How to get the mouse position in JavaScript?
Article Introduction：In web development, there are three main methods for JavaScript to obtain mouse position: 1. Use clientX and clientY to obtain the browser's visual area coordinates, which are suitable for following the cursor or judging areas; 2. Use pageX and pageY to obtain the entire page coordinates including the scrolling part, which is suitable for scenes where absolute positions are required; 3. Use offsetX and offsetY to obtain the relative position of the mouse inside the element, which is often used for canvas or hot zone detection. In addition, after obtaining the mouse coordinates, it can be used to customize the interactive functions such as cursor, drag and drop sorting, drawing tools, hover judgment and game control. Selecting the appropriate coordinate system and debugging multiple values ??can avoid confusion.

How to handle mouse events on a canvas?
Article Introduction：To handle mouse events on canvas, you need to manually monitor and judge the trigger area in combination with coordinates. 1. When obtaining the mouse position, you need to convert clientX and clientY to the internal coordinates of canvas. The formula is x=e.clientX-rect.left, y=e.clientY-rect.top; 2. If there is a zoom or transform style, the coordinates need to be adjusted accordingly; 3. To determine whether to click on the graphic, you need to record the graphics information in advance and detect whether the coordinates fall in the corresponding area when clicking; 4. To achieve the hover effect, you can listen to mousemove and clear and repaint canvas or use double buffering technology; 5. Note that the mobile terminal needs to use touch events to replace hove

Creating tooltips with pure CSS
Article Introduction：The method of implementing tooltip with pure CSS is: 1. Use nested HTML structure to wrap the trigger area and prompt content; 2. Control the display and hide of child elements through:hover; 3. Use absolute positioning to set the prompt box position; 4. Add animation to improve the experience; 5. Pay attention to z-index and multi-directional adaptation. The specific implementation includes setting .tooltip as relative positioning, .tooltiptext is hidden by default, becomes visible when hover, and can add transition to achieve fading and delay effects. At the same time, positioning in different directions is controlled through class names, but it should be noted that the effect of hover on the mobile side may be limited.
