Recently Google+ and Facebook have added a nice feature that when a user first logs in and there are new features available it displays it as a demo mode of some sort highlighting the element in question and darkening or changing opacity on the rest of the screen as a means to focus on that element. It also shows step by step tooltips for the demo.
Does anybody know of an open source script or jquery plugin that does this already?
They basically block the UI and show an overlay on top of the whole page. You can try jQuery blockUI plugin it will help you block the page and then you can show an overlay on top of it.

I don't know of one, so I made one: http://jsfiddle.net/minitech/A9AAa/
It's pretty simple, call spotlightOn and pass the element on which the "spotlight" should "shine" as an argument. Call spotlightOff to turn the spotlight off.
It should degrade gracefully.

we are using the Revolution Slider and wordpress, both in newest versions.
Actually we want to set this : http://vincentgarreau.com/particles.js/
as a background animation.
We used the code snippet you get when you hit code pen in the upper right corner.
The html part was added as a layer.
css and js part were added to the custom css / custom javascript field in the slider settings.
The problem:
When the page starts nothing happens. No animation appears. If I hit the area with a right click and press q (in firefox) the animation starts to work.
So I guess it is about a loading issue!?
Can anyone imagine a solution with the given base?

Do you check your console? How have you integrated the script? After testing, it works for me. The piece of javascript must be placed at the end of the page, or create a function wich starts when page is loaded.
I'm trying to resolve a problem that I encountered with the creation of a tooltip interface in a website I'm developing. I constructed the tooltips with help of HTML, CSS and JavaScript. The script is pretty simple as you can see in the fiddle underneath, and is based on a toggle behaviour, on witch a trigger element open a pop-up tooltip.
jsFiddle
Now! My problem is that i can't figure out how to place the trigger on the top of everything so they are not hidden by the pop-ups! Let me explain. Since the pop-up, even when they are off, sometimes cover the trigger elemets they (the triggers) just result not clickable. is like they are hidden behind invisible pop-ups. Here is a link of how is right now online.

I hope you can see the problem! Does anyone know how to resolve this?
You've changed the .pop-ups to "block" as soon as it initializes. $("div.pop-up").css({'display':'block','opacity':'0'})
If you want to show/hide, I would recommend using .fadeIn/.fadeOut: http://api.jquery.com/fadein/
I'm looking for a JavaScript library, pure JS or JQuery-based, that will allow me to create a slider similar to AnythingSlider or http://basic-slider.com/demos/. The most important feature I'm looking for is the ability to dynamically append new slides and then trigger a transition to it. The ability to transition to any slide is also important.
Most libraries I've investigated require that you append the slide to an element then retrigger the slider. This is fine however most scripts I've tested change the current slide position or there's a noticeable change in the elements on screen that disrupt the user experience.
Thanks.
I'm a personal fan of bx-slider. It's pretty basic, but it works really well. http://www.bxslider.com/
It just requires a basic div set up, and it's a plugin, so just call it from $('#myID').bxSlider();
Have you taken a look at the Nivo Slider? I have used this before and have never seen the problem you are describing (with retriggering the slider).
So, I am developing the first serious web site. I want to implement the following scenario, but I need guidance and advice. There is a button <input type="submit"> on my web page. When the user clicks it, I want it to open some HTML content which will be shown on top of all page content (and positioned centrally, but I don't care about that detail at the moment). It should act very similar to the way the photos are viewed on Facebook. When the user clicks the photo thumbnail, the photo opens on top of and across all page content.
Now, I've implemented this already, but I think that my approach is not recommendable, as it looks a bit clumsy to me, especially when I think about the maintenance of the site:
I added a <div> as the last element to the <body>; it is positioned absolutely and collapsed and serves as a container. When the button is clicked, that <div> is filled with the content and the state is changed from collapsed to visible.
I would very much appreciate if someone would like to share the standard methods used to achieve this effect and opinions . I am guessing that AJAX and jQuery should be used heavily for this (I used pure JavaScript in my design described previously). I am looking for some code samples and resources. Thank you so much.
What you are looking for is a modal dialog and not a pop-up. Pop-ups are new windows, while modals are HTML elements that block the page behind it for emphasis on forward content.
One way is to have a <div> appended to the body, usually to the end of the body and have it positioned absolute. That div will have top, bottom, left and right zero to stretch to fit the viewport. Within that div is another div that is also positioned absolute, relative to the parent, viewport-fitting div. Positioning is up to you, but usually it's centered using a formula:
center = (total length - modal length)/2
Content is up to you. You can have the content already loaded and hidden in the DOM which you can just display later. Or load the content via AJAX if you wish.
jQuery already has a modal plugin in the jQueryUI suite which you can use that packs a lot of methods to add and customize.
There are a lot of approaches out there. You could use jQuery UI (http://jqueryui.com). But I like the approach Twitter's Bootstrap is taking: http://twitter.github.com/bootstrap/javascript.html#modals
This is a very clean setup and you can load the content via AJAX with a little selfwritten function. You don't need to write everything yourself because there are plenty of plugins out there. And the bootstrap modal plugin is standalone so you can just use this one.
I like to use it and generate the content div with an AJAX request.
You can position: absolute; the popup box and set it where on the screen you want it. Then use z-index to put it over the content.
Here is a demo: http://jsfiddle.net/e6BEu/
I believe what you're looking for might be Lightbox-like? It could give you some ideas at the very least.
Edit: Or this one which supports text and such.
Is there a good Javascript library for generating an automatically scrolling list like the "Top Tweets" on the Twitter homepage? Preferable as jQuery plugin. It should also support AJAX functionality (to add new list items dynamically).
As we were not really satisfied with the existing solutions we implemented one from scratch. Our solution is a fully jQuery UI compatible ticker plugin (also compatible with their theming framework) and fully unit tested. We didn't yet have the time to test it under every browser, so feedback is welcome (for problems please open issues on the below Github project site).
A special styled demo (Twitter like) is available here.
The main main repository can be found here (ticker branch). There are several options to customize the ticker (documentation at the above mentioned Github repository).

Here is a nice solution: Scrolling List
Try http://www.htmldrive.net/items/demo/38/Multi-purpose-slideshowtext-scrollerimages-scroller-jquery-plugin
That is the best solution I was able to find:
Scrolling List
If you want to write your own, make a div of fixed width/height, with overflow: hidden, then create another div inside it, with the position: relative property, filled with content from your feed (twitter posts, or similar, etc). Then, when the page loads just make the inner div's top: CSS value change (if you want the list to scroll up, the top value should decrement from zero).
I doubt this helps, but it is quite a good, simple way to get a scrolling without using a jQuery plugin.
