I'm trying to create a gray "frame" (see pic below) around a google map, to try to convey the concept of an area of focus, as oppose to a point (which is usually represented with a marker). Note that this is not an overlay, that is, the gray "frame" should not move when you drag the map.

It appears that only option is to "subclass" GControl to create a custom control. I have 3 questions
1) First of all, is GControl subclassing the best course of action?
2) In my example, the canvas (div) where map renders can change its size (i.e is not fixed width). Do I have to delete and add custom control when canvas changes size? See docs http://code.google.com/apis/maps/documentation/controls.html#Custom_Controls on how to create a custom map control.
3) Now, how to do it. Naively, I thought I could create a table with 3 columns and 3 rows, and set display: none for the cell in the middle. But that doesn't work. I've also experimented with clipping, that didn't work either. My css skills are quite lacking, so there must be way to do this more elegantly than adding four rectangular gray divs. If I wanted to add an inner border, with divs, I would need to paint 8 then. In a nutshell, what's the best way to create a "hollow" rectangle?
Thanks
P.S. This is my first entry to StackOverflow. Just discovered it. It's impressive how well SO is put together.

I inherited Sprite and I want to put inside TableView but when I add inherited Sprite to scene table is not visible but all others sprites added to inherited sprite are visible ( I checked it creates cells, position and z index are set right, when I add TableView directly to Scene it is visible).
I'm able to add a TableView to a Sprite in Cocos2d-x v3.6, but it's a little hard to say exactly why yours isn't showing up. Here are some things to check:
Have you added the TableView as a child to the Sprite via addChild?
When you add the TableView to the Sprite, is your DataSource set properly? (This seems to be the case given your question).
Are there positioning issues when you add it to the Sprite due to the anchor position(s) of your Sprite and it's parent(s)? It could be the TableView with incorrect positioning, or it could be the TableViewCells themselves. Remember that when you add a child to some Node, its anchor point is Vec2(0.5, 0.5).
You're not forced to override cocos2d::Size cellSizeForTable(cocos2d::extension::TableView *table), and if you don't have cell heights, the cells might not show up.
Try "dumbing down" any logistics you have and follow the code in TableViewTestScene.cpp, which is part of the cpp-tests. (cocos-directory/tests/cpp-tests/Classes/ExtensionsTest/TableViewTest)
Last resort: Try doing something silly like giving your table and cells a large height and width of 500-1000 pixels each. Give them an absolute position somewhere in your Sprite. Give each of them a Label that says "Hello, World!" and see if they show up.
It might be helpful to see your applicable code, too.
A very late edit: I realized today that it seems as though Layer objects (and thus TableViews) always have an Anchor Point of Vec2::ANCHOR_BOTTOM_LEFT. Could this be your issue?
This seems dissimilar to the accordion functionality provided by bootstrap.
To give an example, let's take the "how to format" info starting me in the face right now. I'd want it so that it only displays up to X pixels deep, and then stops until expanded. So it might look like:
and then, once expanded,
I happen to be using bootstrap. Is there a bootstrap native or other HTML solution to create this kind of experience?
Assume that the thing that I only want to show of is a single element, such as an image, rather than a series of text. This means a solution like min-height:50px and overflow:hidden won't work, as it will simply hide the entire image rather than part of it.
We can use jQuery .height() to accomplish knowing the rendered height of an element then making conditional modifications.
Documentation and examples for jQuery .height().
A combination of height and overflow in combination with the toggling of a class should work here.

WHAT: I want to have an hover image for all the different parts when the mouse go on it. (event/brand/website/print/UI/VIDEO)
PROBLEM: The images are overlapping and the mouseover start when i'm on the transparency of the png.
SOLUTIONS I TRIED: Imagemap to detect the zone and then put javascript code inside the AREA. doesn't work.
Imagemap to detect the zone, put an id in the AREA and use a separated JQUERY with .hover(function(). doesn't work.
Use z-index: impossible because there will be always an image that will hide the one under.
QUESTION: If I can't use ImapeMAP to select my zone and use CSS or JQUERY, how can I do ?
Thank you so much for your help!
Might be too late but the exact case can actually be solved by a class I wrote around 3 months ago. It allows you to check whether you're on a transparent area or not and also check for other elements behind the transparent area, this allows to overlap multiple transparent images and correctly jump from one image to another at the correct point.

I have to implement this grid of divs. It won't change often, but it may at some point (meaning a box may be removed, and another resized). Each black box will eventually contain an image or a word, but that's not important.
How do I pull this off? Is there a more elegant way than by absolutely positioning every single box and manually entering every X/Y/width/height?
A grid based approach would be my recommendation.
Something like: http://960.gs/

Usless Background Info
Hello, all. This is my first post here, but I often come here for help.
I am an amateur web designer and have been in web designing for almost a year now.
The Problem
My question is about CSS3 transforms. I have a small, circular element in the center of my page that transforms successfully when I hover over it. I have a larger circular element that is, by z-index, underneath it. The larger circle also has CSS3 transforms coded in the CSS, but will not transform, or even triggerd when hovered over. Both circles are overlaid, with the smallest on top, to create concentric circles.
My Attempted Solution
One word: Z-index. I have tried putting the larger circle on top, which works fine. The problem with this is that the smaller circle no longer triggers...
The Result I Want
I would like for the circles to remain in their 'concentric' positions and for the larger circle on the outside to transform by :hover. Is it possible to have an 'alternate trigger'? e.g.: in JavaScript, I can trigger an animation by hovering over any element that I specify. Is this possible to do in CSS? Can I hover element (I), and change properties for element (II)? If I cannot do this, how would I go about triggering animations for both circles, by hovering over only one? I am trying to stay with pure CSS/HTML, but I will accept JavaScript answers.
Last Notes
I hope I have provided ample info for a decent answer... Here is a screenshot: http://i.stack.imgur.com/WPj62.png
The circle with the infinity sign is the smaller circle element. The larger circle with the faint border around the screen is the other element.
EDIT:
Something's still not right, please take a look at the full code posted here: http://cssdesk.com/eJ8BH
If I understand your question, it sounds like when you hover over the small circle, you want both the large and small circle to transform, correct?
The easiest way is likely to use javascript for this. If you are using jQuery, it's even easier:
$('.littleCircle')
.hover(function(){
$(this).addClass('myTransformationClass');
$('.biggerCircle').addClass('myTransformationClass');
})
UPDATE: Some further examples based on follow-up feedback.
Here's what I'd do. First, give all 4 related elements a class so you can grab them via jQuery. For the example I use .rolloverSet
// grab all 4 elements and cache them
$rolloverSet = $('.rolloverSet');
// grab the one element that needs to have two classes
$otherElement = $rolloverSet.find('.otherElement');
$rolloverSet
.hover(function(){ // we'll add a hover event to each element in the group
$(this).addClass('myTransformationClass');
$otherElement.addClass('myOtherTransformationClass');
})
.blur(function(){ // remove the classes on mousout
$(this).removeClass('myTransformationClass');
$otherElement.removeClass('myOtherTransformationClass');
})
You do not need jQuery for this. You need to apply :hover on the parent element of the concentric circles and then apply the animation to its immediate children like this: http://jsfiddle.net/nimbu/taqr4/
Things I changed:
Updated to use shorter transitions, animations property
Added moz, o, unprefixed properties
Removed -webkit- from border-radius
Gathered common properties of concentric circles to prevent repetition
Fixed incorrect background-color (#00000000)
