- Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user moves the mouse out of the image, the image is changed to another one and one more 'sun' emoji is displayed under the image. When the number of 'suns' reaches seven (7), all 'suns are deleted (reset) and start to be displayed again. For example, the 8th time user moves the mouse out of the image, one 'sun' is shown, the 9th time - two 'suns', and so on. Note: - You should use two images. Each time the user moves the mouse out of the image, the image is changing. If an image of "Winter" is displayed it will change to "Summer", and opposite, if an image of "Summer" is displayed it will change to "Winter". The special character code for the 'sun' is "☀".
