome directly from their respective websites.
5. It is important to test your web page on different browsers to ensure compatibility and consistent display across different platforms. Different browsers may interpret and display HTML and CSS code differently, leading to variations in how your web page appears. Testing on different browsers helps identify any compatibility issues and allows you to make necessary adjustments for optimal user experience.
6. The purpose of the World Wide Web Consortium (W3C) is to develop and maintain web standards. The W3C creates guidelines and recommendations for web technologies to ensure interoperability and compatibility across different browsers and devices. Adhering to W3C standards helps ensure that web pages function correctly and are accessible to all users.
7. It is important to test your web page on different versions of the same browser because different versions may have varying levels of support for web technologies and different rendering engines. Older versions of browsers may not support newer HTML, CSS, or JavaScript features, resulting in compatibility issues. Testing on different versions allows you to identify and address any potential issues for users who may be using different browser versions.
Some of the different browsers on the market today include Microsoft Edge, Mozilla Firefox, Google Chrome, Apple Safari, and Internet Explorer (although it is less commonly used now).
There are different browsers because they are developed by different companies or organizations, each with their own features, functionality, and design choices. Competition among browsers helps drive innovation and improvements in web browsing technology.
The title area of a web browser displays the title of the web page. This allows users to quickly identify the currently opened page, especially if there are multiple tabs open. The address bar, also known as the URL bar, displays the website address or URL of the current page and allows users to directly enter a specific URL. The content area is the central part of the browser window where the web page content is displayed. It should appear the same in different browsers if the web page has been designed properly, but minor differences may occur due to how each browser interprets and renders the page.
To find web browser software on students' computers, they can check their operating system's application menu or search for browser names like "Google Chrome" or "Mozilla Firefox" using the search function. They can also go to the respective browser's official website and download the latest version from there.
It is important to test a web page on different browsers because browsers may interpret and render web pages differently. Layouts, styles, and functionality can vary among browsers, so it is essential to ensure that the web page looks and functions correctly across different browser platforms. This helps provide a consistent and optimal user experience for all visitors.
The purpose of the World Wide Web Consortium (W3C) is to develop and maintain web standards and protocols. The W3C ensures that web technologies are interoperable, meaning that they work consistently across different platforms and devices. It sets guidelines and specifications for HTML, CSS, and other web technologies. Adhering to W3C standards helps ensure cross-browser compatibility and creates more accessible and well-designed web content.
Testing a web page on different versions of the same browser is important because browser updates can introduce changes to rendering engines, CSS support, and JavaScript functionality. Older versions of a browser may not support newer web technologies or may have different interpretations of the same web standards. Testing on different versions helps identify and address any compatibility issues and ensures a consistent experience for users using different browser versions.
How does Python know you've reached the end of a code statement?
A. You placed a hash-tag (#) at the end of each line
B. You hit the "Enter" key to move to the next line
C. You place an equals sign (=) at the end of each line
D. You place a semicolon (;) at the end of each line
1. Some of the different browsers on the market today include Microsoft Edge, Mozilla Firefox, Google Chrome, Apple Safari, and Internet Explorer.
2. There are different browsers because they are developed by different companies or organizations, each with their own unique features, user interfaces, and performance. Additionally, the competition among different browsers promotes innovation and choice for users.
3. The title area of a browser displays the title of the currently open web page. The address bar, also known as the URL bar, shows the address or location of the web page you are currently viewing. The content area is the main part of the browser window where the actual web page content is displayed. While the general layout and functionality of these components are similar across browsers, there might be slight differences in their appearance and placement.
4. Web browser software can be found on students' computers through different methods depending on the operating system. For Windows computers, the default browser may be Microsoft Edge, while for Mac computers, it may be Safari. However, students can also download and install other browsers like Mozilla Firefox or Google Chrome directly from their respective websites.
5. It is important to test your web page on different browsers to ensure that it looks and functions correctly across different platforms. Different browsers may have variations in how they interpret and render web page code, which can lead to differences in appearance or functionality. By testing on different browsers, you can identify and fix any issues to provide a consistent user experience.
6. The World Wide Web Consortium (W3C) is an international community that develops standards and guidelines for the web. Its purpose is to ensure that the web is accessible, interoperable, and well-designed for all users. W3C develops protocols and technical specifications that help standardize web technologies, making it easier for developers to create compatible websites and for users to access content on different browsers and devices.
7. It is important to test your web page on different versions of the same browser because updates to browsers can introduce new features, improve security, and fix bugs. However, these updates can also lead to changes in how the browser interprets and renders web page code, potentially affecting the appearance and functionality of your web page. By testing on different versions of the same browser, you can ensure that your web page maintains compatibility and performs consistently across different browser versions.
