I was browsing through random websites when i came across this site called canva.com and its homepage interested me a lot. It has a blurred background and when you hover through it, it becomes sharp. I tried to check out its source code but, could not figure out how they did it?
I tried to check the background image when the mouse is hovered and every time i check it, it is a different background image for different position. I don't think that the designer made all possible images and uploaded, that would not be efficient perhaps. I think that the images are dynamically generated.
Anyone else have any idea as to how it can be done?? Please check it out.

The closest thing to what I am looking for is this:
http://www.qmatica.com/DataStructures/Trees/AVL/AVLTree.html
Notice how it lets the user insert or delete nodes by clicking on buttons.
The problem with the above link is it is implemented in Flash, not Javascript.
Also, instead of clicking on "Insert" or "Delete" buttons I want the user to be able to drag and drop nodes into or out of the tree.
I would appreciate it if somebody could let me know of any Javascript vector graphic libraries that do something like this.
Do you need something like that tree? I have used nestable for the same purposes and find it better looking and usable. Check this out http://dbushell.github.io/Nestable/

I'm working on a project where the user should be able to hover over / click arbitrary HTML elements, and the selected element is recorded programmatically. The desired functionality is similar to Chrome / Firefox's "inspect element" functionality.
Before rolling my own, has anyone found a good open source, cross-browser implementation?
Thanks!
Perhaps this is what you are looking for:

You would need to fork the project and modify it to fit your needs, but the "inspection" functionality already works.
You can see how it is used by Mozilla in here:

I would like to embed a smartphone in my website and display webpages in its screen. Everything would be in html(I prefer 5), css and js and I dont know if there is any plugin that does this because I have no idea how to do it.
Thank you in advance
Insert an image of a phone on the page, with the correct dimensions so the screen is big enough on the phone.
Make a div with the screens dimensions and position it on top of the phone image.
Insert an iframe in the div with both width and height set to 100%.
Use a predetermined URL in the iframe, or set one dynamically with JS.

I have a Mindtouch powered website that seems to hate jQuery. If I load it up it comes in conflict site some CMS native JavaScript and makes my site navigation stop functioning.
I have been looking for days for a nice lightbox written in JavaScript not jQuery that will automatically lightbox all links to images that have an image as content.
<a href='someimage.jpeg,jpg,png,gif'><img src='thumb.jpeg,jpg,png,gif'/></a>
If anyone can point out at least one plese.
Google was not good help for me as all results are jQuery based except some ancient ones that just look terrible.
Shutter Reloaded
Not very animated but very nice lightbox.
I made some changes to the bottom buttons but I love the real full-screen feature.
More importantly it's small compact and no jQuery required.

Because it is not possible to force the iPhone to bookmark a webpage, I want a little arrow/bow to drop down to notify people to bookmark my mobile web page.
For any future viewers I would like to add http://cubiq.org/add-to-home-screen
I don't think your question is limited to the iPhone. There are several implementations of "sliding" panels/boxes implemented in jQuery.
Check out this one. It's a login panel that slides when you click it, but I'm sure you could adapt it to be a ribbon that slides down after the page is rendered.
