It seems that generally a css clip-path is used to hide beginning at the edges of an element. I can use something like this:
clip-path:circle(70% at center);
and get something like this:
Is there a way I can invert that? I want my result to be something like this:
I want to clip the center of the image, not the edges. It's an SVG, so I tried something like this pen, animating a radial gradient: http://codepen.io/ethanclevenger91/pen/myMYwQ
But that didn't work like expected. There's the animated one and then one with what I assume the final step of the animation cycle should look like, but it doesn't. Any light on either of these would be appreciated.
You can use a still use a clipPath if you use it in its url form i.e. as svg markup. Draw the path outer rectangle clockwise and the inner ellipse (using two or more elliptical arcs) anticlockwise, drawing everything as a single path together with clip-rule="evenodd"
Alternatively you could use a <mask>. This is a simpler, but slower solution. Draw a white ellipse within the mask area and that part of the mask will be opaque.
So here's what ended up happening:
Since the background I was trying to match was a solid color, I gave the circles a stroke double their radius (since stroke is applied centered on the edge of the object) and then applied a clip-path the size of the object. Then I animated the stroke to 0. Will update with a link to the application when it's live.

I have a handwritten signature to animate as if it is beeing written. I draw it into Illustrator as a path, but with the variable width tool I gave it a nice shape to look like it made by pen. I generated the svg code, but it made me a filled element with strokes, so I can only animate the stroke.
Is there a way to animate just the fill, or I can only animate stroke with equal width.
Or can I save svg some other way?
i am trying to create the following image using css.... so far i've got this after googling a bit http://jsfiddle.net/w9Zgc/ and i want to make the following shape..
is there any way this can be done... any help would be appreciated.. oh and i would like the shadow to be like the one here... http://jsfiddle.net/w9Zgc/
So I managed to create an icon that renders more or less the same in all current browsers. I had to use an extra useless span, unfortunately.

The triangle is made of two parts:
the upper (triangular) part is a transformed (skewed and rotated) square with rounded corners.
the bottom of the triangle is the bottom part of a rectangle with rounded corners.
Both parts are cut and joint at certain places to form the triangular shape with rounded corners and shadows.
What is the HTML CSS solution for highlighting specific areas of a map/floor plan like this?
http://www.centrecourtshopping.co.uk/store-info/
They use sprite image look here.
Basically, it works like that:
The map with dark-blue regions is completely static.
There is invisible layer on top of it made from small rectangular in their case <a> -- each corresponds to single dark-blue region and posses its its own id.
When cursor is placed over a rectangular with id x the sprite image is nicely aligned with its background (by setting CSS's background-position).
Do not think, this magic would be possible without using JavaScript.
I'm trying to create a "door opening" 3D effect in CSS but I just can't do it. The problem is that using rotateY() function makes the element spin. You can check it here http://jsfiddle.net/uC4du/1/
Do you know how to change the rotateY "reference axis"? What should I do to make the element rotate using its left corners as reference?
You can use 'transform-origin' property ( http://www.w3schools.com/cssref/css3_pr_transform-origin.asp ).
Set it to something like: "-webkit-transform-origin: 0% 50%;"
Here is your example using that property: http://jsfiddle.net/aV76H/
Hope it helps!
I have a problem on roating an Image on a canvas in gdi+, I am using the following code, however I find there are alias on the edge.
myPathMatrix.Rotate(GetDCAngle(), MatrixOrderAppend);
myPathMatrix.Translate(
GetDCX(),
GetDCY(),
MatrixOrderAppend);
canvas->SetTransform(&myPathMatrix);
canvas->Draw(XXX);
I used the following code to remove the alias, but failed.
canvas->SetInterpolationMode(InterpolationMode::InterpolationModeHighQualityBicubic);
canvas->SetSmoothingMode(SmoothingModeAntiAlias);
How can I remove the alias at rotated image's edges.
Many thanks!
It's been a while since I worked with GDI+, but I'd assume there's no effective option to remove antialiasing around the edges when rotating. The reason is basically that pixels are square. To rotate an image an amount other than a multiple of 90 degrees, you need to use some kind of interpolation to estimate pixel colours where there weren't really pixels before.
So if there's nothing in the library to specifically take away antialiasing around the edges, have you thought about drawing hard lines in the background colour along the borders? It should be easier to draw those lines without any antialiasing.
