What is the canvas element in HTML5?
Article Introduction：The HTML5 element is a blank canvas for drawing graphics using JavaScript on a web page. It does not display anything by itself and must draw shapes, text, images and animations through scripts. To use, first add a tag with id, width and height in HTML; then get the element through document.getElementById() and call .getContext('2d') to get the drawing context; then draw the content using the context method. It can be used to draw shapes, render text, display images, create animations, and build games. It should be noted that canvas is based on pixels, lacks built-in event processing and barrier-free support, and performance is also affected by complexity.
