This is a simple CSS "Framework" that lets you create and manually layout printable HTML documents. Basically the printed version will look exactly like what you see on screen. You can create complex layouts using CSS without worrying about them getting botched by your browser's print settings.

Additionally, there is a very basic LaTeX style formatting option that let's you create pages that will look like and seemlessly integrate into LaTeX documents. See LaTeX's pdfpages package. This is mostly possible due to TeX's Computer Modern Font being available as a webfont. See Using Computer Modern on the web. You may also want to include MathJax for displaying mathematical formula.

• I assume you know your way around HTML and CSS. Otherwise you should probably find another (easier) way to do whatever it is you are trying to do.
• A sensible, up-to-date web browser is recomended. I have only tested this in Firefox 29+ but I assume that latest Webkit browsers will work fine as well (feedback is appreciated).

• Look at the example.html file. The easiest way to start will be to modify it. You can copy-paste div.page to add more pages. Make sure you leave the document structure intact and page.css is linked in your document's head.
• Put your content inside div.page-inner. Go Nuts.
• Add the appropriate CSS classes to specify what paper format you want to use.Look inside page.css to see what paper formats are available. The default format is DIN A4. Feel free to suggest more formats!
• Add a .latex class in your document for things that should look like LaTeX. If it all should look like LaTeX, just add it to the body tag. Make sure latex.css is linked in your document's head and look inside to see what classes you can use.
• Open the HTML file in your browser (see requirements).
• Use the browser's print function. Make sure to check a preview first or use a 'print to file' feature.

Consider the following scenarios

• You want to create a short (1 or 2 pages) document, like a handout or a cheatsheet.
• You are trying to create something that looks like LaTeX but LaTeX keeps botching your complex box layout. You know you can achieve it using CSS.
• All other alternatives have failed you (office suite, InDesign, Scribus).
• Maybe you want to automate stuff like generating a table or even create graphics with something like D3.js.
• Something else I haven't though of yet.

• Don't use this to write long, multi page documents. That's what LaTeX is for.
• Don't expect any magical auto-formatting. That's not what this is.
• Don't use this because you don't know LaTeX. If you can use this then LaTeX will be easy enough to learn for you.

• This Software is provided as is, yada yada. I don't take any responsibility for things you manage to break or waste by using this. If you print out a thousand pages and then notice something is slightly off, that's on you.
• You may use and modify this however you want. It's free as in free software and free as in free of charge.
• Don't distribute it claiming you created it yourself.
• If you create something cool with this, show me, so I can feel warm and fuzzy inside.
