What program can immediately see exactly where the indents in the layout come from?

Question

Design

Hello.
I inherited a Bootstrap 4 template)) and I just can’t get rid of one indent on the left, and I don’t understand where it comes from, because there are a lot of p-3 ml-2 and the like + a file with custom styles for classes. ..
In general, I thought, maybe there is such a program that can visually show me where exactly this indent comes from?
Some kind of browser plugin or something.
Through the browser inspector, I can not understand - there is a whole sheet with these selectors ..
Thanks in advance.

Answer 1

I don't remember any indentation issues that couldn't be localized through the chrome developer tools. You can always hover over an element and examine its box model on the right in the developer tools.

Answer 2

There is a Computed tab, filter there and see
