How to design for a web application?

Question

Design

For the graduation project, it was necessary to make a web application by order of the office.

I don't have design skills, but I have a sense of style.
In general, how to deal with the design of the application on your own (for free)? In principle, this is a diploma and no one cares what it looks like, but it’s not like you want to show the eye-catching frontend yourself.
Are there any options to relatively quickly, without special knowledge, make it more or less beautiful?

Answer 1

Find on the Internet the first site you like with a design and make it in the same style and color scheme. Or for a scarlet flower: choose a set of harmonious colors and drink from scratch. The first option is faster, you saw how beautiful it is and even better at home.

Answer 2

Look on YouTube for a detailed step-by-step lesson "how to draw an application design".
Watch, repeat, change your colors/pictures/icons.
Graphics can be taken on free drains.
