Which is better for developing web interfaces?

Question

JavaScript

Good afternoon!
I am asking for the following advice: what is better to use (libraries, frameworks) to create beautiful and good web interfaces. So for a long time the desires for the creation of "beautiful" do not have time to "chase" the technological process. As a result, a lot of time is spent, and the result of the work is often not what one would expect. Thanks in advance for the suggestions.

Answer 2

It is better to use ready-made templates from sites like https://themeforest.net/
They are made by professional designers and polished by the authors to a shine under the influence of the community.
