Create your own Scaffolded Item. When you Add -> New Item…, there is also option New Scaffolded Item…. You can add your new scaffolded item as one of the options. You can copy and modify existing scaffolded items found at C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\Microsoft\Web\Mvc\Scaffolding\Templates(for Visual Studio 2017). Copy folder you want to modify and paste it under CodeTemplates folder under your project root. Make sure names of folders/files are intact so Visual Studio can pick them up.
Install Web Essentials extensions which provides the ultimate web development experience, such as the Browser Reload on Save, CSS Tools, HTML Tools, and ZenCoding.

Use LESS which extends CSS with features such as variables, mixins, and nested rules.
