I am trying to use a bootstrap theme (Worthy) as the base for a website. The theme works very well, however I am having problems adding this scrolling timeline feature to it.
Here's what I know:
I can get the demo of the timeline working
I can get the template working
I can get the timeline implemented in the template w/ the .css working
I CANNOT get the animations of the timeline working in the template
I have traced the issue to one of the timeline's required files, namely a customized version of modernizr. (The template uses the standard version of modernizr). When I remove the the reference to the custom modernizr, the site generally works, but the timeline animations do not. When I add the reference to the custom modernizr back in, all of the site's content disappears.
Does anybody have any suggestions of how I can go about diagnosing and debugging the problem? I know that I have not posted any code, as I'm not sure what is and is not relevant. If somebody can please point me in the right direction, then I can follow up with more targeted questions.
UPDATE: I have also tried removing the template's version of modernizr and only using the one from the timeline, but that also results in all of the site's content disappearing.
Thanks a lot!
Modernizr has an build tool that you can customize to be exactly what you need it to be. What you would want to do is get a list of all of the detects that you need, then build a new custom one that contains everything.

I'm trying to create a page similar to new google calendar landing page http://www.google.com/landing/calendar/
I'm using skrollr(https://github.com/Prinzhorn/skrollr) but I can't get the effect right, on google landing page if you do a small scroll it will send you to the next block and with skrollr I'm not able to get that navigation. Any ideas how I could reproduce that? is it possible to do with skrollr or you would recommend another js plugin?
Thanks!
In case you still haven't found a solution yourself, I've been tasked with doing a very similar thing. There are two ways of achieving this that I researched and choosing the right one mostly depends on the complexity of your design/expected result. Unfortunately I can't provide a link because the site won't be live for next couple of weeks.
This is what worked for me:
I used fullpage.js library to achieve 'full-page' scroll effect. You could also take a look at onepage-scroll.js and see which one fits you most - they don't differ that much in terms of functionality though.
Benefits of using fullpage.js (among other things):
integration is quick and simple
allows a lot of customisation through options hash
provides callbacks when scroll to another section is triggered (before or after it happens)
enables you to manually trigger a scroll via 'methods'
works surprisingly good on iPad/iPhones. Probably on other mobile devices as well, although I can't fully confirm that since that
wasn't a requirement for my project.
Now when you've got section-to-section scrolling in place, what's missing is the animations. Considering that fullpage.js provides you with callbacks, it's as easy as adding a class when a transition to another section/slide happens and then using that class to trigger an animation of your choice through CSS. This is what worked for me without facing major problems.
For more advanced things:
If you're looking to build something more complex, then I strongly recommend that you take a look at tween.js. This is what google used on the landing page that you've provided in your question.
It's a very powerful tool hence it requires quite some setup + it moves animations to javascript, which might be a hassle. I would rather keep them in CSS where they belong and dont use javascript until I really need to.
FYI I also started with skrollr but it won't really work with 'fullpage scroll' because what it really does is disabling scrolling and animating body/html through translate. Skrollr bases it's behaviour on scroll event which will not fire if you use libraries I proposed.
EDIT:
It appears that you can actually use skrollr in par with fullpage.js. You can see the answer on how in it's FAQ site. Thanks to Alvaro for claryfing that! Even then, I wouldn't use skrollr unless you really need it for some advanced parallax scrolling effect - as said before, depends on your needs though. :)
Let me know if you have any doubts or something is not clear in my answer.
Good luck!
I've built my mobile site using the jQuery Mobile UI but I now realize that I need some functionality to be different between it and my desktop site (datepicker dates should be longer on the desktop site, etc).
I've looked into Modernizr and matchMedia to help me load separate js files but I can't figure out a nice way for it to work responsively. Modernizr only works (unless I missed something in the doc) on the initial load and I'm having problems with matchMedia executing multiple times as it crosses the min/max-width threshold. It works sometimes but the trouble is in adding/removing the separate js files. On top of that (but not a huge issue - I don't think), Chrome fires off an error when loading scripts into the DOM from another script.
Would the best thing be to write one js file and then add a listener such as $.mobile.media("screen and (min-width: XXXpx)") to the body's width, changing my needed values?
I may be making this too hard for myself, or missing something obvious because I'm trying to keep HTTP requests and site size as small as possible, but I can't figure out a good solution for this.
Thank you!
Lightning Round Bonus Question: Is it good practice/proper to keep all of the jQuery Mobile styling (data-role data-id data-theme) after switching to the desktop site? It looks awfully .. awful for someone only viewing it on a larger screen.
IMHO, the best approach would be to introduce a couple of flags in your javascript, like "isMobile", "isTablet" or "isDesktop", that would be set within a method attached to the "pageinit" event of your webapp. Later on, you could check that flags to act accordingly with the proper version in the specific parts of your code.
The way you can check that flags depends on your architecture. In the project I am working right now, I extract that information from a class attached by the back-end on the body of the page, but that's because we have that info. You could try to use a library like Harvey to observe the media-queries that would be trigger, and set the flags accordingly. I don't think that your options ends here, but I am afraid I can't help you more!
Let me start by saying I have read plenty of questions and blog posts relating to the use of combinations of backbone/jQuery mobile and comparisons of backbone/Sencha, and have actually had my head in this space for some time but still haven't found quite what I'm looking for.
I'm very familiar with Sencha and have used it for wrapped (phonegap etc.) apps in the past, and I really like it. However for a smaller code base for web projects and more control over browser compatibility and various other reasons it's not quite appropriate for certain tasks.
When I start trying to engineer mobile (but also desktop and tablet) backbone webapps from scratch I find I miss three key things
General mobile 'init', filling the screen etc. (although this is the easiest to replicate)
Tabbed, iOS-style, navigation (of course I can roll my own, but it seems silly)
Scrolling - both scrolling a piece of content, but especially the carousel and how the carousel is linked to the tabbed interface
I'm not massively bothered about mimicking each device's native OS style throughout the app, and in fact would prefer to (whilst following some sensible conventions) make them look a bit different.
Ember has flame and I've used that before, that's kind of the thing I'm looking for.
I know I can build up a toolkit of jQuery mobile, custom script, jQ plugins/iSroll, CSS libraries, backbone UI etc. and do like the idea of compiling my own 'stack' but for some reason it just doesn't feel right.
So, to bring this back around to more of an actual question. I guess I'm looking for ideally a single project that isn't specifically linked to a library - and in theory could run on it's own on a statically coded page if needs be (even though that wouldn't be the case for me now). Or perhaps some words from others who have been on a similar journey and perhaps ended up on the mix of libraries I mentioned earlier with why they decided this was the best solution.
I'm not looking to do anything too crazy, say something a bit like the old sencha oreilly example but using some carousels, and I'd cover the multiple devices and browsers with a mix of Responsive CSS and a bit of JS.
I'm going to continue looking at this myself too and report back if I find anything interesting
Cheers
EDIT
While looking into this, I realised its only really the carousel and scrolling that I really wanted from Sencha. I noticed that Cubiq has a nice slideview component that handles the carousel very neatly and with a small footprint. I found a stackoverflow answer about using this with the original iscroll for vertical scrolling. See my answer below for successfully using the two together
How to use iScroll4 with SwipeView?
This would need some tweaking to work appropriately on desktop. and I'd like to control it from a tabbed UI too. Anyway, I'm not near answering my own question but given this has had a couple of upvotes I'd post some of my thinking.
Quick edit
You can attach events for tabs to the slideview https://dl.dropbox.com/u/81328343/scroll/1.html but at the moment, it only animates for next/prev and not direct page (tab) access

Very big library of components.
I've used Twitter Boostrap with Backbone...
http://twitter.github.com/bootstrap/
What should be the best thing to do with Twitter's bootstrap css/javascript library?
link (online), clone, fork or download it?
I would like to always have the latest updates on my website but I would like to customize small things like width size of a the tabbed navigation feature, some colors, etc.
Fork it. You will be able later to easily update to the new version, and merge in case you changed something. I suppose you are using github, so also push watch button, so you will always be aware of issues, updates, fixes of this project on your dashboard. Also you will be able to contribute to that awesome project.
Don't link directly, because one day they will change something, and this could break your app.
Also I suggest to look at LESS, and not compiled CSS version of library, in my opinion it's easier to customize everything there.
Update:
Probably easily update was too strong expression, and was referred only to bug fixes and minor updates. In a case of major version updates with breaking backwards compatibility there couldn't be easy and perfect solution. In this case, only if you really think you need this update, you can create new branch, update twitter bootstrap there, and than start a painful process of fixing your code. With branches you will be able work on your main app with old and working bootstrap, while part of your team will refactor code to become compatible with the new version of the bootstap(even if you only one person on the project, it's also good idea to test new solutions in the test branches, to not mess up working code).
Recently I'm working with jQuery UI Carousel (1.0.2) on my Drupal website. So far so good, everything is working without a problem but I'm looking for a way to add some external controls. You know, those little dots beneath the images where the user can navigate from and pinpoint a certain slide.
I took a look to the JS file (you can see it here), but didn't find any proof of such a controls.
Right now, I was only able to write some crappy code who didn't work at all... (so I'm not gonna post it to save you some laughs :))
Anyone with some experience regarding this subject?
Thanks in advance!
I don't have specific experience with the jQuery UI Carousel module, but if you are using Views to generate the content in the carousel, you could always use Views Slideshow. It allows you to add a pager (either numbers or thumbnail images) to your slideshow (carousel).
