一、3D筛子

在这里插入图片描述

1.HTML

<!--ring div starts here-->
<div class="ring"><i style="--clr:#00ff0a;"></i><i style="--clr:#ff0057;"></i><i style="--clr:#fffd44;"></i><div class="login"><h2>Login</h2><div class="inputBx"><input type="text" placeholder="Username"></div><div class="inputBx"><input type="password" placeholder="Password"></div><div class="inputBx"><input type="submit" value="Sign in"></div><div class="links"><a href="#">Forget Password</a><a href="#">Signup</a></div></div>
</div>
<!--ring div ends here-->

2.CSS
