How to Submit Suggestions to the CSS Spec

How do I submit suggestions to the CSS spec?

You should probably subscribe to the www-style mailing list of W3C

This mailing list is for technical discussion on Cascading Style Sheets (CSS) and its specifications. All posts to this list must be about the development of the CSS specification itself. This list is also the preferred place for discussing working drafts that are published by W3C's CSS Working Group.

Who do I make CSS development suggestions to?

The W3C has a Participation FAQ that you might be interested in, but if your idea is development-related, does it really need to be a part of the specification? Or is it the sort of thing that developers of popular (CSS-related, web development) tools could simply add support for?

Rather than going directly to the W3C, I'd suggest first trying to get some more exposure for your idea. Write up a blog post describing it, submit it to some popular sites like A List Apart, Hacker News, or Reddit -- basically, get as many eyes on your idea as you can.

If your suggestion really is a good one, it'll help to gain momentum by getting a lot of attention. Or, if it's a bad idea, you'll quickly find out by having people "review" it. You'll likely get some good suggestions to improve the idea, and you'll definitely spend your time better getting peer feedback than somehow trying to singlehandedly champion it to the W3C.

How handle the CSS3 Spec. in a useful way?

As long as your site degrades gracefully there's nothing wrong with using CSS3 now. Afterall, if a browser does not understand a particular CSS rule it will just ignore it:

#foo {
    border:1px solid #000; /* shown by all browsers */
    border-radius:5px; /* shown if browser understands border-radius */
    -moz-border-radius:5px; /* Firefox only */
    -webkit-border-radius:5px; /* Safari and Google Chrome */
}

As long as the site does not look broken in browsers that don't support the CSS3 rules you want to use then you should be ok progressively enhancing your site in the browsers that do support them.

Where I can get all CSS elements and properties spec reference listed as to each HTML(XHTML) tag?

This site has more info and resources about working with this tag, browser support, and build resources: https://caniuse.com/#feat=details. It may give you some more paths of research.

Serving CSS from a static domain

When you pull the css from a static domain, relative URLs in the CSS will point to the very same domain. So you can just use relative paths and serve both css and images from that domain.

rails tutorial expected css title with text to return something

I figured out the problem. Where I say '#{page_title}' it should be "#{page_title}". Double quotes instead of single quotes -_-. Can someone tell me why that works? Especially because I have stuff like 'Sample App' in the same have_selector checks and that doesn't throw any kind of error. Hope this helps someone in the future at least.

CSS spec: properties specified multiple times

It cascades to the last valid declaration.
So - color:'green' would win.

Again, cascade wins. border-top-width would otherwise be styled independently, but border-width: would win to apply 5px to All.

How do you structure css files for a web project?

A css file for each .aspx page seems to defeat its purpose, namely reusability, etc. I suppose if each page is really that unique from a style perspective, maybe it's necessary, but I'd work on getting away from that format.

I usually have a master css file, then perhaps additional ones for other major portions of my site (such as a private administration section, etc.)
