重點:
1.當input框foucus時,border顏色改變,而不是保留outline
2.button按鈕預設box-sizing: border-box
.container {
width: 500px;
height: 50px;
margin: 100px auto;
}
.parent {
width: 100%;
height: 42px;
top: 4px;
position: relative;
}
.parent>input:first-of-type {
/*輸入框高度設定為40px, border佔據2px,總高度為42px*/
width: 380px;
height: 40px;
border: 1px solid #ccc;
font-size: 16px;
outline: none;
}
.parent>input:first-of-type:focus {
border: 1px solid #317ef3;
padding-left: 10px;
}
.parent>input:last-of-type {
/*button按鈕border並不佔據外圍大小,設定高度42px*/
width: 100px;
height: 44px;
position: absolute;
background: #317ef3;
border: 1px solid #317ef3;
color: #fff;
font-size: 16px;

}
