我想在一行中显示两个相同大小的部分，当浏览器屏幕变窄时，第三部分应该占据下一整行，但它没有正确对齐，请有人帮助我，检查我的代码，代码中的问题在哪里

使用合适的bootstrap classes属性。
p {
border: 1px solid black;
background-color: #A52A2A;

margin-right: auto;
margin-left: auto;
font-family: Helvetica;

border: 1px solid rgb(0, 128, 0);
float: left;
padding: 0 15px;
}
请将width属性从class: "。p" 或指定'100%'宽度
