Answer 1

I think that using the CSS's focus property should work:

input:focus {
    border: 1px solid #006600;
}

Edit: DEMO [JSFIDDLE]

Update: To remove the default outline (which is yellow), you can set the outline property to none:

input {
   outline:none;
}

Here is the updated fiddle.

Just add the following lines of code to your CSS and this should fix your problem:

input[type=text], /*transition delay*/
textarea {
 -webkit-transition: all 0.35s ease-in-out;
 -moz-transition: all 0.35s ease-in-out;
 -ms-transition: all 0.35s ease-in-out;
 -o-transition: all 0.35s ease-in-out;
 outline: none;
 padding: 3px 0px 3px 3px;
 margin: 5px 1px 3px 0px;
 border: 2px solid #f1f1f1;
}

input[type=text]:focus, /*creates highlight effect*/
textarea:focus {
  box-shadow: 0 0 3px rgba(81, 203, 238, 1);
  padding: 3px 0px 3px 3px;
  margin: 5px 1px 3px 0px;
  border: 1px solid rgba(81, 203, 238, 1);
}

input[type=password], textarea{ /*prevents showing outline border when clicked*/
 outline: 0;
}
