采用flex布局實現home主頁的搜索左邊是圖片，右邊是文字

（1）先放代碼，即：

我認為flex是設置一段區域，然后flex=1的部分會自動使用剩下的所有空間。

（2）父元素title-2設置為：

　　　　display: flex

　　　　height: 9rem

（3）同時，設置圖片的高度為8.8rem，然后再用padding使用余下的高度，即：

　　　　height: 8.8

　　　　rem width: 8.8

　　　　rem padding: .1rem

（4）然后將文字和按鈕用一個div包裹起來，然后它的flex為1，讓它使用父元素剩下的空間；然后<p>和<button>是塊元素，所以會一行一行的顯示；

效果為：
