The digital age is rife with complexity. How can one be expected to remember every shortcut, bit of syntax, steps in every process of every digital device and software? You can’t. So we have begun compiling a collection of Cheat Sheets from around the internet to help you (and us) out.
Web development
HTML / XHTML
| Cheat Sheet/Reference | Format(s) | Source | Notes |
|---|---|---|---|

| HTML 4.01 / XHTML 1.0 Reference | html/interactive | W3Schools | - |
CoTradeCo tips:
- Keep it clean
Make it easier to read the source and make better web pages because of it. Choose formatting standards and stick to them. Are indents soft or hard? How many spaces for different syntax? Decide this in advance and you will be a lot happier later. - Use a doctype
This is to much to discuss here. See this doctype article at alistapart. - Close all your tags
Even tags that don’t wrap anything (img, hr, br) you should still close them to help improve rendering and even bots that are trying to read your page. Tags that don’t wrap content can be self closed (e.g. <br />).
CSS (Cascading Style Sheets)
| Cheat Sheet/Reference | Format(s) | Source | Notes |
|---|---|---|---|
| CSS Cheat Sheet | png|pdf | ILoveJackDaniels | - |
| CSS Reference | html/interactive | W3Schools | - |
CoTradeCo tips:
- Store external stylesheets in a central location
We have a directory named “stylesheets” where all external stylesheets go. This makes referencing external images and the style sheets themselves that much simpler. - Name ids and classes based on what they are
It is NOT USEFUL or extensible to name ids and classes based on what they look like. Instead think in terms of being/doing. Is the “sidebar”. Is an article “callout”. Is a “product_image”. Is “boiler_plate” text/container. Is “footer_funny_text”.
