How to open the source code of the page in Opera

Quite often when training in web-design it is necessary to browse initial codes of someone else's web pages. No additional software for this purpose is required. Any browser suffices, for example, Opera. Instruction 1. Start the Opera browser. 2. Visit the website which HTML-code you wish to view. If necessary, open on it any given pages. 3. If the modern version of the Opera browser is used, press the red button with white letter O located in the upper left corner. There will be a menu. In old versions of the browser and also if in the modern version the classical view is selected, the menu is available in the top part of the screen as it is. 4. Nezavisismo from in what way you opened the menu, select in it item under the name "View". 5. In the appeared submenu select the Source code item. 6. The HTML-code of the page will open in a separate tab. Pay attention that its different fragments are highlighted in the colors for reading simplification. If desired, switch between the page and the source code so many time how many it is necessary to understand what of its fragments are responsible for what displayed elements. 7. Remember that: - it is impossible to send the modified source code to the server; - only the HTML-code of the page is displayed, and it is also impossible to see the maintenance of scripts of "engine" of the website (in particular, in the PHP language); - the current legislation does not allow use of fragments of the code of someone else's pages which are original and created as a result of creative activity (for example, Java scripts), on other websites without the permission of authors of these fragments. 8. If desired, find menu items similar to destination in all other browsers which are available on your computer. Compare the source code of the same page when opening by its other browsers. Perhaps, it will differ a little. It is connected with the fact that some servers, having obtained information on the used browser, slightly change the code of automatically generated page. Earlier it quite often intentionally became to worsen compatibility of the website with different browsers, and today - generally that, on the contrary, to improve it.
