Answer 1

You can do that with just CSS3 transition . Check below update.

 * { margin: 0px; padding: 0px; } img { cursor: pointer; position: relative; margin: -65px; /* Adjust this value to expose the image */ left: 0; transition: left .5s; } img:hover { left: 65px; /* Use same value as used as negative margin */ } 

 <img id="myImage" src="https://lh4.googleusercontent.com/proxy/LxuD_Ceq6NrRGBW2mF_6Cy9zeO_vqkV8ZTRMdzjc_LxE0InnXBLp1_BkWuyhlg0EMJPt-Njzzp5_4cuR562m6dh8QNTW_1kzsf9pXcXiKI2ZK6wEMJH2TAAiQqpQUewNMKI=s0-d" />
