So I have a database with x and y quadrants and I have a 350x350px map. I have positioned the map as such:
background-image: url(/storage/maps/surface.png);
background-repeat: no-repeat;
height: 350px;
background-position: center center;
margin: 0px auto;
background-size: cover;
The width seems to be 429px, not sure why. Im sure it has to do with the cover.
On top of this image I have a marker:
font-size: 32px;
color: #f9e4b4;
z-index: 5;
position: absolute;
top: 78px;
left: 349px;
The top represents the Y position and the X position represents the left.
These values (top and left) come from the database and are set in React JS.
This, as it stands creates three divs:
<div class="location-map mb-3">
<div style="background-image: url("/storage/maps/surface.png"); background-repeat: no-repeat; height: 350px; background-position: center center; margin: 0px auto; background-size: cover;">
<i class="fas fa-map-marker-alt player-icon" style="top: 78px; left: 349px;"></i>
</div>
</div>
The issue I am having is:
As you an see, I am trying to position this marker at a pixel perfect position on the map.
now as you see the location states 349, 78 and while this might be right css wise, the marker should be at the edge of the map (on the right) if it was truly 349px's to the left.
So my question is, is the image too small? did I position the image properly? Why is the marker where it is and not where I want it to be?
There are two main items to solve:
The size of the map element should be an exact 350px square
Using top and left should place the base of the pin at the exact coordinates.
Let's start with the map. If you know the exact image dimensions of your image this should suffice:
.map {
background: url(http://placehold.it/350x350);
height: 350px;
width: 350px;
}
<div class="map">
</div>
Now lets create the element we want to position using top and left to the exact pixel, allowing any decoration to fall where it may by using a pseudo element:
.map {
background: url(http://placehold.it/350x350);
height: 350px;
position: relative;
width: 350px;
}
.map-x-pin {
background-color: black; /* So we can see where the pixel is */
height: 1px;
position: absolute;
width: 1px;
}
.map-x-pin::after {
background-color: red; /* Decorative, this could be an image too */
bottom: 100%;
content: '';
display: block;
left: -10px; /* Half of the width, give or take a pixel */
position: absolute;
height: 40px;
width: 20px;
}
<div class="map">
<div class="map-x-pin" style="top: 78px; left: 349px;"></div>
</div>

Image:
I have a container div (yellow) which I’d like to keep at 50% width of the window. A child of that container is an image div (purple) that stretches to 100% of the parent container’s width. and there’s a sticky label (pink) on top of the image div (position: absolute so it can be offset relatively to the image). I'd like to keep that entire half of the screen fixed positioning so it stays sticky as I scroll.
There’s also a title under the image, and that title needs to be visible no matter if someone shrinks the window vertically. So in that scenario the image div should shrink vertically, if needed, in order for that title to be shown.
Basically I'm trying to have the image div always be 100% width of the parent container div. With the image div having a max % height so it can shrink vertically. Or have it keep a fixed aspect ratio (3:4 or whatever) when it shrinks vertically.
I'm trying to avoid using fixed pixels, or ems, in the entirety of my CSS. since the website needs to be stretchy/‘fluid’ vertically, because that title under the image has to show.
HTML looks roughly like:
<wrapper>
<left-column>
<normal text and scrollable stuff>
<right-column-yellow>
<image sticky label-pink>
<image div-purple>
<image title>
Sorry if this is damn confusing my brain is fried! Can anyone pls help me?
You can divide your left and right panel by using position fixed.
If I'm not wrong with your description, this is the answer.
<div class="wrapper">
<div class="left">
<p><!--Some very long text--></p>
</div>
<div class="right">
<div class="image">
<div class="label">Label</div>
<div class="title">Title</div>
</div>
</div>
Some CSS
.left,.right{
position: fixed;
width: 50%;
height: 100%;
display: inline-block;
}
.left{
left:0;
top: 0;
overflow: auto;
}
.right{
right: 0;
top:0;
background-color: yellow;
}
.right .image{
position: relative;
width: 100%;
height: 50%;
top: 50%;
left: 0;
background-color: #fff;
transform: translateY(-50%);
}
.right .image .label{
position: absolute;
left: 0;
right: 0;
top: -10px;
text-align: center;
width: 200px;
background-color: pink;
margin: auto;
}
.right .image .title{
position: absolute;
left: 0;
right: 0;
bottom: -40px;
text-align: center;
width: 200px;
background-color: #000;
margin: auto;
color: #fff;
font-size: 30px;
}

I was wondering if you can help me with this.
I have a div (in white) where I need to put two circular buttons (in green) on the borders. Everything should be done with CSS.
It should look like this:
Screenshot
Now, the thing is that I don't know the size of the white div, and I won't know it at the time of creation, because it will get added to the DOM afterwards. All I know is that the white div has a percentage width and height relative to its future parent. So, at the time of creation, since it's not yet added, any calls to width(), height() or its css values won't work.
I've seen all those snippets that tell you how to make a div with a fixed aspect ratio. I need this now, I need the button to be 1:1, but all I know about the dimensions, is that it has to be 100% of the height of the white div (and therefore, its width should be equal as its height). All the examples I've seen assume that you know the width and to make the height keep the ratio. In my case, what I know is the height (100%) and I want the width to adapt.
I have no idea how to achieve this.
This is my snippet:
body{
background-color: #DCDCDC;
}
.container {
width: 50%;
height: 7%;
background: white;
border-radius: 20px;
position: absolute;
}
.arrow {
background: green;
border-radius: 20px;
height: 100%;
position: absolute;
}
.arrow:after{
content: "";
display: block;
padding-right: 100%;
}
.arrow:last-child {
right: 0;
}
<div class="container">
<div class="arrow"></div>
<div class="arrow"></div>
</div>
https://jsfiddle.net/7bxecL9m/
If you know how can I do this without entering any fixed value (jQuery use is of course valid), I'd really appreciate it.
Thanks.
There are many variables here:
Since container's height is % and circle radius is px units, one is static and the other one will resize.
The only way to preserve 1:1 with just html/css, considering the container's height % will resize circle's height as well, would be to isolate circle's div width & height to something static like px units.
Now, since you said no fixed dimensions, the only thing I can think of is to comment .arrow's 100% height, to prevent resizing other than 1:1, and nesting a div inside .arrow to restrain 1:1 with static units (ideally impacting .arrow directly would be less code but if you don't want/can't set them on that element, maybe you consider this).
If you want the circle to remain circular as the content expands, you need to dynamically adjust the height to match the width. You could use Javascript to achieve this, but your border-radius is tied to container's in px static units, since container will always be bigger something like border-radius: 50% wouldn't work for both, 50% radius of circle would never match 50% of container's (that is, if you care about radius alignment).
body {
background-color: #DCDCDC;
}
body,
html {
height: 100%;
}
.container {
width: 50%;
height: 37%;
background: white;
border-radius: 20px;
position: relative;
}
.arrow {
background: green;
border-radius: 20px;
/*height: 100%;*/
position: absolute;
overflow: hidden;
}
.bLimit {
height: 40px;
width: 40px;
line-height: 40px;
}
.arrow:after {
content: "";
display: block;
padding-right: 100%;
}
.arrow:last-child {
right: 0;
}
<div class="container">
<div class="arrow">
<div class="bLimit">button overflow</div>
</div>
<div class="arrow">
<div class="bLimit">button</div>
</div>
</div>
Why not doing a fixed width in percent for your arrow :
.arrow {
background: green;
border-radius: 20px;
height: 100%;
position: absolute;
width: 10%;
}
body{
background-color: #DCDCDC;
}
.container {
width: 50%;
height: 7%;
background: white;
border-radius: 20px;
position: absolute;
}
.container:after,.container:before{
content: " ";
display: block;
padding: 4%;
z-index: 999;
top: 0;
position:absolute;
background: green;
border-radius: 50%;
}
.container:before {
left: 0;
}
.container:after{
right: 0;
}
<div class="container">
</div>
You can achieve using before and after CSS pseudo selectors. You check this Example.
There is a posibility to get this result using a image (that won't show) of the required ratio.
In this case, the ratio is 1:1 so we will use an image of 50px (but it can be any size)
.container {
width: 300px;
height: 20px;
border: solid 1px blue;
margin: 40px;
position: relative;
}
.container:nth-child(2) {
height: 40px;
}
.container:nth-child(3) {
height: 60px;
}
.arrow {
height: 100%;
background-color: red;
opacity: 0.5;
position: absolute;
border-radius: 50%;
transform: translateX(-50%);
}
.arrow:last-child {
right: 0px;
transform: translateX(50%);
}
img {
height: 100%;
opacity: 0;
}
<div class="container">
<div class="arrow">

My Goal:
So I am making a webpage with a map of the USA as the "background image" and on top of that map I have about 10 markers pointing to specific location. The markers are NOT part of the picture thats just me adding them with absolute positioning and top and left with a percentage.
The Problem:
As I scale down the page or scroll up and down the markers that I have set with absolute positioning begin to move out of the spot they are suppose to be on because the background-image is getting smaller do to it displaying 100%.
The Question:
How can I achieve what I want with the markers on the map where they are suppose to be not moving as the window is being scaled down?
Now I know of only 1 solution and this solution can take a VERY LONG TIME. What I was thinking is instead of positioning the markers that I want on the map with percentage I can do it with pixels and then use a TON of media queries and keep on adjusting it. Not only is this solution going to take extremely long but it also does not seems like the correct way to go about this.
HTML:
<div class="container main-content"><!--the map background image is set here-->
<div class="row relative">
<div class="eq-content-wrap">
<div class="eq-content">
<div class="marker"></div> <!--the marker that is positioned absolute-->
</div>
</div>
</div>
CSS:
html, body{
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
background: #000;
}
body{ overflow: hidden; }
.main-content{
background: url('assets/img/map1.jpg') no-repeat top center;
background-size: contain;
height: 100% !important;
width: 100% !important;
}
.eq-content-wrap{
position: absolute;
width: 500px !important;
top: 22%;
left: 40%;
}
.marker{
height: 40px;
width: 40px;
border-radius: 100%;
background-color: red;
position: absolute;
top: 50%;
margin-top: -20px;
}
The problem is that your background image's size is set to 100%: background-size: 100%. This means that when the browser tries to scale the content, the background does not scale with it (it stays 100%).
Your best bet is to remove the background-size property completely. This allows the markers to stay in place when the page scales, however, you won't get the full-screen background effect that you currently have (unless you have a larger image).
The background will still move, however, once the browser window width is less than the image's width. This is because you have the background-position set to top center. The center is what causes it to move once the browser window width is less than the image width. Change center to left and it will fix that issue. You'll also need to set the marker's container to be based to the left as well for this to work on wider screens though. Basically, removing all center properties would help, but the screen wouldn't be centered on a wide screen.
Try substituting css :before pseudo element for .marker ; set percentage unit values utilizing calc()
html,
body {
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
background: #000;
}
body {
overflow: hidden;
}
.main-content {
background: url(http://lorempixel.com/400/300) no-repeat top center;
background-size: contain;
height: 100% !important;
width: 100% !important;
}
.eq-content-wrap {
position: absolute;
width: 500px !important;
top: 22%;
left: 40%;
}
.main-content:before {
content: " ";
height: calc(12.5%);
width: calc(5%);
border-radius: 100%;
background-color: red;
position: absolute;
top: calc(50%);
left: calc(50%);
margin-top: calc(1%);
}
<div class="container main-content">
<!--the map background image is set here-->
<div class="row relative">
<div class="eq-content-wrap">
<div class="eq-content">
<div class="marker"></div>
<!--the marker that is positioned absolute-->

Hi guys I was trying to swap the background of two images down the footer section of my website using skrollr.js (https://github.com/Prinzhorn/skrollr). For some reason it won't scroll at all. I am trying to create a parallax site that has fixed position on the part below.
See image: http://prntscr.com/6yrckx
Here's the Markup of that part:
<div id="starynight"
data-bottom-top="opacity: 1; background: !url(images/sunny.jpg); background-size: cover;"
data--40-top="opacity: 0.5; background: !url(images/night.jpg); background-size: cover;"
data--50-top="opacity: 0; background: !url(images/night.jpg); background-size: cover;"
data--60-top="opacity: 0.5; background: !url(images/night.jpg); background-size: cover;"
data--70-top="opacity: 1; background: !url(images/night.jpg); background-size: cover;"
>
</div>
While here's the CSS:
#starynight{
background: url('../images/sunny.jpg') no-repeat center;
width: 100%;
height: 307px;
background-size: cover;
}
#road{
background: url('../images/road.jpg') no-repeat center;
width: 100%;
height: 145px;
background-size:cover;
}
#car{
background: url('../images/car.png') no-repeat center;
width: 325px;
height: 125px;
display: block;
position: absolute;
z-index: 9999;
left: 950px;
top: 2100px;
}
My issue here is that when I scroll this part of my website it should swap the images of the sunny.jpg and night.jpg while the car is moving from right to left and also this background image must be fixed in position. For some reason my codes won't just work. Any idea what went wrong?
See my website here: http://goo.gl/aNOCiJ
Animating backgrounds is not like animating positions or "number" data. You can't just transform one background into another by fading them (actually Firefox somehow can animate the transition, but lets not depend on that).
A solution to your problem is having 2 diferent divs for, 1 for your night scene, and other for your sunny sky just in the same position, one over the other and with the sunny one with a higher z-index.
Then what you need to animate on scroll is the opacity of the sunny sky, what makes the night scene appear.
Also I found that your level of scroll isn't enough to fade the opacity of the sunny sky completly, it ends in 0.603448.
Hope it helps, please tell me if this worked.
As stated already, background images can't be animated, only background colors. So you'll have to lay both images on top of each other and fade the top layer in like this -
*Untested
#starynight-wrap {
position: relative;
width: 100%; height: 307px;
}
#starynight-day {
position: relative;
width: 100%; height: 100%;
background: url('images/sunny.jpg');
background-size: cover;
}
#starynight-night {
position: absolute;
top: 0; left: 0;
width: 100%; height: 100%;
background: url('images/night.jpg');
background-size: cover;
}
<div id="starynight-wrap">
<div id="starynight-day"></div>
<div id="starynight-night"
data-bottom-top="opacity: 0"
data--50-top="opacity: 0;"
data--60-top="opacity: 0.5;"

I want to display a horizontal stripe on image to vertical align.
this is my code
Html
<div class="demobox" id="demo-5">
<img src="Untitled-1000x288.jpg" />
<div class="details">
<h3>Play Trialer</h3>
</div>
</div>
css
#demo-5 {
position: relative;
}
.demobox {
float: left;
height: 288px;
overflow: hidden;
width: 1000px;
}
#demo-5:hover .details {
margin-left: 0;
}
#demo-5 .details {
left: 0;
margin-left: -1200px;
opacity: 0.7;
filter:alpha(opacity=70);
position: absolute;
top: 0;
}
.details {
background: none repeat scroll 0 0 #000000;
color: #FF0000;
height: 50px;
margin-top: 119px;
text-align: center;
width: 735px;
}
Now problem is images are not with fixed height & width.And i want to display horizontal
stripe in middle, how can i ?
will greatly appreciate your help !!
You need to set container's css position to relative and absolutelly position the title of the image inside the container.
The trick is in usage of percentage vertical positioning and subtracting half of stripes height via margin-top.
Quick example on jsfiddle.
Edit: I badly read the question... here is the corrected answer :-)
