Hi Ravinder,
It's good to learn basic HTML, Plain Vanilla Javascript and CSS before moving on to JS libs and frameworks like Vue.js.
However, you should try to master the basics soon and move to developing in node.js and Vue.js sooner than later.
Also, if you are going to keep working with the very bare bones, at least consider working with Bootstrap classes.
Cheers and Keep Learning!
