Use 'auto' instead of 'initial' in CSS

'initial' is not supported by all browsers (including all versions of
Internet Explorer and Opera 12 [1]), which causes visual glitches [2].

As the initial value for 'left' is 'auto' [3], this should cause no
visual changes in the browsers that supported the previous version.
