即使 html 和 body 是 Container Fluid，高度也不是 100% [英] Height not 100% on Container Fluid even though html and body are
问题描述
我有以下布局(我使用的是 Meteor):
<div class="container-fluid fill-height">{{>标题}}{{>UI.contentBlock}}{{>页脚}}<模板名称=家">{{#页眉页脚}}<div class="row body-film"><div id="newsfeed" class="col-sm-offset-7 col-sm-5 block-film">{{#每个故事}}<div class="story">...</div>{{/每个}}
{{/页眉页脚}}
和这个(相关的)css 支持它:
html {高度:100%；}身体 {最小高度:100%}.填充高度{高度:100%；}html 和 body 元素都按预期运行.它们以任何缩放级别或大小填充其区域.
然而，添加了 fill-height 类的 container-fluid 并没有完成这项工作.它只是包装它的内容，而不是填充到底部.这是一个问题，因为它负责将 body-film 和 block-film 添加到页面，它们只是半透明的背景，使整个事物具有某种颜色统一.
这里是一些截图，所有页面都缩小了，所以内容没有填满高度:
现在是选择了 body 元素.如您所见，它很好地填充了父级.
但是 container-fluid 没有.
使用 fill-height 我试过 height 和 min-height，它们看起来完全一样.
感谢您的帮助！
更新
我一直在对这三个元素尝试 min-height 和 height 的所有可能组合，但没有任何效果.
height 当内容对于视口来说太小时，这三个都有效，但是当内容对于视口来说太大时，内容块会溢出body 完全，这意味着电影太短了.
min-height 在我看来是最合乎逻辑的方式，但是当内容太小时会中断.在这种情况下，body 元素不会拉伸以填充其 html 父元素.
这是怎么回事！！！！??????这是 Meteor 使用的新 和
换句话说，如果您希望 div 的高度或最小高度为 100%，那么它的所有父元素都需要定义为 100% 的高度，一直到 html 标签.
您可能需要做的是这样的:
html, body {高度:100%；}.container-fluid {高度:100%；溢出-y:隐藏；/* 不显示超出我身高的内容 */}.body-film {最小高度:100%；溢出-y:滚动；}这可能不是确定的答案，因为这取决于您究竟想要什么，但希望这能让您走上正轨.
I have the following layout (I'm using Meteor):
<template name="headerFooter">
<div class="container-fluid fill-height">
{{> header}}
{{> UI.contentBlock}}
{{> footer}}
</div>
</template>
<template name="home">
{{#headerFooter}}
<div class="row body-film">
<div id="newsfeed" class="col-sm-offset-7 col-sm-5 block-film">
{{#each stories}}
<div class="story">...</div>
{{/each}}
</div>
</div>
{{/headerFooter}}
</template>
and this (relevant) css backing it up:
html {
height: 100%;
}
body {
min-height: 100%
}
.fill-height {
height: 100%;
}
The html and body elements are both behaving as expected. They fill their areas at any zoom level or size.
However, the container-fluid with the fill-height class added isn't doing the job. It's only wrapping it's content, and not filling to the bottom. This is a problem because it is responsible for adding body-film and block-film to the page, which are just semi-transparent backgrounds to give the whole thing some color unity.
Here are some screenshots, all with the page zoomed out so the content doesn't fill the height:
Now here it is with the body element selected. As you can see it fills the parent just fine.
But the container-fluid doesn't.
With fill-height I've tried both height and min-height, and they look exactly the same.
Your help is appreciated!
Update
I've been trying every possible combination of min-height and height on these three elements, and nothing works properly.
height on all three works when the content is too small for the viewport, but when the content is too large for the viewport, the content block overflows out of the body entirely, which means the films are too short for it.
min-height on all three seems to me to be the most logical way to go, but it breaks when the content is too small. In this case, the body element doesn't stretch to fill its html parent.
What's going on!!!!????? Is this a bug in the new Blaze templating engine Meteor uses?
Update
I've just tried height: inherit in my fill-height, and it didn't work either. I'm really at the end of my rope. This seems like it should be so simple.
Update
Alright, I've got a slight change to happen. With this less:
.fill-height {
min-height: 100%;
height:auto !important;
height: 100%;
}
.body-film {
.fill-height();
}
.block-film {
.fill-height();
}
The container-fluid is now full height, but not the body-film and block-film which are using the exact same mixin!!
Here is a screenshot, showing the row.body-film, which should be full height, since the container-fluid above it is (take my word for it, the container-fluid is now stretched to fill the body).
Note, manually adding the fill-height to the html declaration of the row didn't change anything, it behaves identically as if it were simply receiving that through the body-film mixin.
Why is it that some elements don't respond at all to all of these min-height demands?
P.S., I'm using Chrome, but it is on a ubuntu machine, so I can't be sure if there are any inconsistencies.
Answer
The following ended up working:
html, body {
height: 100%;
}
.container-fluid {
height: 100%;
overflow-y: hidden; /* don't show content that exceeds my height */
}
.body-film {
height: 100%;
overflow-y: auto; // a value of 'scroll' will force scrollbars, even if they aren't necessary. This is cleaner.
background-color: fadeout(@studio-bar-color, @studio-body-film-trans-delta);
}
.block-film {
min-height: 100%;
overflow-y: hidden; /* don't show content that exceeds my height */
background-color: fadeout(@studio-bar-color, @studio-block-film-trans-delta);
}
The overflow attribute was extremely key, and it's something didn't previously know much about. Giving a scroll value to the entire body (the thing that needed to be able to move up and down) was the answer, as well as giving the innermost element (block-film) the min-height to ensure it stretched itself and subsequently all of the parent elements.
I know you said you've tried every combination, but what about:
html, body {
height: 100%;
}
.fill-height {
min-height: 100%;
height:auto !important; /* cross-browser */
height: 100%; /* cross-browser */
}
The problem with setting min-height: 100% on the body, is that height: 100% on the child div does not actually have a proper parent height to reference, and will not work.
EDIT:
This logic applies to all child divs. So in your case, the body-film div is a child of container-fluid. Because container-fluid now has a min-height of 100%, and not a defined height (it is set to auto), when you give a height percentage to body-film, it doesn't have a height to reference. It's worth having a read of MDN - CSS height and MDN - CSS min-height.
In other words, if you wish to have a div with a height or min-height of 100%, then all of its parent elements need to have a defined height of 100%, all the way up to the html tag.
What you may need to do is something like this:
html, body {
height: 100%;
}
.container-fluid {
height: 100%;
overflow-y: hidden; /* don't show content that exceeds my height */
}
.body-film {
min-height: 100%;
overflow-y: scroll;
}
This may not be the definitive answer as it depends on what you want exactly, but hopefully this sets you on the right track.
