Edge Code allows speed up development cycle by connecting directly to your browser for automatic real-time updates to the HTML content running inside the browser. It enables you to focus on writing your code rather than worrying about all the required steps in switching between your editor and browser and step through development and debugging iterations.
Now let’s take a look at some of the coolest features of Edge Code CC.
Live Preview allows you to edit your code side by side with a Chrome browser that displays the HTML page you are editing in Edge Code CC. To activate the feature, click on the Live Preview icon at the top right of the app window or go to File > Live Preview.
As you change the CSS properties, the changes are pushed to Chrome without having to actually save the files and reload the page in Chrome. You also get visual clues on what you are editing.
If you change your HTML code, then the Chrome browser will automatically reload the page after saving HTML file.
