<style> .left{ width: 7px; height: 7px; border-top: 2px solid #ff0000; border-right: 2px solid #ff0000; transform: rotate(-135deg); } .right{ width: 7px; height: 7px; border-top: 2px solid #ff0000; border-right: 2px solid #ff0000; transform: rotate(45deg); } .top{ width: 7px; height: 7px; border-top: 2px solid #ff0000; border-right: 2px solid #ff0000; transform: rotate(-45deg); } .bottom{ width: 7px; height: 7px; border-top: 2px solid #ff0000; border-right: 2px solid #ff0000; transform: rotate(135deg); } </style> </head> <body> <div class="left"></div> <hr> <div class="right"></div> <hr> <div class="top"></div> <hr> <div class="bottom"></div> </body>
