Flexbox: space-between does not generate space between items [duplicate] - html

This question already has an answer here:
flex-grow not working in column layout
(1 answer)
Closed 4 years ago.
I'm trying to have space between each .box element, however space-between is not acting to create spaces between the boxes. The boxes appear with no space in between them.
* {
box-sizing: border-box;
}
.grid {
border: black dashed 1px;
display: flex;
flex-flow: column nowrap;
justify-content: space-between;
align-items: center;
}
.grid * {
border: 1px red solid;
}
.box {
height: 100px;
width: 100px;
background-color: blue;
}
<div class="grid">
<div class="box">1</div>
<div class="box">2</div>
<div class="box">3</div>
</div>
See codesandbox: https://codesandbox.io/s/8j7k4xjzl

The code is actually working. The problem is the ".grid" div is taking the minimum height required according to it's content.
If you give ".grid" div height equal to 100vh you can see the result.
height: 100vh;
Here's a fiddle showing the result:

Please tell if this is the solution you're looking for.

Space-between is used for horizontal "box spacing". What you're looking for is margin.
.box {
height: 100px;
width: 100px;
background-color: blue;
margin: 5px;
}
like so.

You can edit the top, right, left, bottom margin if you want to do so:
margin: (top) (right) (bottom) (left);

How to create a dynamic navigation bar with one zone of wrapping items, and one zone of not wrapping items

I am trying to build this dynamic navigation bar with two zones, and only set sizes on the menu items. The yellow zone items shall wrap freely while the red zone items shall be presented at the bottom with no wrapping. Can i have some guidance on how to solve this..am totally lost :/
Navigation container
width: Full page
height: Depends on content height
Yellow Zone
width: Full page - red zone
height: Depends on content height
items wraps to x new rows
Red Zone:
width: Depends on content width
height: Same as yellow zone
items does not wrap and are presented on the same row as the last row on the yellow zone
This should do what you are looking for. To do most of the styling I used flex-box, so if you don't know it yet, I suggest you learn it, it's very useful.
What I basically do is use two separate containers to which I'm going to apply a different flex-flow. flex-flow takes the direction (row/column) as the first "parameter" and the wrap (wrap/nowrap) as the second. I add a little gap between the elements and you can style the rest as you prefer.
I'll also link you to the codepen, so you can test it easier.

Div vanishes when i use "align-items : center"

I want to create a box which has on left and right side a blue "div" and in the middle a larger purple "div". My Problem is that when i write "align-items : center" all "div" vanishes but i dont know why. Can you help me?
This is my HTML Code

This is my CSS Code
#anotherExample{

margin: 0 auto;

flex-grow:1 ;
flex-basis: 200px;
}
section .mainContent{
background-color: blueviolet;
flex-grow:2 ;
flex-basis: 200px;
}
It looks like when you apply align-items: center, the height of div elements are set to 0. You can try to add the height property to divs to see them again as #anotherExample is parent of those div elements.
#anotherExample{
width: 90%;

}

All div vanish because they have no height when align-items: center.
For flex items, the default align-items behave as stretch. The three div are stretched to their container height.
When you set align-items: center, the three div are centered on the cross-axis, but they are not visible due to no height (since they do not have content or a set height).
If you give them a height such as height: 100%, you can see the three div again.

#anotherExample {
width: 90%;
height: 500px;
margin: 0 auto;
border: 5px solid #003049;
display: flex;
justify-content: center;
/* 👇 With this turn on the div will no height will vanish */
align-items: center;
}
section .sidebar {
background-color: blue;
flex-grow: 1;
flex-basis: 200px;
/* 👇 Give div a height to see it when align-items is center */
height: 100%;
}

background-color: blueviolet;
flex-grow: 2;
flex-basis: 200px;
/* 👇 Give div a height to see it when align-items is center */

I am unable to center a div both horizontally and vertically [duplicate]

set the height and width of the container to 100vh and 100vw
add height in your parent .container class it will take full height
.container{
display: flex;
justify-content: center;
align-items: center;
height:100vh;
}
.box{
width: 50px;

flex container is reversing items

I have a flex-container with three items and the flex-direction set to row. I put different sizes for each of the three boxes so that they're in an ascending order. item 1 should be 100px, item 2 is 400px, item 3 should be 800px. When I run this, its in reverse. Why is this in reverse and how do I make it not reverse?

/*same thing for above, but for div contents*/

.item:nth-last-of-type(1){
flex-basis: 100px;
}
.item:nth-last-of-type(2){
flex-basis: 400px;
}
.item:nth-last-of-type(3){
flex-basis: 800px;
}
If you use :nth-child() your problem will be solved.
The :nth-child() CSS pseudo-class matches elements based on their position among a group of siblings.
The :nth-last-of-type() CSS pseudo-class matches elements based on their position among siblings of the same type (tag name), counting from the end.
dont make the code complex.
just do this
.flex-container {
display: flex;
flex-direction: row;
}
.flex-container .item {
color: white; \\ to see the items
background: black;
}
if your code make it reverse.
then adding reverse make it reverse again going back to normal:
.flex-container {
display: flex;
flex-direction: row-reverse;
}

Flex shrinking when neighbour wraps

How can I make the shrink element "shrink" when the flex container below grows as a result of flex-wrapping. What is happening now is that new space created below the container instead of shrinking the one above. For some reason flex-grow and flex-shrink are not working expectedly whenever wrap happens. I want everything to fit within the viewport so that the user does not need to scroll.
* {
box-sizing: border-box;
}
body {
margin: 0;
padding: 0;
}
.main-container {
display: flex;
width: 100vw;
height: 100vh;
flex-direction: column;
}
.main-container>* {
text-align: center;
}
.shrink {
background-color: #c0caad;
padding-top: 30%;
height: 80vh;
width: 100vw;
flex-shrink: 0;
}
.grow {
height: 20vh;
width: 30vw;
background-color: #9da9a0;
display: flex;
flex-wrap: wrap;
flex-grow: 1;
}
.grow>* {
border: 5px solid #654c4f;
height: 100%;
background-color: #b26e63;
width: 50%;

There are a few concerns in your CSS. See the working snippet below.
1. flex-shrink: 0; prevents it from shrinking.
For flex-children to be flexibly growing and shrinking, you'd probably want flex: 1; or some other shrink/grow values than 0.
2. explicit height of 80vh and 20vh make them of static height.
That is, they will remain of those specific height rather than flexibly changing their relational heights as you indicated in your drawing. You'd want to remove those values.
3. padding-top: 30% pushes the content down, forcing the height
I wonder if you included it just to push the placeholder text down. But in any case, it's one of the factors that stops the shrink from shrinking.
4. width: 50% + border: 5px - border-box > 50% of available space
Again, this might be just a placeholder style. But in any case, unless you set it to box-sizing: border-box; the width will become 50% + 5px and will unexpectedly wrap.
Below are cleaned up suggestion, based on your drawing in the question.
