Adventure Works uses a SharePoint publishing site for an external website at www.adventureworks.com. The
user interface is implemented by using HTML5, CSS 3, and JavaScript.
You need to ensure that the site designers have an efficient way to create and modify the JavaScript files.
What should you do?

A.
Open the site in SharePoint Designer. From All Files, double-click the _cts folder and then select the
MasterPages folder. Create a folder. Modify the JavaScript files by using Microsoft Notepad.

B.
Copy all the JavaScript files to a document library and modify them directly by using Microsoft Notepad.

C.
Open the site in SharePoint Designer. From Master Pages select the JavaScript files to modify them.

D.
Set up a mapped network drive in Design Manager. Open the mapped drive and create a folder. Modify the
JavaScript files by using Microsoft Notepad.

Explanation:
Master Page – Use SharePoint Designer to add code to a master page when you want to code to be available
on every page in a site. You can add the JavaScript inside of <SCRIPT> tags or link to a file that contains the
JavaScript. Typically add your CSS just before the </HEAD> section and your JavaScript just before the </BODY> tag.
