We have released a new book “Content Marketing in in social networks: How to get into your subscribers’ heads and make them fall in love with your brand.”
The source code of the site is a set of HTML markup, CSS styles and JavaScript scripts that the browser receives from the web server.

It can be compared to a set of commands given to soldiers by a commander. Imagine that the audience does not see or hear the boss. From their point of view, the military carries out actions independently. In our case, the commander is the browser, the commands are source, and marching soldiers are the end result.
The site is stored on a web server, which sends the page upon user request. A request is typing a URL in the address bar, clicking a link, or clicking a submit button on a form. It doesn’t matter what language the web pages are written in or whether they include a software component. The end result of any server-side algorithm is a set of html tags and text.
The page source code is a set of data that includes:
- html markup;
- style sheet or file link;
- programs written in JavaScript or links to files with code.
These three sections are processed by the browser. For the server, this is simply the text that needs to be sent in response to the request.
Why we might need to study the source code
Everything we see, we can analyze and apply to solve certain problems that arise while working with the site, especially when optimizing it. By looking at the source code, we can:
- See the meta tags of your or someone else’s site to analyze them.
- See the presence or absence of certain elements on the site: counters, identification codes in various systems, certain scripts and other things.
- Find out the parameters of the elements: sizes, colors, fonts.
- Find the path to photos and other elements located on the page.
- Explore links from the page.
- Find problems with the code that interfere with the process of website optimization: those not addressed in separate files styles, scripts, invalid code.
These are the basic features, but in fact, by being able to read the code, you can learn a lot more about the page.
How to view the source code of a site
It will not be possible to do this completely in the form in which it is posted on the server from the browser. But you can see all the markup by right-clicking on the page. Here and below using an example Google Chrome.
Select the “View page code” option and get the full listing in a separate tab.
It's just text that you have to analyze to understand. But you can get interactive code using the developer tools.
How to find the source code of a website page
Click on the menu icon in the browser. Most often it is on the right and looks like three dots or stripes.
In the additional tools section, select “Developer Tools”.
A window will open showing the active state of the code. This means that when you click on the markup, the element style will appear next to it, and the selected blocks will be highlighted on the page.
In the “Source” tab you can view the contents of some files: scripts, fonts, images.
In the “Security” tab, you can check the site’s certificate.
The “Audits” tab will help you check the resource posted on the hosting.
If the location of the panel on the right is inconvenient, you can click the three dots and change it by selecting the desired item.
How to view meta tags
Every HTML document includes structure tags. Here are some of them:
- Html – the entire document.
- Head – section of service headers.
- Title – page title (displayed on the tab).
- Body – the body of the document.
- H1-H6 – page text headings.
- Article – article.
- Section - section.
- Menu – menu.
- Div – block.
- Span – string.
- P – paragraph.
- Table – table.
Elements are designed to logically delimit sections on a page; if necessary, they are designed using styles. They contain text that is somehow visible on the page. But the Head tag contains service information. Meta tags are used to indicate it. Everything that is written in them is intended for the server and search engines.
Their contents cannot be found out in any other way.
Let's pay attention to the Link tag. With its help, links to external included files are specified. If desired, you can see the contents and save to disk. To do this, move the pointer to the address and press RMB. Select "Open in new Tab".
Will open in a new tab specified file, which you can view or save.
How to view the source code of a page to debug a script
In this case, it is most convenient to open the page on the local machine. If you only need to correct markup, styles and scripts, then this can be done directly from the folder. The HTML code is viewed in the same way. Here are the mistakes JavaScript code can be seen in the “Console” tab. This shows the description of the error and the line number where it occurred.
The syntax can be seen directly in the code. This is what the “Source” tab is for.
How to view the code of a specific element
For large pages with many elements, it is difficult to find the necessary code in all the markup. In this case, you should use special team context menu. Move the mouse over the fragment and press RMB. Select the “View Code” command.
The same window will open, but with the focus on the selected object.
Summary
We told you what the page source code is. It is enough to master basic knowledge of HTML and CSS, and using convenient developer tools, you will be able to debug your own HTML documents.
Viewing resource code on the Internet will allow you to learn not only from own experience, but also use real working examples. And for SEO specialists, meta tags will be useful, the information in which can tell a lot about the site.
For a long time, the “show page source” option was useless and uninteresting for me. So far, learning HTML on Codecademy and designing my own websites has not grown into my new hobby. This is where the question arose: where to find real cases and borrow interesting solutions for your “piggy bank”? The answer was unexpectedly simple, like all ingenious things: look at the source code of the page in Google Chrome! I share with you my modest finds.
What is the page source code
If you, like me, are just taking your first steps in HTML programming, it would be a good idea to find out what the source code of a page is.
Source code, also known as HTML page code, is text in Hyper Text Markup Language (HTML). It includes the actual page content (text, tables) and tags. The latter act as instructions for the browser: how to display content, what type of formatting to use, where to insert a hyperlink or media file. Well, for us, novice programmers, the source code is the best training ground: we find an interesting site and spy on it, save it, and use successful fragments. How?
How to view the source code in the Google Chrome browser page
Find the page you like. For example, I was interested in the design of the site menu. There are three ways to open the source code in the Google Chrome browser:
- Click on the icon menu in the upper right corner of the browser and select “More tools”. Among others, there is an option “View source code”. Frankly, I rarely use it this method: a lot of unnecessary movements. It can be made even simpler.
- Press the key combination Ctrl+U– a new window with the source code opens;
- For fans of the context menu: click right click mouse over the page and select the “View page code” option.
We coped with the task of viewing the HTML code of the page in the browser. Let's move on to the most interesting stage.
How to edit and save source code
To learn how to create websites, it is not enough to read someone else's HTML code. You need to play with it, experiment, make changes and check the result. You can even start by compiling a few successful samples. How to edit and save source code?
Option 1. “Manually”
After we have opened the source code of the page, call the context menu and select the “Save as” option and save the file to HDD. We edit the file in Notepad or Notepad, save the changes and open it through the browser. The results of our changes (successful and not so successful) will be reflected in the browser window.
Option 2. For the pros
When you "play" with source code every day, the process of "save - open - change - save - check" becomes tiring. For myself, I found a solution in the form of installing a plugin for Google Chrome - Firebug Lite. It allows you to edit and save source code without leaving the browser window.

The invited user receives a discount of 4,000 rubles for the first 5 months of using the service.If you open any web page, it will contain typical elements that do not change depending on the type and focus of the site. Example 4.1 shows the code for a simple document containing basic tags.
Example 4.1. Web page source code

Copy the contents this example and save it in the c:\www\ folder as example41.html. After that, launch the browser and open the file through the menu item File > Open File (Ctrl+O). In the document selection dialog, select the file example41.html. The web page shown in Fig. 1 will open in the browser. 4.1.

Elementis intended to indicate the type of the current document - DTD (document type definition, description of the document type). This is necessary so that the browser understands how to interpret the current web page, because HTML exists in several versions, in addition, there is XHTML (EXtensible HyperText Markup Language), which is similar to HTML, but differs from it in syntax. So that the browser “does not get confused” and understands according to which standard to display the web page, it is necessary to set in the first line of code .
There are several types, they differ depending on the version of HTML they are targeting. In table 4.1. The main types of documents with their descriptions are given.
DOCTYPE | Description |
---|---|
HTML 4.01 | |
Strict HTML syntax. | |
Transitional HTML syntax. | |
An HTML document uses frames. | |
HTML 5 | |
This version of HTML has only one doctype. | |
XHTML 1.0 | |
Strict XHTML syntax. | |
Transitional XHTML syntax. | |
The document is written in XHTML and contains frames. | |
XHTML 1.1 | |
The developers of XHTML 1.1 expect it to gradually replace HTML. As you can see, this definition has no division into types, since the syntax is the same and obeys clear rules. |
The difference between a strict and transitional document description is a different approach to writing document code. Strict HTML requires strict adherence to the HTML specification and is unforgiving of errors. Transitional HTML is more relaxed about some code flaws, so this type is preferable to use in certain cases.
For example, in strict HTML and XHTML the presence of the tag is required
In the future we will mainly use strict, unless otherwise specified. This will allow us to avoid common mistakes and teach us to write syntactically correct code.
You can often find HTML code without using any, the web page will still be shown in this case. However, it may happen that the same document appears differently in the browser when you useand without it. In addition, browsers can display such documents in their own way, as a result the page “crumbles”, i.e. will be displayed completely differently from what the developer requires. To avoid such situations, always addto the beginning of the document.
Tag defines the beginning of the HTML file, the header is stored inside it (
) and document body (Document title, also called a block
, can contain text and tags, but the content of this section is not directly shown on the page, except in the container
Tag is universal and adds a whole class of capabilities, in particular, with the help of meta tags, as this tag is generally called, you can change the page encoding, add keywords, document description and much more. So that the browser understands that it is dealing with UTF-8 encoding (Unicode transformation format), and this line is added.

By default, the first level heading is displayed in the largest bold font, and subsequent level headings are smaller in size. Tags ...refer to block elements, they always start with new line, and after them other elements are displayed on the next line. Additionally, white space is added before and after the title.

Some text can be hidden from being shown in the browser by making it a comment. Although this text will not be seen by the user, it will still be transmitted in the document, so if you look at the source code, you can discover hidden notes.

The program code may vary in terms of privacy - many developers do not make it publicly available and the terms of the license agreement impose restrictions on users regarding its use and viewing. There are also programs with open source, which can be viewed, edited, and so on.
You will need
- - a program for opening source code.
Instructions
Make sure the source code is software, which you want to view is intended for open access. To do this, go to the official website of the software developer and view the license type. If the source code of the program is closed, you cannot view it. This is inconvenient, but with such a system it is quite rare to find copies of a program containing Trojans and other malware. This is the main disadvantage of free software.
If you have free software, find “Source Code” in the program menu, if such an item is provided by the developer, which is extremely rare. To view it in other cases, use an assembler or other third-party software.
Often, to open the source, you need to know what programming language the creators of the program used during development, which is often very difficult to determine. Here you can install the set on your computer various programs to open source code written in different languages.
When using free software, if you have the option, review the source code before the installation process, especially if the program was downloaded from an unofficial source. This will help protect your computer from malware that is installed along with the main one.
Also don't resort to various methods making changes to the closed source code of a program, often in such cases there is certain liability for violating the rules license agreement between the user and the developer. Moreover, do not post edited such programs on the Internet.
