HTML with CSS in pages content

Hi,
I have some WP static pages and I want to list a kind of downlaod links on one page. So, I created some CSS for file title and file meta info.

The question is should I create special template page or is it good practice to put HTML + CSS into the page content (write it to form when editing WP page).
Certainly, it is common practice to put HTML tags into posts and pages content, but what do you think about putting something as follows:

<h4 class=”filetitle”>My File 1</h4>
<p class=”filemeta”>Version: 1.0
…
<h4 class=”filetitle”>My File 2</h4>
<p class=”filemeta”>Version: 3.0
…
<h4 class=”filetitle”>My File 3</h4>
<p class=”filemeta”>Version: 1.4

Thanks for your any advice.
Cheers
