This time I will show you how to implement the report effect of dynamically displaying color blocks in Html. What are the things to note in Html?What are the practical cases? Let’s take a look. .

Use html color blocks to dynamically display data

<style type="text/css">
            *{
                padding: 0;
                margin: 0;
            }
            .tubiao,.jihua,.shiji,.riqi{
                width: 100%;
                overflow: hidden;
                margin-top: 10px;
            }
            .left{
                width: 10%;
                float: left;
                text-align: center;
                height: 25px;
                line-height: 25px;
            }
            .right{
                width: 90%;
                float: right;
                height: 25px;
            }
            span {
                width: 5%;
                height: 100%;
                text-align: center;
                display: inline-block;
            }
