flexbox model not producing 100% height of parent container - html

Using the following CSS:
#menusidebar {
background-color: #6BC9DB;
margin: 0 0 0 0;
height: 100vh;
}
the left hand side sidebar of this page does not reach the bottom of its parent container #content-wrap.
Update: I tried using the flex box model:
.flex {
display: -webkit-flex;
display: flex;
flex-grow: 1;
}
<div id="content-wrap" class="fluid clearfix flex" data-content="content">
<aside role="complementary" class="two columns" id="menusidebar">
but the child of the flex element #menusidebar does not take up all remaining space of the flex parent #content-wrap.

Here is a start for you, using your sample link
Fiddle demo
where I changed these rules
#content-wrap {
background-color: #FFF;
margin: 0;
display: flex;
}
.column, .columns {
display: inline;
flex: 1;
margin-left: 10px;
margin-right: 10px;
}
#menusidebar {background-color: #6BC9DB; margin: 0 0 0 0;}

Stick with the flexbox strategy, as that one is the most forward-thinking. Add the following style to the container:
align-items: stretch;
And take off any heights set on the child elements (specifically #menusidebar).

CSS Flex stretching out links

So I am learning a bit more about using CSS flex instead of using static positioning of content. However, I have defined my link styles as well as bold styles. My guess is that it's adapting to the container that is in (which is using flex feature) and that is why it is stretching across the size of the container it is inside. My question now is, how do I fix this? I've seen that I can do "display:inline-block" on the link, but that has not fixed it.
Here is my code:
.container{
display: -webkit-flex;
display: flex;
-webkit-flex-flow: row wrap;
flex-flow: row wrap;
width: 80%;
margin: auto;
background-color:#fff;
overflow: hidden;
font-size: 15px;
line-height: 20px;
padding:1em;
}
.container > * {
padding: 15px;
-webkit-flex: 1 100%;
flex: 1 100%;
}
a{
text-decoration:none;
border-bottom-style:double;
border-bottom-width:2px;
color:#99d3df;
display:inline-block;
padding:0px;
overflow: hidden;
}
i{
display:inline-block;
color:#88bbd6;
text-decoration:italic;
}
And what I have:
This is a Google Link<BR>
Google is <i>extremely helpful</i>!
This is what it looks like for reference.
Problem image
It seems you missed the .container wrapper div in the markup you provided.
Let's look at this code:
<!-- HTML -->
<div class="container">
<span>This is a </span><a href="http://google.com">Google Link</a
</div>
<div class="container">
<span>Google is </span><i>extremely helpful</i>!
</div>
<!-- /HTML -->
/* CSS */
.container > * {
padding: 15px;
-webkit-flex: 1 100%;
flex: 1 100%;
}
Property flex with value of 1 100% means we tell the browser to style any elements (the asterisk *) nested in .container to have 100% width of their parent's width.
I would suggest you to just remove that part to fix the problem.
Here's my approach to your markup.
.container {
display: flex;
width: 80%; /* flexible value */
flex-direction: row; /* this is to make sure that we'll have side-to-side layout within .container */
}
a {
text-decoration: none;
border-bottom-style: double;
border-bottom-width: 2px;
color: #99d3df;
display: inline-block;
padding: 0px;
}
a, i{
margin-left: 5px; /* this is to give a 10px spacing */
}
<div class="container"><span>This is a </span>random link<span></span></div>
<div class="container"><span>Google </span><i>is extremely helpful! </i></div>
It is working fine when I tried your code in js fiddle
see in this image
May be some other css is affecting your links to stretch it out.

Display:flex and scrolling inner divs

https://jsfiddle.net/wqmm0kxb/5/
html:
<div class="full">
<header><h1>header stuff</h1></header>
<section>
<div>
{lots and lots of content}
</div>
<div>b</div>
<div>c</div>
</section>
</div>
css:
.full {
position: fixed;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
display: flex;
flex-direction: column;
header {
flex: 78px 0 0;
background: #ececec;
color: black;
padding-left: 33px;
}
section {
flex: auto 1 1;
display: flex;
align-items: stretch;
> div {
flex: auto 1 1;
overflow-y: auto;
}
}
}
My outer container, '.full', takes up the full width and height of the screen, and uses display:flex to make sure that the header + section children stretch to take up all the space beneath them.
Now, what I want is naturally for the header to take up 78px and the section to take up {full height - 78px} -- but without doing anything like calc preferrably. And I want to be able to scroll in the div children of section, without scrolling affecting the other divs or the page as a whole.
This works perfectly in Chrome, but open up my fiddle in firefox, edge, ie and it doesn't work as expected. Section gets the height of {lots and lots of content} rather than only taking the remaining space of '.full'
What should I do to achieve the Chrome-like layout that I'm expecting?
Apply the overflow-y:auto for your section also, that will fix the issue in IE and Firefox.
section {
flex: auto 1 1;
display: flex;
align-items: stretch;
overflow-y: auto;
> div {
flex: auto 1 1;
overflow-y: auto;
}
}
Fiddle DEMO

Why is the following flexbox on the left rather than the top?

This is my flexbox setup:
section[_v-f4d9afa6] { // parent
display: flex;
}
article[_v-e514def2] { // child
display: flex;
flex: 1 1 50%;
}
article header[_v-e514def2] { // child of child
background-color: #484a47;
padding: 5px 0;
border-radius: 3px 3px 0 0;
}
article section[_v-e514def2] { // child of child 2
margin: 10px;
flex: 1 1 50%;
overflow-y: scroll;
}
I get this:
What should I change so the dark gray child is on the top? (Like an OS window)?
JSFiddle: https://jsfiddle.net/qjog7tvu/3/
You need to add flex-direction: column; for article[_v-e514def2]
One thing you can do is remove display: flex from article and just let it default as article and section are block element so header will arrange itself to top of section.

get the height of the previous element

Can i get the height of the previous element using only CSS?
I am using calc() function to set dynamically height of the div B.
#b{
height:calc(100vh - heightOfPreviousElement);
}
I need to know the height of the previous element.
what i know is that, 100vh is equal to 100% of the screen height.
I used the code in the answer below.Using flex,
I have one problem. The height of the color orange become smaller.
You can easily achieve the effect you're looking for using flexbox. The trick is to allow the blue container (the one with the flexible height) to grow in size whenever the need arises, using flex: 1 1 auto, which is simply a shorthand for:
flex-grow: 1;
flex-shrink: 1;
flex-basis: auto;
See proof-of-concept code snippet below:
body {
padding: 0;
margin: 0;
}
.wrapper {
display: flex;
flex-direction: column;
flex-wrap: no-wrap;
align-items: center;
justify-content: center;
height: 100vh;
}
.wrapper > div {
width: 100%;
}
#c1 {
background-color: #880015;
color: #fff;
height: 60px;
margin-bottom: 10px;
}
#c2 {
background-color: #ff7f27;
}
#c3 {
background-color: #00a2e8;
flex: 1 1 auto;
margin-bottom: 10px;
}
<div class="wrapper">
<div id="c1">height: 60px</div>
<div id="c2">height: auto (determined by content?)</div>
<div id="c3">flexible height</div>
</div>
No you can't select a previous element in CSS.

Make two flex items each 50% height of parent

I am using css flex layout to build a dashboard and would like to put two widgets (one on top of the other) inside of a flex item and make them 50% height of their parent at all times (regardless of content). So if my html is:
<div class="flex-container">
<div class="flex-item">
<div class="widget" id="w1">
widget 1 content
</div>
<div class="widget" id="w2">
widget 2 content
</div>
</div>
</div>
and my css looks like:
.flex-container {
display: flex;
flex-direction: column;
}
.flex-item {
flex: 1;
}
How can I get the two .widgets to always occupy 50% height of .flex-item?
I've tried:
.flex-item {
flex: 1;
display: flex;
}
.widget {
flex: 1;
}
But this only works when the content in both widgets are the same.
I've worked up a more elaborate jsfiddle to better illustrate my issue.
Thanks in advance!
When you say that flex: 1 only works when the content in both widgets are the same, that is not correct. That would defeat the purpose of flex: 1.
flex: 1 tells flex items to distribute container space evenly among themselves. If there are four flex items with flex: 1, each will take 25%. Three would take 33.33%. And two flex items will take 50%. This is regardless of content quantity.
See this illustration: DEMO
The problem you're having is not clear in the code you posted in the question. However, it's apparent in your fiddle demo.
You have a main container with a height: 400px. You also have a rule adding 10px padding all-around to your divs. This adds 20px height to each div. You also have a header with height: 2em.
When you account for the extra heights the layout works.
Try these adjustments:
HTML (no changes)
CSS
div {
box-shadow: inset 0 0 0 1px rgba(30, 100, 200, 0.5);
padding: 10px; /* sneaky villain */
font-family: arial;
}
h1, p { margin: 0; }
#main-wrapper {
height: 400px; /* primary height */
display: flex;
flex-direction: column;
}
#header {
flex-shrink: 0;
height: 2em; /* header height */
}
#main-column-wrapper {
flex: 1;
display: flex;
flex-direction: row;
height: calc(100% - 2em - 20px); /* primary height - header height - padding */
}
#side-column {
width: 20%;
flex-shrink: 0;
}
#main-column {
flex: 1;
display: flex;
flex-direction: column;
height: calc(100% - 40px); /* main-column-wrapper height - padding (2 divs) */
}
#widget1,
#widget2 {
flex: 1;
flex-shrink: 0;
overflow: auto;
}
Revised Fiddle
Another option would be to use box-sizing: border-box to adjust for the padding. Learn more here: https://css-tricks.com/box-sizing/
