Create rows in html which will share height? - html

<div class="container-fluid">
<div calss="row" style="height:20%; display: block;">
<h1>20 percent height</h1>
</div>
<div calss="row">
<h1>height should be 80 percent</h1>
</div>
</div>
I tried some example which is shown here but it's not working.
My requirement is if i keep first height as 10% or 20% second row should occupy height automatically without setting the height explicitly.

Use flexbox for this type of stuff. Also instead of 80 and 20 you could use 4 and 1, it's just the ratio that matters
.parent {
display: flex;
width: 100vw;
height: 100vh;
flex-direction:column;
}
.top {
flex: 80;
background: red;
}
.bottom {
flex: 20;
background: blue;
}
<div class="parent">
<div class="top"></div>
<div class="bottom"></div>
</div>

Use flex display. Add display: flex and flex-direction: column for the parent and for the second content provide flex-grow: 1 which will fit that div in rest of the space.
.container-fluid {
display: flex;
flex-direction: column;
height: 500px;
}
.container-fluid div {
margin: 5px;
border: 1px solid black;
}
.row-two {
flex-grow: 1;
}
<div class="container-fluid">
<div class="row" style="height:20%; display: block;">
<h1>20 percent height</h1>
</div>
<div class="row row-two">
<h1>height should be 80 percent</h1>
</div>
</div>

How can I accomplish this design with flexbox?

I'm trying to accomplish this design by using flexbox:
It's supposed to be a one page website.
.container {
display: flex;
}
.big {
flex: 2;
height: 70vh;
background: gray;
}
.small {
flex: 1;
height: 70vh;
background: gray;
}
<div class="container">
<div class="small">
</div>
<div class="smallest">
</div>
<div class="big">
</div>
</div>
I have no idea how to implement the "smallest" div to be 25% of the big, let alone make the "small" 75% of the big one.
Also the height really confuses me, I need them to always have the same height.
With flexbox you can wrap the small and the smallest into a separate div and use column flexbox on the left section.
I have no idea how to implement the "smallest" div to be 25% of the big
25% to 75% ratio means 1:3 ratio - and in flexbox language that is flex: 1 to the small element and flex: 3 to the big element.
Also the height really confuses me, I need them to always have the same height.
You can set the height of the container to the container element - your flexbox will fill to this height.
See demo below:
.container {
display: flex;
height: 70vh;
}
.big {
flex: 3;
background: gray;
margin-left: 5px;
}
.left {
flex: 1;
display: flex;
flex-direction: column;
}
.left .small {
background: gray;
flex: 3;
}
.left .smallest {
margin-top: 5px;
background: gray;
flex: 1;
}
<div class="container">
<div class="left">
<div class="small">
</div>
<div class="smallest">
</div>
</div>
<div class="big">
</div>
</div>

place two divs per row

so I have X divs and I want to put 2 divs in one row next to each other. If the screen size width is below n px there should be 1 div per row.
Currently I have this
#container {
display: flex;
}
.box {
width: 50px;
background: red;
}
#media(max-width: 300px) {
#container {
display: block;
}
}
<div id="container">
<div class="box"> 1 </div>
<div class="box"> 2</div>
<div class="box"> 3 </div>
<div class="box"> 4 </div>
</div>
How can I limit the flex box to two divs per row?
Add 50% width on .box and flex-wrap:wrap on the container
Additionally, what you did by changing display: flex to block was not required. Just change the .box elements width to 100%
#container {
display: flex;
flex-wrap: wrap;
}
.box {
width: 50%;
background: red;
}
#media(max-width: 300px) {
.box {
width: 100%;
}
}
<div id="container">
<div class="box"> 1 </div>
<div class="box"> 2</div>
<div class="box"> 3 </div>
<div class="box"> 4 </div>
</div>
Just add a property in your container class like
.container {
display: flex;
flex-wrap: wrap;
}
And in box class just specify the width of your box as 50% like
.box {
width: 50%;
background: red;
}
That should do the trick.
Flex will do a trick for you. flex-wrap: wrap for #container will make children wrap when necessary. .box with 50% and after breakpoint 100%.`
According to MDN:
The CSS flex-wrap property specifies whether flex items are forced into a single line or can be wrapped onto multiple lines. If wrapping is allowed, this property also enables you to control the direction in which lines are stacked.
If you are new to flexbox I recommend this guide.
Snippet
#container {
display: flex;
flex-wrap: wrap;
}
.box {
width: 50%;
background: red;
}
#media(max-width: 300px) {
.box {
width: 100%;
}
}
<div id="container">
<div class="box"> 1 </div>
<div class="box"> 2 </div>
<div class="box"> 3 </div>
<div class="box"> 4 </div>
</div>

How can I get even heights of unknown elements inside a column? [duplicate]

This question already has answers here:
Equal height flex items in flex columns
(3 answers)
Closed 5 years ago.
I'm using flex to create even columns and vh to make them the same height. That's working fine but inside the columns I can have an x number of items in them. I'd like for elements in each column to be even height depending on how many items are present (using css).
1 = 100%
2 = 50%
3 = 33.33%
etc.
I know I can do this through JS but I'd like to automate this through css via flex, grid, or something elese.
I've tried replicating your problem. Use flex: 1 on .items so that each and every item take equal space (according to the problem statement).
Have a look at the snippet below:
body {
margin: 0;
}
.parent {
width: 80%;
padding: 20px;
display: flex;
border: 1px solid red;
}
.child {
flex: 1;
display: flex;
flex-direction: column;
align-items: stretch;
justify-content: flex-end;
padding: 20px;
border: 1px solid blue;
height: 60vh;
}
.item {
flex: 1;
background: lightGreen;
border: 1px solid green;
}
<div class="parent">
<div class="child">
<div class="item">33.33%</div>
<div class="item">33.33%</div>
<div class="item">33.33%</div>
</div>
<div class="child">
<div class="item">50%</div>
<div class="item">50%</div>
</div>
<div class="child">
<div class="item">100%</div>
</div>
</div>
Hope this is what you are trying to achieve.
This is all you need to make it work with the Flexbox:
.flex-container {
display: flex;
}
.flex-item {
display: flex;
flex-direction: column;
flex: 1;
}
.item {
flex: 1;
border: 1px solid;
}
<div class="flex-container">
<div class="flex-item">
<div class="item">1/1</div>
</div>
<div class="flex-item">
<div class="item">1/2</div>
<div class="item">1/2</div>
</div>
<div class="flex-item">
<div class="item">1/3</div>
<div class="item">1/3</div>
<div class="item">1/3</div>
</div>
<div class="flex-item">
<div class="item">1/4</div>
<div class="item">1/4</div>
<div class="item">1/4</div>
<div class="item">1/4</div>
</div>
</div>

How to use `flex: grow` on floating content?

I have a header with 2 rows of 2 Foundation columns of content, as below:
<div class="wrapper">
<div class="header row">
<div class="large-6 columns">
HEADER
</div>
<div class="large-6 columns">
menu
</div>
</div>
<div class="row">
<div class="large-5 none show-for-medium columns info">
Some information to the left
</div>
<div class="large-7 columns">
<div class="image-container">
<div class="image">
image to the right
</div>
</div>
</div>
</div>
</div>
The .header height is dynamic and not set. I want the .image element to take up 100% of the remaining vertical space.
eg:
To that affect I have tried using flex and flex-grow, eg:
.wrapper {
display: flex;
flex-direction: column;
min-height: 100vh;
width: 100%;
}
.image-container {
flex-grow: 1;
}
but had no luck, see fiddle: https://jsfiddle.net/9kkb2bxu/46/
Would anyone know how I could negate the dynamic height of the header from the 100vh of the image container?
.wrapper {
display: flex;
flex-direction: column;
min-height: 100vh;
width: 100%;
border: 1px solid black;
background-color: #ccc;
}
.row {
width: 100%;
}
.header {
background-color: green;
}
.info {
background-color: yellow;
border: 1px solid #ccc;
}
.image-container {
border: 1px solid black;
display: flex;
}
.image {
background-color: red;
flex-grow: 1;
width: 100%;
}

</div>
<div class="large-7 columns">
<div class="image-container">
<div class="image">
image to the right
</div>
</div>
</div>
</div>
</div>
Set the second row to take up the rest of the remaining height with flex: 1 and make sure you nest that flex with display: flex:
.row.target-row {
flex: 1;
display: flex;
}
Set the .image-container to 100% height of its column parent.
.image-container {
height: 100%;
}
By default both columns will expand. Stop the left column from expanding with:
.large-5 {
align-self: flex-start;
}
(flex-start reference: https://stackoverflow.com/a/40156422/2930477)

flex-grow only applies to flex children.
.image-container isn't a direct child of a display: flex element, so that property has no effect.
Plus, it affects the flex axis, which is not what you want.
Instead, you need to put those two elements in their own flex row, and use align-items (on the parent) and align-self (on either child) so that the first one aligns (on the cross axis) to flex-start (stick to top) and the second one to stretch.
You'll also want that flex row (parent) to have flex-grow: 1 so that it stretches along the vertical flex axis of its parent (.wrapper) to fill the rest of the page (otherwise, the grandchild will have nothing to stretch to).
For more information, read a good flex tutorial.
div.wrapper > div:not(.header).row {
flex: 1; /* 1 */
display: flex; /* 1 */
}
div.large-7.columns {
display: flex; /* 2 */
}
div.image-container { /* 3 */
flex: 1;
}
div.large-5.show-for-medium { /* 4 */
align-self: flex-start;
}
jsFiddle
Notes:
flex container and items consume all remaining height of respective parents
give children full height (via align-items: stretch initial setting)
flex item consumes all available width
yellow box does not need to expand to full height; now set to content height

Style one single column with flexbox

Maybe I want something impossible.
I want a website with only a single column styled with flexbox. The purpose is that only one column stretches its height to the footer regardless the size of the content of the column. Something like below structure:
I try to reach that with this code (I am using bootstrap):
<div class="container-fluid">
<div class="row">
<header class="col-md-12">
stuff...
</header>
<div class="col-md-1 col-a">
stuff...
</div>
<div class="col-md-10 col-b">
Stuff...
</div>
<div class="col-md-1 col-c">
<div class="col-c-child">
Stuff..
</div>
</div>
<footer class="col-md-12">
Stuff
</footer>
</div>
</div>
And then adding in the CSS this specific for the col-c and col-c-child:
.col-c {
display: flex;
flex-direction: column;
height: 100%;
}
.col-c-child {
flex: 1;
}
But is not working.
Any idea?
THE SOLUTION:
Create a row for the header, other for the content and other for the footer, that is - don't have everything in the same row.
Build a div-wrapper englobing col-a, col-b and col-c with display:flex and flex-direction: row;
get rid of col-c-child
col-c with flex: 1;
Thanks to #jelleB who elucidated me for part of it.
Put the header and the footer in different rows.
You should build a div below col-a (without content)
Use min-height: 100% on the row where you put col-a/col-b/col-c in
Give this a shot
I suspect your problem lies in the height:100%
If I am not mistaken, you cannot do that unless the parent container has its height defined. If the parent container's height is also defined as a percentage then the parent's parent container's height must also be defined. This hierarchy continues up to the body tag.
If you are able to wrap your middle divs, you can do the following:
html,
body {
height: 100%;
padding: 0;
margin: 0;
}
.container {
display: flex;
flex-direction: column;
height: 100%;
width: 100%;
}
.container #body {
display: flex;
flex-direction: row;
flex-grow: 1;
}
header,
footer {
width: 100%;
}
.left,
.right {
width: 100px; /*change to whatever width you want*/
}
.center {
flex-grow: 1;
}
/*styles for demo*/
header,
footer {
height: 50px;
background: blue;
}
.left,
.right {
background: green;
}
.center {
background: red
}
<div class="container">
<header></header>
<div id="body">
<div class="left"></div>
<div class="center"></div>
<div class="right"></div>
</div>
<footer></footer>
</div>
