What I have :
We had set up a SharePoint online site for a customer. So, we developed a custom master page and some custom styles.
But we never touched the calendar page, nor the task list.
So, they are standard.
What is the problem :
So, as you can see, every item is offbeat to the right and there are two scrollbars.
I've tested it on IE 11, FF 47.0 and Chrome 51.0 and the problem only appears on IE 11.
What I searched :
When I look on the F12 console, there are inline style set to every item. and that is on that inline styles that the left position is fixed. I'll attach you this console image :
What I would like to find :
So, to avoid this, I need to know where is hidden the code that generates the calendar view.
Do you have any idea ?
