Modal Forms not working from JS

Before the question, I have just extended support and I bought two licenses, just wondering why I do not have access to other questions?

Well, first problem I have is modal form. I need to create simple alerts which are not shown by a click, than by code. I have copied simple modal window at the end of the code:

	
		
			
				Modal Heading
				×
			
			
				
					

				
				
					OK
				
			
		
	

and when I need to display it from js i run the code:

static simpleAlert(cBody){
	$("#aleeeertMsg").text(cBody);
	$.magnificPopup.open({
		items:{src: "#aleeeert"},
		mainClass: 'mfp-no-margins mfp-fade',
		type: 'inline',
		closeBtnInside: true,
		fixedContentPos: true,
		removalDelay: 500
	}, 0);
}

only transparent black screen shows, and window is hidden somewhere in the back...

Second, portfolio masonry images not displaying correctly in tabbed div. they re-arrange when window is resized but not initially. Also, tab where are they displayed is initially hidden (not the first one tab)
