Materializecss导航栏徽标图像位置

Question

我在放置自定义图像徽标时遇到问题，我希望将其完美地放置在导航栏中，但是在移动视图和桌面视图中却有些偏离。 Mobile view

我尝试使用vertical-align: middle;的台式机版本也有点过时，但是它不能正常工作。

示例：

.logo {
    display: inline-block;
    height: 100%;
}

.logo>img {
    vertical-align: middle;
		position: relative; 
    top:1px; 
}

Answer 1

vertical-align: middle仅适用于带有display: table-cell的元素。但是，还有一些更好的方法。

尝试结合使用绝对定位和垂直居中对齐：

.logo {
    display: inline-block;
    height: 100%;
}

.logo>img {
    position: absolute;
    top: 50%;
    transform: translateY(-50%);
}
