How to see the result in the layout and coding, and what tools to use?

The issue has created remembering a video in which the author directly wrote the code, and on a nearby monitor he was the result.
ie he hasn't updated the page, and just wrote code and immediately saw the results.
How is this done?

Write a list of the required js libraries you want to start coding (js, css).
Like a starter template to quickly and competently to impose.
bootstrap,jquery .......

Install the plugin on sublime text 3 Live code. With ctrl+s you will immediately see the changes. Can Live code + auto save combo of the plugins, and each time the code changes automatically save and immediately updates the browser. From poppy eyes don't hurt. There is a display technology retina
Retina is not a display technology, just a marketing designation to the high density of pixels. Technology matrix there IPS. And the matrix there are really very good. Speaking as a owner of Macbook Pro 15 (2017) and Xiaomi Air 13 (2016). Though Xiaomi Air and a very good screen, but the Macbook in this regard — a different League. As a fact, and many more expensive notebooks. - davon.Wuckert commented on March 20th 20 at 11:41
