How to show an animation that is hidden behind a colored div using a "reveal" div on the surface

Closed 2 years ago.
I want to make a child element be able to see through its parent, so that the background image is visible inside the child but not the parent element, as in the picture below
Is that possible with CSS or with what else ?
As far as I know, you cant subtract one element from another to create this effect, you have to fake it. Consider the white strip as 3 elements sitting next to each other. The outer ones have a white fill, and the center is transparent. These 3 elements sit inside a wrapper that has a white border (to create the white edges). This effect is demonstrated in the example below.
img {
width: 100%;
}
.center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
.row {
display: flex;
flex-direction: row;
width: 100%;
height: 100px;
border: 5px solid white;
}
.row .col {
display: inline-block;
height: 100%;
background-color: white;
width: 100%;
}
.row .col.m {
background-color: transparent;
width: 500px;
}
.row .col span {
color: white;
text-align: center;
}

Padding for Inline Elements
(3 answers)
Closed 4 years ago.
I have a link that looks like a button and I would like to set the background colour to be different.
However, I don't understand why my holder div does not take the same height as it's child. I doesn't take into consideration padding.
Is there a clean way to fix this?
.link {
background-color: green;
padding: .9rem 3rem;
}
.holder {
background-color: red;
text-align: center;
margin-top: 40px;
}
<div class="holder">
LINK
</div>
You need to add display: inline-block to your .link element:
.link {
background-color: green;
padding: .9rem 3rem;
display: inline-block;
}
.holder {
background-color: red;
text-align: center;
margin-top: 40px;
}
<div class="holder">
LINK
</div>
By default, <a> elements are display: inline, and do not have their layout impacted by the containing block. That is to say, they do not allow for a height or width to be set, and do not respect vertical padding and margins.
The <a> tag default display is inline, so its parent will display it vertically along its line box (based on the vertical-align property), you need to change it to display: block or inline-block, depending on what you’re looking for;
.link {
display: block;
background-color: green;
padding: .9rem 3rem;
}
.holder {
background-color: red;
text-align: center;
margin-top: 40px;
}
<div class="holder">
LINK
</div>
Because by default a tag will have the property of display: inline; so make sure to change the anchor tag to display: inline-block; or display: block;

Margin on child element moves parent element
(18 answers)
Closed 6 years ago.
If static positioned elements are not affected by the top, bottom, left, and right properties, why does the box move along with the container when I change the margin-top value of the box element?
I have kept my code at: https://jsfiddle.net/b9rtwkq7/5/
HTML:
<div class="container">
<div class="box">
</div>
</div>
CSS:
.container
{
width:500px;
height: 500px;
background-color: grey;
margin-top: 00px;
}
.box
{
width:100px;
height: 100px;
background-color: orange;
margin-top: 100px;
}
The margins are collapsed in the jsfiddle you posted: https://www.w3.org/TR/CSS2/box.html#collapsing-margins
Add overflow: auto/hidden to .container or use the following css which I've added in a class called .no-collapse myself:
.no-collapse:before {
content: "";
display: table;
}

Why doesn't the height of a container element increase if it contains floated elements?
(7 answers)
Closed 8 years ago.
The div#inner1 and div#inner2 are inside the div#outer, but still the height of div#outer shows as 0px with height:auto.
How do I get the height of the child elements for the outer div?
This is my code:
#outer {
width: 300px;
height: auto;
background: #ccc;
}
#inner1 {
float: left;
width: 100px;
height: 100px;
background: #f00;
}
#inner2 {
float: left;
width: 100px;
height: 100px;
background: #0f0;
}
<div id="outer">
<div id="inner1"></div>
<div id="inner2"></div>
</div>
Add overflow:auto to the div with id outer. This will solve your problem.
Demo
Float the outer div. that will cover your all height, whatever the inner divs holding heights. But if you will provide your inner div float property. then i will suggest you to use the hack clearfix..
/* Assuming this HTML structure:
<div class="clear">
<div class="floated"></div>
<div class="floated"></div>
<div class="floated"></div>
</div>
*/
.clear:before, .clear:after {
content: "\0020";
display: block;
height: 0;
overflow: hidden;
}
.clear:after {
clear: both;
}
try this it will sure work
I'm trying to vertically center a span or div element within another div element. However when I put vertical-align: middle, nothing happens. I've tried changing the display properties of both elements, and nothing seems to work.
This is what I'm currently doing in my webpage:
.main {
height: 72px;
vertical-align: middle;
border: 1px solid black;
padding: 2px;
}
.inner {
vertical-align: middle;
border: 1px solid red;
}
.second {
border: 1px solid blue;
}
<div class="main">
<div class="inner">
This box should be centered in the larger box
<div class="second">Another box in here</div>
</div>
</div>
Here is a jsfiddle of the implementation showing that it doesn't work: http://jsfiddle.net/gZXWC/
Using CSS3:
<div class="outer">
<div class="inner"/>
</div>
Css:
.outer {
display : flex;
align-items : center;
}
use "justify-content: center;" to align elements horizontally
Note: This might not work in old IE's
This seems to be the best way - some time has passed since my original post and this is what should be done now:
.main {
display: table;
/* optional css start */
height: 90px;
width: 90px;
/* optional css end */
}
.inner {
border: 1px solid #000000;
display: table-cell;
vertical-align: middle;
}
<div class="main">
<div class="inner"> This </div>
</div>
Try this, works for me very well:
/* Internet Explorer 10 */
display:-ms-flexbox;
-ms-flex-pack:center;
-ms-flex-align:center;
/* Firefox */
display:-moz-box;
-moz-box-pack:center;
-moz-box-align:center;
/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;
-webkit-box-align:center;
/* W3C */
display:box;
box-pack:center;
box-align:center;
Setting the line-height to the same height as it's containing div will align content in the middle vertically;
DEMO http://jsfiddle.net/kevinPHPkevin/gZXWC/7/
.inner {
line-height:72px;
border: 1px solid #000000;
}
In case you cannot rely on flexbox... Place .child into .parent's center. Works when pixel sizes are unknown (in other words, always) and no problems with IE9+ too.
.parent { position: relative; }
.child {
position: absolute;
top : 50%;
left: 50%;
-ms-transform: translate(-50%, -50%);
transform : translate(-50%, -50%);
}
<div class="parent" style="background:lightyellow; padding:6em">
<div class="child" style="background:gold; padding:1em">—</div>
</div>
You should put vertical-align: middle on the inner element, not the outer element. Set the line-height property on the outer element to match the height of the outer element. Then set display: inline-block and line-height: normal on the inner element. By doing this, the text on the inner element will wrap with a normal line-height. Works in Chrome, Firefox, Safari, and IE 8+
.main {
height: 72px;
line-height:72px;
border: 1px solid black;
}
.inner {
display: inline-block;
vertical-align: middle;
line-height: normal;
}
<div class="main">
<div class="inner">Vertically centered text</div>
</div>
Fiddle
I used this to align everything in the center of the wrapper div in case it helps anyone - I found it simplest:
div.wrapper {
/* --- This works --- */
display: flex;
/* Align Vertically */
align-items: center;
/* Align Horizontally */
justify-content: center;
/* --- ---------- ----- */
width: 100%;
height:100px;
background-color: blue;
}
div.inner {
width: 50px;
height: 50px;
background-color: orange;
}
<div class="wrapper">
<div class="inner">
</div>
</div>
This is a modern approach and it utilizes the CSS Flexbox functionality.
You can now vertically align the content within your parent container by just adding these styles to the .main container
.main {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center; // To center align it horizontally as well
}
You can also use CSS Grids ( a two-dimensional grid-based layout system).
.main {
display: grid;
justify-content: center;
align-content: center;
}
Below is a Shorthand approach but browser support is still low - https://caniuse.com/?search=place-items.
.main {
display: grid; // flex - works for both
place-items: center;
}
And you are good to go!
HTML
<div id="myparent">
<div id="mychild">Test Content here</div>
</div>
CSS
#myparent {
display: table;
}
#mychild {
display: table-cell;
vertical-align: middle;
}
We set the parent div to display as a table and the child div to display as a table-cell. We can then use vertical-align on the child div and set its value to middle. Anything inside this child div will be vertically centered.
Here you have an example of two ways of doing a vertical alignment. I use them and they work pretty well. One is using absolute positioning and the other using flexbox.
Vertical Align Example
Using flexbox, you can align an element by itself inside another element with display: flex; using align-self. If you need to align it also horizontally, you can use align-items and justify-content in the container.
If you don't want to use flexbox, you can use the position property. If you make the container relative and the content absolute, the content will be able to move freely inside the container. So if you use top: 0; and left: 0; in the content, it will be positioned at the top left corner of the container.
Then, to align it, you just need to change the top and left references to 50%. This will position the content at the container center from the top left corner of the content.
So you need to correct this translating the content half its size to the left and top.
here is a great article of how to vetical align..
I like the float way.
http://www.vanseodesign.com/css/vertical-centering/
The HTML:
<div id="main">
<div id="floater"></div>
<div id="inner">Content here</div>
</div>
And the corresponding style:
#main {
height: 250px;
}
#floater {
float: left;
height: 50%;
width: 100%;
margin-bottom: -50px;
}
#inner {
clear: both;
height: 100px;
}
It's simple. Just add display:table-cell in your main class.
.main {
height: 72px;
vertical-align: middle;
display:table-cell;
border: 1px solid #000000;
}
Check out this jsfiddle!
Here is the latest simplest solution - no need to change anything, just add three lines of CSS rules to your container of the div where you wish to center at. I love Flex Box #LoveFlexBox
.main {
/* I changed height to 200px to make it easy to see the alignment. */
height: 200px;
vertical-align: middle;
border: 1px solid #000000;
padding: 2px;
/* Just add the following three rules to the container of which you want to center at. */
display: flex;
flex-direction: column;
justify-content: center;
/* This is true vertical center, no math needed. */
}
.inner {
border: 1px solid #000000;
}
.second {
border: 1px solid #000000;
}
<div class="main">
<div class="inner">This box should be centered in the larger box
<div class="second">Another box in here</div>
</div>
<div class="inner">This box should be centered in the larger box
<div class="second">Another box in here</div>
</div>
</div>
Bonus
the justify-content value can be set to the following few options:
flex-start, which will align the child div to where the flex flow starts in its parent container. In this case, it will stay on top.
center, which will align the child div to the center of its parent container. This is really neat, because you don't need to add an additional div to wrap around all children to put the wrapper in a parent container to center the children. Because of that, this is the true vertical center (in the column flex-direction. similarly, if you change the flow-direction to row, it will become horizontally centered.
flex-end, which will align the child div to where the flex flow ends in its parent container. In this case, it will move to bottom.
space-between, which will spread all children from the beginning of the flow to the end of the flow. If the demo, I added another child div, to show they are spread out.
space-around, similar to space-between, but with half of the space in the beginning and end of the flow.
Since vertical-align works as expected on a td, you could put a single celled table in the div to align its content.
<div>
<table style="width: 100%; height: 100%;"><tr><td style="vertical-align: middle; text-align: center">
Aligned content here...
</td></tr></table>
</div>
Clunky, but works as far as I can tell. It might not have the drawbacks of the other workarounds.
Just put the content inside a table with height 100%, and set the height for the main div
<div style="height:80px;border: 1px solid #000000;">
<table style="height:100%">
<tr><td style="vertical-align: middle;">
This paragraph should be centered in the larger box
</td></tr>
</table>
</div>
To vertically center a span or div element within another div, add position relative to parent div and position absolute to the child div.Now the child div can be positioned anywhere inside the div.Example below centers both horizontally and vertically.
<div class="parent">
<div class="child">Vertically and horizontally centered child div</div>
</div>
css:
.parent{
position: relative;
}
.child{
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}
set below CSS
/*Parent*/
display: table;
/*immediate child*/
display: table-cell;
vertical-align: middle;

THIS IS THE ANSWER:
vertical-align aligns elements relative to the dimensions of the line the element appears in.
reference: https://christopheraue.net/design/why-vertical-align-is-not-working
The question was "WHY?".
The answer: vertical-align only works in certain conditions
in the "display: table-cell;"
