The Fiddle

Answer 1

One simple error:

-webkit-transition: all, 0.2s, ease-in;
-moz-transition: all, 0.2s, ease-in;
-o-transition: all, 0.2s, ease-in;
transition: all, 0.2s, ease-in;

Change to:

-webkit-transition: all 0.2s ease-in;
-moz-transition: all 0.2s ease-in;
-o-transition: all 0.2s ease-in;
transition: all 0.2s ease-in;

Transition values are not comma separated. They are a single declaration. If you want to declare multiple transitions, THEN you comma separate them.

See W3C Docs or/and CSS3.info

Value: <single-transition> [ ‘,’ <single-transition> ]*

Where <single-transition> is:

<single-transition> = <transition-property> <transition-duration> <transition-timing-function> <transition-delay>

So, a comma separated example would be:

transition: opacity 0.5s ease-in, width 1.5s ease-out;
/* 0.5s for an opacity transform while 1.5s for a width transform */

Answer 2

Improper declaration of transition:

 -webkit-transition: all 0.2s ease-in;  /* Chrome 1-25, Safari 3.2+ */
 -moz-transition: all 0.2s ease-in;  /* Firefox 4-15 */
 -o-transition: all 0.2s ease-in;  /* Opera 10.50–12.00 */
 transition: all 0.2s ease-in;  /* Chrome 26, Firefox 16+, IE 10+, Opera 12.10+ */
