JavaScript Syntax Is Needed to Create Excellent Visual Effects

It is not unusual for certain types of visually involved websites to cause events to dynamically transpire based on whether the viewer's cursor is crossing over a certain piece of text or an image. A common feature is to have an element visually appear at the position of the cursor as it overlaps with a piece of content and to have it disappear once the cursor is no longer hovering it; this is commonly used to display an informational tooltip for the user's benefit. The tooltip can be a small piece of text enclosed in a box, but it can also be a visually elaborate image that features a lot of relevant text content. In either case, coding this sort of effect is possible by merely using HTML and CSS, but if only these two languages are used, the pop-up will stay still at the X- and Y-coordinates where the cursor first started to overlap with the triggering element.
To get a tooltip-like pop-up to dynamically follow the position of the user's mouse cursor as it is moved, a small file containing JavaScript syntax will have to be created and called by one of the other two files. This effect tends to look more professional in the eyes of viewers browsing websites for information. However, the JavaScript syntax should be expanded so that the pop-up will spontaneously shift its position as soon as the cursor "carrying" the pop-up moves far enough to the edge of the browser's window that part of the pop-up's content would become obscured.
The JavaScript syntax that can be used to make a pop-up automatically shift to account for a lack of remaining window space involves measuring the X- and Y-coordinates of the cursor, comparing them to the size of the window as a whole, and comparing the distance between these coordinates and the window's edges to the dimensions of the tooltip itself. While web programmers would find this syntax to be easy to visualize, various JavaScript libraries are available that provide neatly compiled forms of this functionality for a wider range of web owners.
