It can be highly effective to understand a webpage's source code. It allows you to spy on the designing of a webpage. Examining the original code can teach you a lot. This may include the way a portal looks, how it interacts with the server, and how it reacts to user input. We shall examine the basics. of webpage source code in this blog post.
The source code of a webpage is important for several reasons. First, it helps web developers understand how a webpage functions. They can see the structure and design elements of the page. Second, it allows developers to debug issues on a webpage. By looking at the source code, they can identify and fix problems. Third, learning to read source code can help beginners improve their coding skills.
Basic Terminology
You must be cognizant of a few significant terms in order to effectively read webpage source code. Hypertext Markup Language is officially referred to as HTML. It is the common language used for writing web pages. Cascading Style Sheets is what CSS stands for. It outlines the proper appearance of HTML elements on a webpage. JavaScript is a language used for programming. You can use it to add gadgets to your webpage.
Another important term is "tag." Tags are the building blocks of HTML. They tell the browser how to display the content. For example,
is a tag for a paragraph. Attributes provide additional information about HTML elements. For instance, the class attribute specifies a class for an HTML element.
It can be useful to view a webpage's source code. It aids developers in discovering the structure of a webpage. You can view the source code using a variety of tools. These tools usually are easy to use. Here are a few widely used ways to see the source code.
Built-in Browser Tools
Tools for viewing source code merge into an overwhelming number of the present-day browsers. Developers will find these tools very valuable. Voicing are a few of the most utilized browser tools:
Google Chrome: First right-click or press Ctrl+U; next, locate "View page source."
Mozilla Firefox: both right-click or press Ctrl+U, afterward click "View Page Source."
Microsoft Edge: Work with a computer quickly: Ctrl+U or right-click and select "View page source."
Safari: Move "Develop" and preference "Show Page Source."
These tools let you see the HTML, CSS, and JavaScript of a webpage. They also offer features like inspecting elements and debugging code.
Another manner to read the source code depends on online code viewers. These web-based tools offer no need for installation. Here are some popular online code viewers:
View Page Source: Enter the URL of the webpage to view its source code.
Code Beautify: A tool that formats and displays the HTML, CSS, and JavaScript.
HTML Viewer: A simple tool to view and edit HTML code online.
These online tools are easy to use. They are great for quick checks and learning purposes.
Accessing Developer Tools is simple.Developer tools have been constructed into a large majority for modern browsers.
For Google Chrome, there is an option to either right-click and choose "Inspect" or press Ctrl + Shift + I.
For Mozilla Firefoxprimarily hover over an element and choose "Inspect Element" or press Ctrl + Shift + I.
For Microsoft Edge, this is done by a choice of making a right-click "Inspect" or pressing Ctrl + Shift + I.
A group composed of several tabs, such as Elements, Console, and Network, should appear once it was originally opened.
The Elements tab is where you can see the source code.
The corresponding element on the webpage may constitute emphasis by fluctuating over the HTML code. Finding the precise code you're looking for is made simpler as a result.
Any element in the Elements tab can be right-clicked. The element will be easily accessible for correction, copying and pasting, or leaving.

Action |
Shortcut |
|
Edit HTML |
Right-click > Edit as HTML |
|
Copy HTML |
Right-click > Copy > Copy Outer HTML |
|
Delete Element |
Right-click > Delete Element |
These options are useful for testing changes on the fly. You can see how changes affect the webpage in real time without permanent alterations.
Remember, changes made in Developer Tools are not saved. Refresh the page to revert back to the original state.
For web development, it is paramount to become familiar with the structure of HTML. Any webpage's primer is HTML (HyperText Markup Language). It defines the content and structure. Knowing HTML helps in modifying and troubleshooting web pages.
HTML uses tags to create elements. Tags are enclosed in angle brackets. For example,
for a paragraph. Each tag has an opening and a closing tag. The closing tag has a slash, like .
Attributes provide additional information about an element. They are written inside the opening tag. For example, Link. The href attribute specifies the URL.
Several HTML elements are frequently used. These include headings, paragraphs, links, and images. Headings range from
to
.
is the most important, and
is the least.
Paragraphs use the
tag. Links are created with the tag. Images use the tag, which has attributes like src and alt. The src attribute specifies the image source. The alt attribute provides alternative text.
Lists are also common. Ordered lists use the
tag, while unordered lists use the
tag. List items are wrapped in
tags.
For web developers, accepting a webpage's CSS styles is essential. Cascading Style Sheets, or CSS, control how HTML elements show up on a page. You may observe how various literary procedures impact the way a site seems and feels by investigating CSS styles.
There are two main ways to apply CSS: inline and external.
Inline CSS: This style is applied directly within an HTML tag. It is useful for quick, one-off style changes.
External CSS: This style is linked through a separate CSS file. It is ideal for consistent styling across multiple pages.
Here is an example:
|
Inline CSS |
External CSS |

Apply the developer tools in your browser and look at the elements to comprehend the styles used on a webpage.
Maybe you can select "Inspect" or "Inspect Element" by using a right-click on the webpage.
To examine the HTML structure, figure out the "Elements" tab.
Click on an element to view its CSS styles in the "Styles" pane.
You can also see which styles are overridden or inherited. This helps in debugging and refining your webpage design.
Understanding the JavaScript in a webpage's source code can be very helpful. It allows you to see how the webpage functions. JavaScript controls many elements on the page. By examining the source code, you can learn more about these elements and how they work together.
Embedded scripts are JavaScript codes written directly within the HTML file. They are placed between the tags. These scripts run as the HTML page loads. You can find these scripts usually within the or sections. Embedded scripts are easy to spot in the source code. They are useful for small, specific tasks.
External JavaScript files are stored in separate .js files. These files are linked to the HTML document using the tag with a src attribute. This approach keeps the HTML file cleaner. It also makes the JavaScript code reusable across multiple pages. External files improve the loading speed of the webpage. They allow browsers to cache the script files.
Extracting assets and resources from a webpage is crucial. It helps in understanding the webpage's structure. This process involves fetching images, media, fonts, and icons. Let's dive into each category to see how you can extract them.
Images and media files are essential parts of a webpage. They enhance the user experience. To extract these assets, you need to identify the image tags and media elements. Here is a simple example of how to extract image URLs:
Use browser developer tools to inspect the elements. Right-click on the image and select "Inspect." You will see the image source URL in the HTML code. Copy the URL to download the image.
Icons and fonts are significant aspects of a webpage's design. They sharpen the content's access and a pleasing appearance.To extract fonts, look for the font-face declarations in the CSS files:
@font-face {
font-family: 'MyFont';
src: url('myfont.woff2') format('woff2'),
url('myfont.woff') format('woff');
}
For icons, you may find them within icon libraries like FontAwesome. Inspect the HTML to find the class names used for icons:
Use the class name to locate the icon in the library and download it.
A look at a webpage's source code can provide helpful ideas. However, it's critical to follow the ethical issues at work.This ensures respect for intellectual property and promotes fair use in development. Below are key points to keep in mind.
