Dont Indent First Line of First Paragraph using CSS - html

Question

How would I prevent the line indent for the first paragraph in a section?
This is very common for many academic formats.
Sample Output
Introduction
For the first paragraph in the section, there is no indent: Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. In eu mi bibendum neque egestas congue. A arcu cursus vitae congue mauris rhoncus aenean vel elit.
For all following paragraphs, there is an indent set by text-indent: Sed velit dignissim sodales ut. Nunc pulvinar sapien et ligula ullamcorper malesuada proin libero. Tristique et egestas quis ipsum suspendisse ultrices gravida dictum. Augue mauris augue neque gravida in fermentum et sollicitudin ac.
For all following paragraphs, there is an indent set by text-indent: Nunc sed id semper risus in hendrerit. Etiam non quam lacus suspendisse faucibus interdum posuere lorem. Ut porttitor leo a diam sollicitudin tempor id. Facilisis mauris sit amet massa vitae tortor condimentum lacinia quis. Sagittis vitae et leo duis ut.
Right now, I have the following code in my CSS
p {
text-indent: 50px;
}

Answer 1

You may want to use the css pseudo-class 'first-of-type'
p:first-of-type {
text-indent: 0;
}
As the css selector implies the styling will only apply to the first p element.

Answer 2

You can use CSS Adjacent sibling combinator like this:
p + p {
text-indent: 50px;
}
Run the code to see the result
p + p {
text-indent: 50px;
}

Answer 3

You are correct, don't indent the first line of the first paragraph. To attract the eye, use an initial cap (increases readership around 15%).
However, in best-practices typography, you should only use one or the other: 1) a space between paragraphs (not a whole space, mind you) and no indent
OR 2) no space between paragraphs and but indent the first line.
