jQuery .show() adds style="display:inline-block" to elements

Question

I'm working on a site I inherited at work that shows donation progress using progress bars / labels. The majority of the lists will have 9 years in the (e.g. 1990-1999) but the last one has 13 (2000-2012). Because of this, I have a javascript function showHiddenBars() which shows / hides the respective elements.

On first load, everything displays correctly (2000-2012 is displayed by default) but after hiding them and then showing them, it messes up the layout. From what I can tell via Google Chrome's inspector is that when the .show() function is used it is adding style="display: inline-block" to my span element which houses the label. I am using the clip easing effect of jQuery UI with the show and hide functions.

How do I prevent .show from adding style="display: inline-block;"

The javascript:

function showHiddenBars() {
    "use strict";
    //show the bars we aren't using.
    $('#decade10').show("clip");
    $('#decade11').show("clip");
    $('#decade12').show("clip");
    $('#decade13').show("clip");
    $('#decade10label').show("clip");
    $('#decade11label').show("clip");
    $('#decade12label').show("clip");
    $('#decade13label').show("clip");
    $('#decade10AmountGiven').show("clip");
    $('#decade11AmountGiven').show("clip");
    $('#decade12AmountGiven').show("clip");
   $('#decade13AmountGiven').show("clip");
}
function hideHiddenBars() {
   "use strict";
    //hide the bars we aren't using.
    $('#decade10').hide("clip");
    $('#decade11').hide("clip");
    $('#decade12').hide("clip");
    $('#decade13').hide("clip");
    $('#decade10label').hide("clip");
    $('#decade11label').hide("clip");
    $('#decade12label').hide("clip");
    $('#decade13label').hide("clip");
    $('#decade10AmountGiven').hide("clip");
    $('#decade11AmountGiven').hide("clip");
    $('#decade12AmountGiven').hide("clip");
    $('#decade13AmountGiven').hide("clip");
}

The HTML:

Answer 1

Explicitly set the style for the visibility the way you want it: don't rely on hide() and show():

element.css('display', 'none'); equivalent of hide()
element.css('display', 'inline-block'); equivalent of show()
element.css('display', 'block'); What you want

Answer 2

I think if the defaut style for the element is inline then it will add inline-block, at least for select dropdowns it also adds inline-block. If you need to add block then use the .css

$('#el').css('display','block');

You can still use .hide() to hide, that does not need to change
