CSS class equivalent for LaTeX

Question

I am trying to figure out if there is a way to apply the CSS methodology to the LaTeX template I am building. What I would like to do is to have a set of classes that apply a specific style treatment to the bracketed words. For example:

If I have three paragraphs of text, I want to have all of the paragraphs have [0.5cm] of spacing after the last line without having to add \\[0.5cm] after each paragraph.

Is there a LaTeX equivalent of defining the treatment for all paragraphs in the preamble so that it cascades throughout my document? The equivalent of:

<style> p {padding-bottom:0.5cm} </style>

I want to be able to specify multiple version of these CSS-like LaTeX classes throughout my document, so I don't need a specific solution. I need help understanding how to add custom labels/names/classes to the preamble and an example of how to use them in the document itself.

Thanks!

It sounds like you want to define your own environment. Below is an example from LaTeX wikibook.

Put this in your preamble:

\newenvironment{king}
{\rule{1ex}{1ex}\hspace{\stretch{1}}}
{\hspace{\stretch{1}}\rule{1ex}{1ex}}

And then use the style in the document:

\begin{king}
My humble subjects \ldots
\end{king}
