Long Quotations
You can view a live demonstration of this snippet on Codepen, and even play with it a bit. The version I've provided fits a very sedate aesthetic but should be easily customizable for yours...
When I came to neocities, it was to create a sort of reminiscence website about a group/cult and my involvement with it. It’s called the Aristasian Reminiscence Project (touches on tough topics - not for minors). The sheer volume of text I had written - and quotations from primary sources I had to insert - made things complicated, particularly within the confines of HTML and CSS.
Perhaps you’ve got a similar problem, or just want to highlight large passages of text (rather than the small ones highlighted in the pullquotes snippet) to catch eyes. Either way, I thought I’d show (one amongst many ways) how to set up your CSS and HTML such that large passages of text within the documents are
Naturally, HTML has a native structure for a <blockquote> for us to work with, though, so we needn’t fiddle with a bunch of random <div>s. Here, as was the case in the pullquotes snippet, I’m using the <small> tag at the end of the <blockquote> element to hold the quote source.
I’ve added a (significantly larger) pale quotation mark silhouetted against the background of the quote itself in lieu of the two small ones. I think it looks nice, but would probably look just as good with a different sort of color scheme, provided it wasn’t too contrasting. I may do a version more suitable to contrast.
CSS
You'll probably want to change the colors and play with things a bit, since your site likely looks completely different than the demonstration here, which shows exactly what these colors look like. You may, for example, want to change the size or font of the giant quotation mark, or remove it entirely. I think it looks best with Trebuchet MS out of all (main) websafe fonts, but that's just me. I expect you'd use your own font within the actual blockquote text.
HTML
Rather straightforward, isn't it? the only really custom feature is the addition of the <small> tag as a way of showing the source of the pullquote, and perhaps even linking to it. The filler quote comes from Marcus Aurelius's Meditations for no reason at all, really. It was just available. In this example, the quotation is 80% of the page, as indicated in the CSS, and the text doesn't wrap around it; it's centered. All of that is controlled within the CSS. Be mindful that the <small> tag is here used to denote the source of the quote. If you, for whatever reason, don't need that - feel free to remove it, no harm done, just add padding on the bottom to compensate!
