Public service announcement: Each time you name a proprietary characteristic “CSS3,” a kitten dies. Any -webkit- characteristic that doesn’t exist in a specification (not even an Editor’s draft) is just not CSS3. Sure, they’re generally evangelized as such, however they aren’t a part of CSS in any respect.

This distinction is just not nitpicking. It’s essential as a result of it encourages sure distributors (*cough* Apple *cough*) to bypass the requirements course of, implement no matter they give you in WebKit, then evangelize it to builders as the perfect factor since sliced bread. The shiny new toys dazzle us and we begin selling them too, contributing to the echo chamber.
In our eagerness to make use of the brand new bling, we regularly neglect how many individuals fought up to now decade to allow us to write down code with out forks and hacks and anticipate it to work interoperably. You probably have been on this area quite a lot of years, you certainly do not forget that it wasn’t at all times like this. The explanation we now have this comfort is internet requirements, arduous gained within the Browser Wars.
You is perhaps stunned to listen to that internet requirements did exist in the course of the Browser Wars too. The W3C was based in 1994. Nevertheless, authors didn’t care, and had been completely keen to embrace proprietary extensions. In consequence, browsers didn’t hassle a lot with internet requirements. Does this remind you of one thing? The proprietary options of right this moment aren’t any higher than ActiveX and IE filters. Their solely distinction is best PR, as we haven’t confronted the implications but. Imagine it or not, these options had been additionally welcomed with pleasure again within the day.
Sure, typically browsers give you great things that does get standardized ultimately (XMLHttpRequest, Drag and Drop API, contentEditable, Internet fonts, to say just a few). Nevertheless, nothing prevents them from innovating and following the requirements course of. Nothing prevents them from developing with one thing cool, proposing it to the suitable W3C Working Group, and enhancing it via collective suggestions earlier than dashing to implement it. If Microsoft had completed this for the Drag & Drop API, it wouldn’t be such a PITA to make use of.
Proprietary options that haven’t been via the requirements course of normally endure from poor design, even when the overall thought is nice. For example, CSS gradients had been an ideal thought, however -webkit-gradient() was a verbose, error-prone mess. Internet fonts had been an ideal thought, however requiring .eot recordsdata was not. The requirements course of doesn’t solely assist with interoperability, it additionally helps enhance the design of each characteristic, as a result of higher quantity and variety of opinions.
So, that are these notorious options? In CSS, a number of the hottest ones are:
-webkit-box-reflect-webkit-text-stroke-webkit-mask-webkit-background-clip: textual content;-webkit-text-size-adjust-webkit-tap-highlight-color-webkit-text-fill-color
Not each prefixed characteristic is proprietary. A few of them are simply experimental implementations of options included in draft specs. Which brings us to your subsequent query.
“How do I detect whether or not a sure characteristic is proprietary?”#section2
A means that works for me is to go looking in Google for the characteristic (in quotes) and append website:w3.org to the search time period, with a purpose to solely search inside the w3.org area. Two examples:
As you’ll be able to see, one of many very first outcomes for the primary characteristic is a W3C specification. The outcomes for the second are merely discussions on mailing lists, which signifies there isn’t any specification for it but.
“How can I assist?”#section3
The straightforward rule of thumb is to keep away from proprietary options altogether. Don’t use them, don’t evangelize them, and most actually, don’t rely upon them. Nevertheless, I perceive that this is perhaps extra simply stated than completed. In case you can’t fully shut proprietary stuff out of your life, listed here are just a few pointers I’m certain you’ll be able to comply with:
- Ensure their utilization complies with the rules of progressive enhancement in order that the design works effective with out them.
- Don’t evangelize them or, if you need to, be certain that to clarify that these options are proprietary and what meaning.
- If you need to use them in your code, add a remark about this. One thing like
/* Warning: Non-standard */would suffice. Many individuals study front-end coding by viewing the supply of present web sites. Even in case you don’t give talks or write tutorials, you’re most likely not directly educating of us with every bit of code you set on the market. - Name out articles, talks, demos, and so forth. that evangelize these options with no warnings, or that solely use a single vendor’s prefix (which can be a really major problem). Or, even higher, repair them your self, if doable.
“How can I assist standardize a characteristic?”#section4
If you end up needing a proprietary characteristic too incessantly, take motion to standardize one thing comparable. A sequence of steps I’d advocate is the next, most of which might be utilized to new proposals on the whole:
Step 1: Analysis standards-compliant alternate options#section5
Initially, analysis standards-compliant alternate options. They may have worse or non-existent browser help, however a minimum of you’ll know what to push for. You possibly can even add it as a fallback, so that you simply don’t shut different distributors out even after they implement this characteristic.
You possibly can even assist to hurry up implementation, by submitting a bug within the browsers that don’t help it. Ensure to seek for present bug experiences first. If it’s reported, you’ll be able to nonetheless present that it’s essential to you, by writing a remark (be well mannered!). Browsers take writer demand into trương mục when prioritizing which options to implement. Present them {that a} sure characteristic issues to you.
Step 2: See if the characteristic is already proposed#section6
The W3C discusses which options so as to add and how you can tweak them to perfection of their mailing lists. There’s one per Working Group (WG), and typically extra, as Working Teams can collaborate in growing options that have an effect on a number of applied sciences. For instance, the CSS WG makes use of the www-style mailing listing and the SVG WG makes use of the www-svg mailing listing. Nevertheless, for options that have an effect on each CSS and SVG, there may be the public-fx mailing listing.
Earlier than you submit in any of those lists, please seek for prior dialogue of the difficulty. Each minute a WG member spends responding to duplicate strategies is one much less minute spent growing internet requirements. To go looking the archives, you’ll be able to once more use ol’ mighty Google. Kind your key phrases as you usually would and append website:lists.w3.org to your search question.
In case you see that the characteristic is already advised, however the dialogue has stalled with no decision, you’ll be able to reply (as soon as!) to convey it up. Please keep away from coming off as impatient or irritated in your e-mail. Hold studying the dialogue for concepts on what so as to add that somebody hasn’t coated already.
Step 3: Suggest the characteristic#section7
Attempt to embrace as many related knowledge as doable.
Some sorts of knowledge that you could possibly embrace are:
- Use circumstances the characteristic is beneficial for. This is essential. No WG desires to standardize issues which are going for use in edge circumstances solely. Present that what you’re suggesting is widespread. A helpful method to collect such use circumstances is to google for the proprietary characteristic and see what persons are utilizing it for.
- Your expertise from utilizing that characteristic. What you want, what you’d change in the best way it really works, how may it’s generalized, and so forth.
Additionally, determine which specification it’s for. Yow will discover a listing of the CSS specs right here. Then prepend the title of your thread with that specification’s ID in brackets. For instance, if it’s for Values & Models, prepend it with [css3-values]. (The ID of every specification might be present in its URL.) This ensures that the editors of that specification will discover your thread extra simply, and tagging helps everybody to comply with the event of sure specs they’re considering.
One other factor to remember is that new options don’t get added to specs which have reached, or are about to succeed in Candidate Advice standing. After all this is applicable to each standing that comes after that, i.e. Proposed Advice and Advice. For instance, in case your suggestion is about including a brand new selector, don’t recommend it for Selectors Stage 3 (ID: css3-selectors), which is in Advice standing, however for Selectors Stage 4.
If you wish to know extra about how the requirements course of works, you’ll be able to learn fantasai’s wonderful article sequence “Contained in the CSS WG.”
“All that is arduous and boring!”#section8
The identical might be stated for recycling vs. throwing every little thing in the identical bin. Sure, it certainly is more durable than simply utilizing proprietary options and calling it a day. Nevertheless, in the long term it’s in everybody’s greatest pursuits, together with your future self.
Thanks loads to David Storey, Sylvain Galineau, and Eric Meyer for his or her suggestions.
