Please note: If you are using the scroll wheel to scroll a page or are using other special function buttons on your mouse but are not actively clicking or moving anything on the screen using the mouse pointer arrow, then we still consider your mouse pointer to be at rest and want to know where on the screen it is resting (on average).Īlso note: We are mostly interested in answers based on using the standard released version of Ubuntu (not beta versions, highly customized desktops or other OS). We might expand upon this poll later on to get more correlation data. Please take a few minutes to observe where your mouse pointer tends to fall to rest, while you are doing your most common computer activities (websurfing/reading/writing/etc). We are also interested in knowing what type of pointing device you are using (to see if there is a difference): R) Pointer tends to rest on the right side of the screen. L) Pointer tends to rest on the left side of the screen.Ĭ) Pointer tends to rest in the center of the screen. M) Pointer tends to rest near the menu of the active window. The main variables we want to measure are: The purpose of his poll is to gather data about where on the screen the mouse pointer rests when it is not doing anything productive on the screen (not clicking buttons, dragging scrollbars, etc).
Mark Shuttleworth is wants us to collect research data about people's mouse usage. So I simply added pointer-events: none to my. Pointer events are anything that has to do you your mouse, such as clicking, scrolling, or moving your mouse over (hover) an element. I suddenly remembered that CSS has a property called pointer-events which allows you to decide whether or not an element should react to pointer events. This is unacceptable! Pointer events to the rescue! The text elements are still grayed out by the overlay. This time we just changed the stacking order directly with CSS. Unfortunately, doing this will result in the the exact same thing as before when we physically moved the element below the element. Now card-overlay will be put in front of card-info (which still has z-index: 0) because it has a higher stack order ( z-index: 1) and now the color change on hover event will again work uninterrupted - which is great, but. Let’s not use that approach, and move the element back to its original position. We solved a problem while creating another.
Now that the stacking order has been switched around, the text elements get grayed out by the overlay, which is now in front/on top of it. Great, now the overlay transition is no longer interrupted when you move your mouse over the text area (try it).īut wait. In this case, the container that contains the name and role text elements comes after the card-overlay element: The one that comes last in your HTML wins. So since we have two elements that are both absolute positioned and they both have a default z-index of auto (0) which of them is in front of the other in the stacking order (one has to win)? The default z-index value of all elements on a web page is auto, which is the same as zero 0. The element that has the highest z-index value (number) is put in front of other elements - assuming their position value is the same. However, there is a default stacking order that occurs, if you don’t address it directly with CSS first. The stacking order is usually controlled by the CSS z-index property. So why does the hover event get canceled when you move your mouse over the text area?īecause of the stacking order of the HTML.
