writing

Hello

I'd like to ask about writing style.
One textbook says that the first paragraph starts the line without indentation. The second paragraph makes white space at the beginning. Is this true? I saw some first paragraph have white space at the beginning. Is there one rule how to start? How about the second and third paragraph? How many letter should I omit as indentation?

I'll be happy to get some guidance.
Thank you.

Many say that after a heading there's no need to indent because the heading makes it clear. However, this isn't a hard and fast rule and some do. Newspapers tend to indent because of the column width- it makes it clearer. If you look hear, you'll see that different people approach the issue in different ways:

I think as a basic guide, try to make it clear. In writing, I tend to leave a space and not indent.
