I have web application which can upload images to server.
I want to crop and rotate image before sent to server.
Any way to do this using HTML 5 Canvas
Yes, html canvas can crop and rotate an image.
Crop: Use the extended properties of context.drawImage.
context.drawImage(img,cropX,cropY,cropWidth,cropHeight,0,0,cropWidth,cropHeight);
Rotate: Use the context.rotate property.
// set the point of rotation (example below sets rotation point at center-image)
context.translate(img.width/2,img.height/2);
// do the rotation (in radians)
context.rotate(radianAngle);
Note: all transforms (translate,rotate,etc) are cumulative unless you context.save/context.restore.

How do I recreate this mock-up using CSS? Its easy to create this using a layer mask in Photoshop but how do I recreate it using CSS?
It needs to be responsive so I'd rather code it than upload the image.

A bezier curve svg clip path is likely what you need, with two divs one with a higher z-index than the other. This illustrates the technique, drawing your bezier curve might be best done in a graphics tool.

You'll overlay a div with the clip path over the top, then set an opacity to it and a colour so it shines through.

Is there a way to draw a sprite with no rect and only a width height and colour like pygame.draw.sprite(colour,width,height)
The answer Is in these docs here https://www.pygame.org/docs/ref/draw.html you can but it requires some shape such as a circle, line, rectangle like you said, or even other shapes.

Say for example, I have a div with a dynamic image which is stored in amazon web server, and i have such div multiple times in my website. What want to do is to click the image to enlarge the image. How should i proceed?
I have created a model which works when pressed on the image but the images are not dynamic.
I have the image link in amazon server
Expected: Something like in some websites image enlarges on click. And the images should be dynamic. Not static image
Once there was a plugin/library called Lightbox. I wonder, if it is still around, but that should do the trick.

I am trying to find the best way to create a shape in Access that is semi-transparent. I am not sure if this is possible but i would like to have a rectangle which is semi-transparent so i can use it to cover certain objects so the user can see the object but with an opaque visual type effect. Is there some code that can help do this?
Ms Access does not currently support transparency

How do I make a curved beam of light with svg / html5?
It should look like this (the orange and blue lines):
Hopefully this can be done with snap.svg or d3.js
A glowy/colored path can be a challange. Basically you can create a gradient stroke which is not native to SVG. However D3 has addressed this see:
