边框和溢出导致问题

时间:2016-12-12 09:06:12

标签: html css overflow viewport hidden

如果我可以要求你swing by Codepen:并且全屏查看(媒体查询没有完成),你会发现我在解决布局问题时没有使用overflow:hidden。

你会看到

a)Some行和图标会进入绿色部分 b)尽管有边框标记,蓝色部分仍然低于其他两个部分

如果我启用overflow:hidden全局隐藏,则布局显示我想要的方式。但是它有很多不必要的效果,阻碍了汉堡导航菜单的使用。

问题

A)尽管使用float和viewport设置为33.33vw,为什么这三个部分都没有对齐?我认为这是关键问题。

尝试将以下CSS添加到您已有的

header {width: 100vw}
.somebar {
    float: right;
}   
header ~ a {
    float: left;
    width: 33.333%;
}

答案 1 :(得分:0)

我建议使用flexbox而不是float。通过媒体查询,您还可以节省大量时间和精力 将三个div包装在容器中并将其设置为

.container {display: flex;}

然后将三个孩子的宽度设置为33.33%,它们将彼此相邻排列并填满整个屏幕。随着屏幕的增大或缩小,它们也会自动调整。

CSS Tricks是flexbox的绝佳资源。

作为旁注,我建议尽可能将代码保持为DRY(不要重复自己)。如果您编写CSS以在特定大小的屏幕上工作,则只需使用@media来更改需要更改的内容。例如,您只需设置一次颜色,因为它们保持不变,无论屏幕大小如何。
