使用多个html文件创建双语域

I am an extremely beginner level web-designer. Recently I was hired in a company to create a domain from scratch. They requested their domain to be bilingual. I do not know any JavaScript, so I came up with the idea of creating two separate html files in which I translate the content to the required language and then just make a ref link so when the user clicks on the en.icon the English html page pops up.I am an extremely beginner level web-designer.
