Yes, simply open the .html file with Chrome or Firefox. These browsers have device mode.
You can change the screen size and see how it looks on mobile or tablet sized screens.
If you save your file .html you can open with firefox or chrome, but i suggest you to use firefox developer edition https://www.mozilla.org/it/firefox/developer/
If you use Firefox you can put in the menu -> development -> flexible display (ctrl+shift+m)
In Chrome (ctrl+maiusc+i + emulation)
In this page you can select the device to view.
Go to https://jsfiddle.net/ to play around with html. It will provide you with warnings if your html is malformed.
Here's an answer to a question that you didn't ask, but is probably what you are looking for:
- Create a new file, call it
index.htmland make sure that the extension is indeed .html. The extension could be something you don't want if you don't have this checkbox checked on windows.
- Right click your file and open it in notepad, then paste this inside it:
<html lang="en"> <head> <title>Simple Page</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> </head> <body> <h1>It works!</h1> <ul> <li>Lists work too</li> <li>Lists work three</li> </ul> </body> </html> - Save the file (
Ctrl + SorFile > Save) - Open your browser (chrome or firefox), and drag the file over your tab bar, or right click the file, choose
open with...and pick your browser.
You should now see the result of the HTML file.
I'm guessing the file is actually named something.html.txt right now.
Take a look at http://www.howtohaven.com/system/show-file-extensions-in-windows-explorer.shtml
Click the Start menu. This is the round icon that is on the bottom left corner of your screen.
Type "folder options" (without the quotes). Click the line "Folder Options" that appears at the top of the Start menu.
A dialog box with the title "Folder Options" will appear. Click the "View" tab at the top of the window.
Click to uncheck the box for "Hide extensions for known file types".
Click the "OK" button at the bottom of the dialog box.
After this you can rename it to drop the .txt
1. Make sure you are using a plain-text editor.
Markup languages like HTML (and, indeed, most code) need to be written in a plain-text file format. That means the file format must not support fonts, bold/italic/underlined text, inserting non-text elements, or any other formatting.
Do not write markup in software like Microsoft Word or Wordpad. Windows ships with a program called "notepad" designed for creating and editing plain-text. You can use that, or consider a plain-text editor specifically geared towards programming and writing markup such as Notepad++ or Sublime Text.
2. Make sure your file is truly an HTML file.
Windows 7 introduced a "feature" which, by default, hides the file extension of any file type it recognizes (i.e., has an associated program to launch it). That means if you name a file index.html, it may have a hidden extension at the end... making the full filename index.html.txt. That's a problem, because the true file extension is now .txt.
I recommend you disable this feature permanently, but you can also do so temporarily (just to check if the file has a hidden extension) if you prefer.
In your start menu, search for "Folder Options" and launch it. In the "View" tab, uncheck the box that says "Hide extensions for known file types" and press "OK" or "Apply".
3. Make sure your document is valid.
Browsers do a pretty good job of "fixing" invalid HTML... most of the time. Nevertheless, if your code has certain mistakes, the browser may default to simply displaying the document as a text file.
Try visiting the W3C Markup Validator to automatically check the validity of your document. If anything is wrong, the validator will point it out and suggest ways of fixing it.
Im now learning javascript and inadvertently went to a page that had all three code windows open - html, css and javascript and at the bottom of the page was the test view.
Im looking for something similar or that page I lost the link to.
Thanks
