SLIDERSliders are used to change data over a range by moving pointer between maximum and minimum value. This is also used as range selector to input data to any process.
Click on the above slider
The pointer can be moved by using Mouse pointer ( Holding the left mouse button ) or by using left and right arrow of keyboard.
These are used in color picker, volume controllers etc. We have to link Jquery UI from google CDN like this.
OPTIONSWe can add various options to manage our slider as per requirement.
Double pointed slider with Minimum and Maximum rangeBy using rage option we can display two pointers to same slider to show Min and Max value . It works like range selector giving two outputs. Instead of reading one value we will get two values.

Event: Start and Stop of movementStart and stop event is triggered by starting and stopping of pointer while moving or changing position.
Changing value through text boxWe can change the value by entering data in a textbox or by sliding the pointer.
By using another widgets know as spinner we can increment or decrement data in a text box. We will try to develop a script to interlink one Spinner with Slider so by changing any one, other value can be changed.
