What is SVG?
- SVG is stands for the Scalar Vector Graphics.
- It is XML based vector image format.
- It is used in 2-D graphics.
- It supports interactivity and animation.
- Its specification is open standard which is developed by the W3C since 1999.
- Since is XML based, so they can be edited using any text editor.
- They can be edited, indexed, searched, scripted etc.
- They can be zoomed and scaled easily.
- They do not loose quality when zoomed or resized.
Popularly used image formats are jpg, jpeg and png. But they are all based on bitmap. Though Bitmap is used oftenly for transparent backgrounds and when a lot of colors are there in an element. But has a major drawback. Since, they are of fixed size. So, when the picture is zoomed or compressed it either pixelate or the image becomes blurry.
But, it is very handy in this case since it is vector based.
How SVG helps HTML5 and CSS3 developers?

- CSS selectors target these elements such as paths, eclipse, rectangle, circles etc.
- When CSS and SVG are combined, we can eliminate the whole image.
- We can do masking (mask) i.e. to alter the visibility of parts of an image.
- Clipping (clip-path) can be performed where a segment of an element is removed so that a standard regular image can be transformed t any shape.
Graphical effects can be given using filters (filter) such as blur, brighten, shadows
Here, we see that how SVG can be using in different sizes without loosing of data which we are either compressing the image or zooming it on any browsers. This helps the web developers to use same element in different sizes.
