Every major Internet browser allows users to view any web page's HTML (HyperText Markup Language) source code. The following sections contain information on the multiple ways to view the source code in each major browser. To proceed, choose an entry from the list below and follow the instructions.

• Introductory information
• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Microsoft Internet Explorer
• Safari

Introductory information

When viewing the source code of a web page, the information and code processed by the server won't appear. For example, a search engine processes information on a server and then displays the results on a web page. In other words, you can view the code that makes up the results page, but you cannot view the search engine's source code.

This rule applies to all server-side scripts, SSI (Server-Side Include), and programming code. Therefore, you cannot view a script's source code used in search engines, forums, polls, chat, etc. Also, copying the information from the source code may cause errors or direct you back to the page from which you copied the information.

javascript:(function(){var a=window.open('about:blank').document;a.write('Source code of '+location.href);a.close();var b=a.body.appendChild(a.createElement('pre'));b.style.overflow='auto';b.style.whiteSpace='pre-wrap';b.appendChild(a.createTextNode(document.documentElement.innerHTML))})();

8. In Safari, access the bookmarks by tapping the bookmarks icon at the bottom of the screen.

A new Safari browsing tab opens, displaying the source code for the web page.

How to close the source code page or tool

Once done, viewing the source code on a web page, you may want to exit or close it. Closing the source code depends on the method used to open it.

• If you've used the Ctrl+U method (except Edge) or the right-click method, close the new tab that opened at the top of your browser window.
• If you've used the developer method (using F12 or Ctrl+Shift+I), press those same keys again, or click the icon in the upper-right corner of the tools window.
