CSS preserve ratio of circle on top of image - css

I have an image and i want to put 2 circles on top of it, instead of the eyes.
body {
background-color: lightgrey;
color: #fff;
padding: 0;
margin: 0;
}
main {
display: grid;
place-items: center;
position: relative;
}
#container {
min-height: 100vw;
min-width: 100vw;
background: none;
aspect-ratio: 1 / 1;
}
.eye-container {
position: relative;
border-radius: 50%;
background-color: red;
width: 12vw;
height: 12vw;
}
.eye-container.left {
top: -84%;
left: 36%;
}
.eye-container.right {
top: -96%;
left: 51%;
}
.eye {
position: absolute;
bottom: 3px;
right: 2px;
display: block;
width: 3vw;
height: 3vw;
border-radius: 50%;
background-color: #000;
}
img {
max-width: 100%;
min-width: 100%;
}
<main>
<div id="container">
<img id="sponge" src="https://upload.wikimedia.org/wikipedia/en/thumb/3/3b/SpongeBob_SquarePants_character.svg/220px-SpongeBob_SquarePants_character.svg.png">
<div class="eye-container left">
<div class="eye"></div>
</div>
<div class="eye-container right">
<div class="eye"></div>
</div>
</div>
</main>
The current issue is the image is too big, it is stretched.
The initial problem was that the layout was not responsive on mobile, and i've did some changes and now the image is this big.
I've used aspect-ratio: 1 / 1; because top was not working with negative percentage, and with pixels the eyes location is changing if is shrink the window.
Do you have another suggestion, maybe a simplified code will be better.
Thank you.

I'm a noob developer and I felt like, this was a tiny engineering job "LOL" but I did it for you.
So the most important point in this is to keep the image and the eyes in the same position. and to do that, you should position them in a parent container for image and eyes considering four important factors:
1- Parent position: relative; All children position: absolute;
2- All children's width: %; so it can stay in the same spot in its parent whatever the width of the parent is.
3- Eyes and eyeballs positioning top, left, right must be % too for the same purpose.
4- To change the image size, use the parent width. do not change the image size.
If you follow these steps, you can position any element with any image or other element.
* {
border: 1px solid blue;
margin: 0;
padding: 0;
}
.container {
width: 200px; /* use this to change the picture size. do not change it somewhere else */
position: relative;
}
.image {
width: 100%;
}
.eye-container{
position: absolute;
border-radius: 50%;
background-color: red;
width: 12%;
height: 12%;
}
.left-eye {
top: 17%;
left: 36%;
}
.right-eye {
top: 17%;
left: 51%;
}
.eyeball {
position: absolute;
bottom: 3px;
right: 2px;
display: block;
width: 30%;
height: 30%;
border-radius: 50%;
background-color: #000;
}
<div class="container">
<img class="image" src="https://upload.wikimedia.org/wikipedia/en/thumb/3/3b/SpongeBob_SquarePants_character.svg/220px-SpongeBob_SquarePants_character.svg.png">
<div class="left-eye eye-container">
<div class="eyeball"></div>
</div>
<div class="right-eye eye-container">
<div class="eyeball"></div>

For a picture preview I need to put 2 div elements vertically in front of a picture

For a picture preview I want to put 2 invisble divs (red/blue in the picture) in front of a picture for next/previous image functionality.
I would like to have the div ("pictureContainer"/ green bordered zone) to automatically take over the dimension of the containing picture but I can't find a PURE CSS solution without setting the width and the height manually.
.container {
position: fixed;
width: 100%;
height: 100%;
border: 3px solid black;
}
.pictureContainer {
/* I don't want to set width and hight manuyally.
The container should have the size if the contained image. */
height: 50%;
width:300px;
position: relative;
margin: auto;
border: 3px solid green;
}
.leftSide {
background-color: blue;
float: left;
height: 100%;
width: 50%;
opacity: 80%;
}
.rightSide {
background-color: red;
float: right;
height: 100%;
width: 50%;
opacity: 80%;
}
.picture {
position: absolute;
top: 0;
left: 0;
margin: auto;
z-index: -1;
}
<div class="container">
<div class="pictureContainer">
<div class="leftSide"></div>
<img class="picture" src="https://www.9skips.com/wp-content/uploads/2018/01/anger-300x300.jpg">
<div class="rightSide"></div>
</div>
</div>
Also the container should be horizontally aligned.
Note: The full screen white div with the black border is used to close the picture preview.
You should change so the divs have absolut: position, let the image have it's natural size, container should be display: inline-block;
.container {
display: flex;
align-items: center;
justify-content: center;
position: fixed;
width: 100%;
height: 100%;
border: 3px solid black;
}
.pictureContainer {
position: relative;
display: inline-block;
margin: 0 auto;
border: 3px solid green;
}
.picture {
display: block;
}
.leftSide {
position: absolute;
top: 0;
bottom: 0;
left: 0;
background-color: blue;
width: 50%;
opacity: 80%;
z-index: 1;
}
.rightSide {
position: absolute;
top: 0;
bottom: 0;
right: 0;
background-color: red;
height: 100%;
width: 50%;
opacity: 80%;
z-index: 1;
}
<div class="container">
<div class="pictureContainer">
<div class="leftSide"></div>

Overflowing siblings' children the proper way

I have a circular div that represents white circle and the logo. It seems like I wanted it to be.
<div class="whiteCircle">
<div class="image" style="background-image: url('https://www.postnl.nl/Images/marker-groen-PostNL_tcm10-72617.png?version=1');"></div>
</div>
.whiteCircle {
width: 65px;
height: 65px;
background-color: white;
border-radius: 50px;
position: absolute;
left: 0;
right: 0;
margin: 0 auto;
}
Then, I created another rectangle div as a sibling to whiteBox, for the other contents.
<div class="box">
<div class="text">
<h2>Heading</h2>
</div>
</div>
The positioning of both parents looks alright however I couldn't figure out a way to move the Heading above the whiteBox. I played with the combinations of z-index but I read it's not possible to adjust children's z-index and parent at the same time.
What am I doing wrong? What is the proper way of achieving it?
https://codepen.io/anon/pen/mwKrdG
1- Remove the z-index from your parent div.
2- Add z-index to your white-box div, i choose the value 20.
3- Absolute positioning your .text class and make sure the z-index of it is bigger than 20;
The css
body {
background-color: lightblue;
}
.whiteBox {
width: 65px;
height: 65px;
background-color: white;
border-radius: 50px;
position: absolute;
left: 0;
right: 0;
margin: 0 auto;
z-index:20;
}
.image {
text-align: center;
height: 100%;
background: no-repeat center center;
}
.container {
width: 275px;
height: 350px;
background-color: white;
margin: 0 auto;
position: absolute;
left: 0;
right: 0;
margin: 0 auto;
top: 38px
}
.text {
text-align: center;
z-index: 25;
position: absolute;
left: 35%;
}

Firefox not ignoring fixed position elements when outside container width

I wasn't sure of the best way to explain this, but if you look at the example snippet in Chrome or Safari, the orange div does not cause the document to scroll horizontally when the window is narrower than the blue container. This is the desired behavior.
However, in Firefox, if you make the window narrow it counts the orange box as content that needs to be able to be scrolled to, causing the document to scroll to the right in an odd way that shifts the body content to the left and is ugly. What's also strange is that you'll notice the green box on the left DOESN'T cause it to have scrollable space to the left...is this a bug, or why is this happening?
Anyone else encountered this?

You can wrap that in an element that will scale with the viewport and set overflow: hidden on that element. You can also remove the transform: scale() from .banner and use position: absolute on the pseudo elements, unless scale(1) is needed for some reason.

how to center (V,H) div inside div

My problem is that I wanted to have split page by two divs side by side (50% width). Inside of them I wanted to place another divs and make them aligned vertically and horizontally at the same time.
I think that it is possible to make it without JS, but I'm not able to do that.
Can anybody make my two circles placed in the center (V,H) of their parent DIV, which are 50% of width and 100% of height so that when I will resize my window the circles will always be in center (and side by side as is now)?
Here is my code:
<div id="container">
<div class="left">
<div class="kolo1">
sometext1
</div>
</div>
<div class="right">
<div class="kolo2">
sometext 2
</div>
</div>
</div>
And a JSFiddle for that: http://jsfiddle.net/m5LCx/
Thanks in advance in solving my quest :)
It's actually quite simple, all you need to do is to simulate a table-like behaviour:
HTML markup:
<div id="container">
<div>
<div class="half left">
<div class="circle">hello</div>
</div>
<div class="half right">
<div class="circle">world</div>
</div>
</div>
</div>
CSS styles:
html, body {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
#container {
display: table;
width: 100%;
height: 100%;
}
#container > div {
display: table-row;
}
.half {
display: table-cell;
width: 50%;
text-align: center;
vertical-align: middle;
}
.half.left {
background: red;
}
.half.right {
background: blue;
}
.circle {
display: inline-block;
padding: 50px;
border-radius: 50%;
}
.half.left .circle {
background: blue;
}
.half.right .circle {
background: red;
}
Final result http://jsfiddle.net/m5LCx/11/:
Working here http://jsfiddle.net/3KmbV/
add position: relative in .left and .right class and than add margin: auto; position: absolute; top: 0; left: 0; right: 0; bottom: 0; in .kolo1 and .kolo2 class. and remove top position from .left class
try it
body {
background-color: #006666;
margin: 0 auto;
height: 100%;
width: 100%;
font-size: 62.5%;
}
#container {
width: 100%;
min-height: 100%;
height: 100%;
position: absolute;
}
.left {
width: 50%;
min-height: 100%;
float: left;
top: 0;
background-color: #660066;
position: relative;
}
.right {
width: 50%;
min-height: 100%;
float: right;
min-height: 100%;
background-color: #003366;
position: relative;
}
.kolo1 {
background-color: #0f0;
width: 10em;
height: 10em;
border-radius: 5em;
line-height: 10em;
text-align: center;
margin: auto;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
}
.kolo2 {
background-color: #00f;
width: 10em;
height: 10em;
border-radius: 5em;
line-height: 10em;
text-align: center;
margin: auto;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
}
you can give postion: relative to .left and .right.
and give below CSS for to .kolo1 and .kolo2
margin: -5em 0 0 -5em;
position: absolute;
left: 50%;
top: 50%;
Updated demo
Another fiddle. This one uses absolute positioning with negative margins to ensure the circles are always in the centre. CSS looks like this
.kolo1 {
position: absolute;
top: 50%;
left: 50%;
margin-left: -5em; /* this must be half of the width */
margin-top: -5em; /* this must be half of the height */
}
As #Tushar points out, you need to set the position of the parent element to relative also.
Working Fiddle
.kolo1 {
background-color: #0f0;
width: 10em;
height: 10em;
border-radius: 5em;
line-height: 10em;
text-align: center;
margin: 50% auto 0 auto;
}
.kolo2 {
background-color: #00f;
width: 10em;
height: 10em;
border-radius: 5em;
line-height: 10em;
text-align: center;
margin: 50% auto 0 auto;
}
Try adding padding-top:50% for parent divs (having class left and right)

CSS float pixels and percent mixed

Ok, I want this:
For that, I have this HTML code:
<div id="wrapForCenter">
<div id="title">
title
</div>
<div id="contentFrame">
<div id="imagePlaceholder">
image
</div>
<div id="content">
content
</div>
</div>
<div id="buttonsBar">
buttonsBar
</div>
</div>
And I have this CSS code:
#wrapForCenter
{
position: absolute;
top:50%;
left: 50%;
margin-top: -160px;
margin-left: -240px;
width: 480px;
height: 320px;
border: 1px solid black;
}
#title
{
width: 100%;
height: 40px;
background-color: Blue;
}
#contentFrame
{
height: 240px;
width: 480px;
}
#imagePlaceholder
{
float: left;
width: 100px;
height: 100%;
background-color: Green;
}
#content
{
float: left;
width: 380px; /*<-- look at this*/
height: 100%;
background-color: Yellow;
overflow: auto;
}
#buttonsBar
{
clear: left;
width: 100%;
height: 40px;
background-color: Silver;
}
If I change the contents width to 100%, why occurs this?
What I spect is that content width would be contentFrame minus imagePlacehoder width in pixels, but when I specify float:left for both, imagePlacehoder and content, content gets its parent container width. Why?
Is there another way to get the same result without using float (maybe display:inline)? And using width:100% for content?
Thank you very much. CSS is not my strenght.
This is called a float drop. Floats work such that they'll fit side-by-side as long as there's enough room for each, but a float will bump down below the previous one if there's not enough room for it to fit.
width:100% means make it 100% as wide as its container (#wrapForCenter). Naturally, if you tell something to be the entire width of it's container, nothing can fit along either side inside of that container, so as a float it must move down below whatever is before it (an earlier "sibling") to fit.
A question similar to this was asked by me myself in stackoverflow before.
How to auto adjust (stretch) div height and width using jQuery or CSS
You can set HTML like;
<div id="container">
<div id="top"></div>
<div id="left"></div>
<div id="right"></div>
<div id="bottom"></div>
</div>
And CSS like;
#container {
position: relative;
width: 300px;
height: 200px;
}
#top, #left, #right, #bottom {
position: absolute
}
#top {
top: 0;
width: 100%;
height: 50px;
background: #00b7f0
}
#left {
top: 50px;
width: 50px;
bottom: 50px;
background: #787878
}
#right {
top: 50px;
left: 50px;
right: 0;
bottom: 50px;
background: #ff7e00
}
#bottom {
bottom: 0;
width: 100%;
height: 50px;
background: #9dbb61
}
Here is the working demo.
Hope this helps..
Note: I recommend (not forcing) you to do a search in stackoverflow before asking questions.
You should set your image holder to 25% and your content to 75%, or if you know how much space you have allocated for your entire content area(picture and content) then subtract 100 from that and use that many pixels. but overall this should work
#wrapForCenter {
position: absolute;
top: 50%;
left: 50%;
margin-top: -160px;
margin-left: -240px;
width: 480px;
height: 320px;
border: 1px solid black;
}
#title {
width: 100%;
height: 40px;
background-color: Blue;
}
#contentFrame {
height: 240px;
width: 480px;
}
#imagePlaceholder {
float: left;
width: 25%; /* See Here */
height: 100%;
background-color: Green;
}
#content {
float:right;
width: 75%; /* And here */
height: 100%;
background-color:Yellow;
}
