我在输入字段上添加了一个css焦点.它具有包含边框和阴影的默认样式.当我专注于输入字段时,下面的输入字段会略微向下移动.我尝试为li增加一个高度,但这不起作用.
/* CSS
input[type="text"],
input[type="password"] {
border: 1px solid #CCCCCC;
box-shadow: 0 -1px 3px rgba(0, 0, 0, 0.2);
min-height: 22px;
padding: 3px;
}
.checkout input:focus {
border:3px solid #6b991c;
padding:2px;
}

拥有一个之前没有的边框(或增加border-width)将有效地使元素变大,因此可能会导致其他元素移动。为避免这种情况,您应该尝试确保总大小(高度或宽度 + 填充 + 边框 + 边距)相同。在您的情况下,我认为您应该尝试向未聚焦的样式添加 2px 边距以进行补偿(因为聚焦元素的边框大 2px)。尝试:
input[type="text"],
input[type="password"] {
border: 1px solid #CCCCCC;
box-shadow: 0 -1px 3px rgba(0, 0, 0, 0.2);
min-height: 22px;
padding: 3px;
margin: 2px;
}
.checkout input:focus {
border:3px solid #6b991c;
padding:2px;
margin: 0;
}

尝试这个:
.checkout input:focus {
margin-right: 50px;
padding: 2px;
margin: -1px;
}

因为您在边框上添加了3px,在未聚焦状态上添加了2px的填充,所以您必须对聚焦状态进行一些数学运算,以使其等于未聚焦状态。在您的情况下,在聚焦状态下在空白处加上-1px应该会取消跳转。
