i think you made some spelling mistakes, not sure tho also dont put spaces between "="我想你犯了一些拼写错误，不确定也不要在“=”之间加空格

<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>BackGround</title>
    </head>
        <body>
            <button id="red"> R </button>
            <button id="blue"> B </button>
            <button id="green"> G </button>
            <script>
                let body = document.querySelector('body');
                document.querySelector('#red').onclick = function(){
                 body.style.backgroundColor = 'red';
                };
                document.querySelector('#blue').onclick = function(){
                    body.style.backgroundColor = 'blue';
                };
                document.querySelector('#green').onclick = function(){
                    body.style.backgroundColor = 'green';
                };
                </script>
            </body>
</html>
