Is it possible to wrap text around a non rectangular image?
I want text around maps of different countries to wrap around the country's shape in such a way that the text always keeps the same distance from the country's border even though the border itself isn't straight.
Is this possible?
You can use this method, where you float divs to block off the shape's area.
So - the answer is "Yes - it can be done". But as far as I know there's no "easy" way like a CSS "text-wrap" option.
It looks like that kind of support is on the horizon.
As Dave said, there is CSSTextWrapper, which is probably the best way to do it at the moment, but a relatively recent W3C working draft outlines a method to use more complex shapes using SVGs, and perhaps raster images with outline detection.
How long it will take for it to be implemented in major browsers, let alone finished, is anyone's guess.
At the moment, it can be done, with difficulty. With luck, it will be much easier in the future.
There's a jQuery plugin called Bagon designed to do exactly this.
As others have already said: yes, it's possible... but it's not so difficult.
Customers tend to like this kind or wrapping, at the end I made a script for it: http://www.miguel-svq.com/textwrap.html
This can use floating divs or slice the image, as you prefer.
There's the well-supported shape-outside CSS property. You can even just give it the PNG and it'll figure out the shape from the alpha channel.

I'd like to circle mask the following:

I checked the previous topics but since I am very new to html I couldn't find the answer.
appreciate your helps.
It would depend on how you want to go about it, the simplest and unfortunately the least robust route would be to create a large .png with the alpha in the center transparent.
There are also ways to do it using html5 canvas, CSS3, etc. but I think the more important question is what you are trying to do with it before you decide the route to take. (do you need it to resize, do you need it to change colors, etc.) Here is a link to another stack overflow post that may get you on your way.
Best way to mask an image in HTML5
I'd like to know if anybody knows of a good and preferably quick technique for auto cropping images (i.e. BitmapDatas), similar to how GIMP does it? This basically means cropping an image to remove as much unnecessary background as possible, so that all you have left is a rectangle which contains the actual image.
Have a look at BitmapData's getColorBoundsRect() method which does that for you if you pass the correct arguments.
Also have a look at PlasticSturgeon's excellent article explaining to use the function.
I am trying to create a similar effect as seen here:
http://timothypoon.com/blog/2011/01/19/html5-canvas-particle-animation/
However, I can't seem to get this to work on my page and I would like to apply this effect in a div that contains an image. Is this possible or does everything have to happen on the canvas?
When I try to recreate the effect described in the tutorial I get lots of errors such as variables not being defined etc.
You could re-create this using Canvas, or using CSS transformations and shadows, or a mixture of the two. As for the undefined variables, I can't help as you've not posted your code.
A clean approach would be to do everything within the canvas, using JavaScript. You can draw both the foreground grass, and background mountains to the canvas. However if you want to partly use a <div>, you can overlay the div on top of the canvas using CSS position:fixed or position:absolute, also using CSS z-index to set their order.
I recommend the following link, scroll down for the image drawing:

I don't know how else I can help, as the tutorial that you've provided explains everything quite well. But if you've got any further queries, feel free to comment, or update your question.
You can use the proton particle engine easily achieve the effect you want, Its API is very simple.http://a-jie.github.io/Proton/
The problem I have about using the map & area tag is that I havent been able to find out a solution to having "holes" in the area, for example imagine a lake on map, you dont want that area to be clickable.
Example code:
http://jsfiddle.net/WbKqS/
In this example I have placed 3 lakes on the map but I dont want the lakes to have the hovereffect/being clickable, is this possible? Maybe with another technique?
HTML areas don't support having holes or multiple sets of coords, so you'll need to go with a workaround.
How about a solution based on the approach illustrated below?
I don't think this is a good idea to develope this using area map. I would use Raphael instead. a map example with Raphael
You could position other 'hidden' (div) elements over the lakes, preventing the hover effect from being triggered. Disadvantage is shape of the elements (square). Using canvas could be a solution for that, but not all browsers support it.
I wish it worked that way, but it does not as of right now. Try using SVG format instead. That's Scalable Vector Graphics technology. SVGs support holes and multiple shapes or islands if you will.
Hope this helps, it helped me in Firefox.
If that method fails, I'll look into using <canvas> tag.
I'd like to know if it's possible to reproduce in CSS/HTML the effect you see in this magazine, with an image floated between 2 columns of text and the text wrapping around it:
I know only modern browsers support 2-column layouts, so my questions are:
Can this be done in modern browsers? If so, how? We are essentially doing a "float:both" but ofc that directive doesn't exist....
Is there any backward compatible hack to sort of do it in older browsers?
Finally, if you can do this in HTML/CSS, I would think the image would still have to be square, so that the wrapping effect would not be as organic as it is here. Would it be possible to reproduce the effect exactly, rather than having the image square with whitespace, eg, to the left and right of Ron Paul's head? Would you have to slice up the image to accomplish that?
It's not easily doable (especially for dynamic text). All the techniques have various downsides.
Here's one possible technique for "float center":

For modern browsers, there's a jQuery plugin that can do it precisely:

Here's the tedious, manual version that inspired the above jQuery plugin:
