I m unable to understand why font sizer 'icons' do not show with text in article view.

please guide ?

Hi. Check your template's CSS code, the issue is probably there.

which css code ?

some hint please !

Hey, i cannot know what is going on in your template. You should know better. In any case ensure that you have not disabled those buttons through K2 settings.

As you know there is no option to disable the buttons separately from the text 'font size".

One thing i forgot to mention that the buttons are there, and when i click on that space, the text resizes. The problem is the visibility of buttons as they do not show. The same is the case with rating stars.

any solution ?

Since they are there and they do not display it's clearly a matter of your template's CSS code. Please revise the code, or have a developer do it for you in case you are not familiar with CSS. A great tool for debugging CSS under Firefox is Firebug. You can get it at getfirebug.com
