Twitter Bootstrap hide css class and jQuery

I'm using the hide css class to hide a button on page load. The problem is that when i try to show the button i've previuosly hidden with jQuery the button is smaller. (the same thing doesn't happen when i use jQuery to hide and then show the button) Thanks for helping. Edit: hide class is just this: ``` .hide { display: none; } ``` My button: ``` <a class="btn hide" id="buttonEditComment" href="javascript:void()"><i class="icon-comment"></i> Edit comment</a> ``` Javascript i use to show the button: ``` $("#buttonEditComment").toggle(); ```
