The bullet box we talk about every day is a very general concept. All dialog boxes, floating layers, and prompt bars are habitually called bullet boxes. In fact, we can divide bullet boxes into two types: modal bullet boxes and non-modal bullet boxes.
The biggest difference between a modal popup and a non-modal popup is whether to force user interaction. The modal popup will interrupt the user's current operation process. If the user does not operate on the popup, the rest of the functions cannot be used. From this aspect, we can see that the advantages and disadvantages of the modal pop-up box are very obvious: the advantage is that the user's visual focus can be obtained well, and the disadvantage is that it interrupts the user's current operation process. The modal pop-up box is a kind of heavy feedback, which is generally used for users to perform b2b data important operations. Common modal popup types are dialog (Dialog/Alter) , action bar (Actionbar/Actionsheet/ActionView) and floating layer (Popover/Popup) . Because many components of iOS and Android are now common, I will only introduce one component that is too similar in the following article.
A dialog box is generally used for a user to perform a very important or risky operation. At this time, a dialog box will pop up to prompt the user with information, and the user can make judgments according to the prompt. Generally, it will appear in the middle of the screen, which will block the main content of the interface.
At present, there are many design styles of dialog boxes, users can input information, and can also be used for marketing promotion.
