Centering div inside another div and on image - html

I am trying to create a one page website. The idea is to have a div for each image (using bootstrap). This will create the back ground image for the div. Then I want to place another div on where I can place text and other images in. I managed to get it to work using the position from the top but I want to use dimensions relative to the divs so that when it is displayed on a smaller screen the content in the center div is still center and set to the appropriate size.
Here is the div:
<div class="row" id="homeRow">
<img id="homeImage" src="imageSource" alt="Example">
<div class="col-md-8 col-md-offset-2" id="homeTitle">
<img src="headingSource" alt="Handwriting Fonts">
<h3>Some content</h3>
</div>
</div>
There are three of these in on the page. My css at the moment looks like this:
#homeRow{
height: 800px;
width: 100%;
color: white;
overflow:hidden;
}
#homeImage{
width: 100%;
position: relative;
-webkit-filter:brightness(60%);
-moz-filter:brightness(60%);
filter: url(#brightness);
filter:brightness(60%);
}
#homeTitle{
position: absolute;
top: 300px;
width: 50%;
font-family: Verdana, Geneva, sans-serif;
}
So I am looking for a solution that where I will be able to position everything inside of the row div relative to the row div.

#homeRow{
height: 800px;
width: 100%;
color: white;
overflow:hidden;
position: relative;
}
#homeImage{
width: 100%;
position: relative;
-webkit-filter:brightness(60%);
-moz-filter:brightness(60%);
filter: url(#brightness);
filter:brightness(60%);
}
#homeTitle{
position: absolute;
top: 50%;
width: 50%;
left: 50%;
font-family: Verdana, Geneva, sans-serif;
}
Try using this CSS. You can use position relative for outer div and for inside position absolute.

#homerow{
...
position: relative; // add this
}
#homeTitle{
...
//width:50% - remove this
left:25%; // add this
right:25%; // add this
// those left and right will make width 50% and centered
}

contain image in 60%-height-div, while keeping aspect ratio

What I am trying to accomplish:
- create a pop-up div (fixed), centered in view
- this pop-up should be 60% height of the browser window
- the contents of the pop-up should be an image and a 'x' above the upper right corner of the image
- the height of the image should be maximal, considering it should be contained in the div together with the 'x'
- the aspect ratio of the image should be maintained
I tried the following code
<div class="pop-up">
<p class="exit-button">x</p>
<img class="image" src="safari.png" width="1200" height="630" alt="" title="" />
</div>
With CSS:
body {
background: #333;
}
.pop-up {
position: fixed;
height: 60%;
width: auto;
left:50%;
top:50%;
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);
background:yellow;
object-fit: contain;
}
.exit-button {
text-align: right;
margin: 0;
font-size: 300%;
}
.image {
height: 100%;
width: auto;
opacity:0.7;
}
This code is not solving the problem, the image is not contained in the (yellow) div, as can be seen in the following screen shot:
http://www.michielvisser.nl/tmp/screenshot.jpg
How to contain the image in the div with maximal height for the image in the div and maintain aspect ratio?
SOLUTION 1: Remove the height and width from .pop-up and change height:100% in .image to height:60vh. That works perfectly. Apparently the child (img) will not adjust to the parent (div), but the parent (div) will adjust to the child (img). Sounds like real life.
SOLUTION 2: Essentially the problem arises when the window is resized (except in firefox). The solution can be to redraw the image after a resize, this solves the problem:
$(window).resize(function(){
$('img').hide();
setTimeout(function(){ $('img').show(); }, 1);
});
Your problems are:
You have an inline width and height set on your image, which is overriding the CSS styles for width and height on that image
The margin from your X is pushing the image down since the X is wrapped in a <p> tag.
You don't need object-fit at all.
The simple way to solve #1 is to delete the inline width and height from the image tag and leave it to the stylesheet.
Number 2 can be solved by wrapping the X in a div instead of a p, or you can use a pseudo element for it. I have taken the latter approach in the snippet below.
To solve #3, just delete the style from the stylesheet. (Having this property set in Safari actually messed things up for me.)
This snippet is tested in Safari 10.1.1. Note how the placeholder image is quite large by default (1000x800), but it only displays as big as it can per the parent div.
Edit: Based on your comments, let's revise this further so that we dictate the size on the image, and just let the wrapper take up the size of the image.
So on our image, in order to get it to be 60% as tall as the screen, we can do:
img {
height: 60vh;
width: auto;
}
Then, in our parent, we won't specify a width or height at all, but we can do display: flex just to make sure it is big enough to fit its contents.
body {
background: #333;
}
.pop-up {
display: flex;
position: fixed;
left: 50%;
top: 50%;
-webkit-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
background: yellow;
}
.exit {
color: black;
text-decoration: none;
text-align: center;
font-size: 300%;
display: block;
position: absolute;
top: -50px;
right: -40px;
width: 40px;
height: 50px;
}
.image {
height: 60vh;
width: auto;
opacity: 0.7;
}
<div class="pop-up">
X
<img class="image" src="http://placehold.it/1000x800" alt="" title="">
</div>
I put the image above the P tag and added some CSS to .exit-button and .image
From here you can adjust padding and sizing of the elements.
body {
background: #333;
}
.pop-up {
position: fixed;
height: 60%;
width: auto;
left:50%;
top:50%;
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);
background:yellow;
object-fit: contain;
}
.exit-button {
position: absolute;
text-align: right;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: 0;
font-size: 300%;
}
.image {
height: 100%;
width: auto;
opacity:0.7;
}
<div class="pop-up">
<img class="image" src="http://icons.iconarchive.com/icons/johanchalibert/mac-osx-yosemite/1024/safari-icon.png" width="1200" height="630" alt="" title="" />
<p class="exit-button">x</p>
</div>
I copied your code and edited it. Please tell me whether this is the output you wanted or not.
body {
background: #333;
}
.pop-up {
position: fixed;
height: 60%;
width: auto;

top:50%;
padding-top: 30px;
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);

.exit-button {

.image {

}
<div class="pop-up">
<p class="exit-button">x</p>
<img class="image" src="safari.png" alt="" title="" />
</div>
Because of either needing to hardcode in the alignment of the image given the size or deal with weird convolution, I believe this is the best way:
Create a fixed overlay occupying the entirety of the screen, create a container of 60% height, align it in the center with flexbox and stick the image inside making it occupy the entire height. The aspect ratio will update automatically (only happens with height).
As for the button – give it absolute positioning and a right position of 0, and manually give the parent relative positioning (this is necessary).

a {

I believe that's the least amount of convolution if you want it to be dynamic.

Center text inside image dynamically

I have a container div where height and width are set to 100% and position is relative. Inside the div I center an image (image is smaller than div) using display: block and margin:auto. Then I am attempting to center text inside the image using position: absolute, left: 45%, top 82px. Vertical alignment appears to be okay, but as the number of characters in text grows the text is no longer aligned in the middle. So in my image below if text is 4 characters the text would no longer be centered. Is there a better way to dynamically align text?
html:
<div id="countup-container">
<img id="countup-image" src="https://i.stack.imgur.com/9YqKE.png" alt="Accident Free Days">
<span id="ctl00" class="countup-text">101</span>
</div>
Relevant CSS:
#countup-container {
height: 100%;
width: 100%;
position: relative;
}
#countup-image {
display: block;
margin: auto;
width: 300px;
height: 240px;
}
.countup-text {
z-index: 100;
position: absolute;
color: black;
font-size: 40px;
font-weight: bold;
left: 45.3%;
top: 82px;
}
If you are using absolute positioning to center it you would want to change your left: 45%; to left: 50%; then set a transform like this:
.thing_to_center_horizontal {
top 82px;
left: 50%;
transform: translateX(-50%);
}
This will make it center even with dynamic content.
left: 50%; will put it in the center based on the top left corner of the content, then transform: translateX(-50%); will move it 50% of the content's width (this is the dynamic part) to the left making it center.
Make sense?
But maybe a simple text-align: center; might work, but its hard to tell because you did not post any code.
If I understand you, you could simply add text-align:center to your #countup-container.
And remove left:45% to your .countup-text

Image overlapping text and logo not centering on top of image

My header image is overlapping my text and it is very much annoying me. Another thing that is buggy is how my logo text leans right of the center of the image. If someone could help me with both that would be awesome.
Here is my code:
https://jsfiddle.net/c2bom0cc/1/
Here are my tags that are probably the most relevant to this:
#index_header {
position: block;
z-index: 0;
left: 0;
top: 0;
height: 100%;
width: 100%;
text-align: center;
vertical-align: middle;
}
#index_header img {
position: block;
float: left;
width: 100%;
height: 100%;
}
.background_title {
position: absolute;
font-family: 'Montserrat', sans-serif;
color: #FFF;
font-size: 64px;
left: 50%;
top: 50%;
}
<div class="page_container">
<div id="index_header">
<a href="#">
<img alt="slider" id="index_headerimg" src="http://www.bakeryandsnacks.com/var/plain_site/storage/images/publications/food-beverage-nutrition/bakeryandsnacks.com/regulation-safety/coles-freshly-baked-claims-false-rules-federal-court-australia/9101085-1-eng-GB/Coles-freshly-baked-claims-false-rules-Federal-Court-Australia.jpg"
/>
<p class="background_title">G.F. Bakery</p>
</a>
</div>
</div>
I let myself hold a few assumptions on your code:
First, by the full height and width of the image, I figured that you want the image as a stretched background image. So I replaced the <img> with background-image (background shorthand) in CSS Backgrounds.
From your question I see that you want the title in the center of the bakery background.
I did not get what text is overlapped by the image.
If you want text below the image, please put it in an element after <div id="index_header">...</div>, as the background is all over that <div>.
I had to add display:inline-block to .background_title class, so that the vertical-align:middle; would take effect.
I removed all the absolute positioning to handle better with all the alignments.
Absolute positioning make you manually set all the top and left, and it's really difficult to do when your code gets bigger.
Here's you new HTML:
<div class="page_container">
<div id="index_header">
<a href="#">
<p class="background_title">G.F. Bakery</p>
</a>
</div>
<p>Some other content...</p> // this text will not be overlapped by
// #index_header as long as #index_header
// isn't absolutely positioned
</div>
Here's your new CSS:
html, body{ // this is instead of having top:0 and left:0 in #index_header
padding: 0;
margin: 0;
}
.page_container {
height: 100%;
width: 100%;
}
#index_header {
height: 200px;
width: 100%;
text-align: center;
vertical-align: middle;
background: url('http://www.bakeryandsnacks.com/var/plain_site/storage/images/publications/food-beverage-nutrition/bakeryandsnacks.com/regulation-safety/coles-freshly-baked-claims-false-rules-federal-court-australia/9101085-1-eng-GB/Coles-freshly-baked-claims-false-rules-Federal-Court-Australia.jpg') no-repeat center center;
background-size: 100% 100%; // this does the stretching
}
.background_title {
display:inline-block; // this is to apply the vertical-align of parent
font-family: 'Montserrat', sans-serif;
color: #FFF;
font-size: 64px;
}
Here's a JSFiddle
Hope this helps.
If you want your text to be under your image and centered, remove the following code:
.background_title {
position: absolute;
}
Just removing the position will move your text under your image and centered.

div below another absolute positioned div

I have problem with a div below another div which has "position: absolute".
I need to make footer appear UNDER container div but now footer is appearing somewhere behind container.

.footer

width: 100%;
height: 480px;
background-color: green;
}
Absolutely positioned elements will be removed from the flow of the document. So the footer moves up because container is not part of that flow. You would need to either use relative positioning on both, or absolute positioning for both and set their specific top and left values.
Alternatively you could set a top margin on footer that makes it drop enough so it is positioned below the container.
You also need to look at your css. There are several redundant properties that are possibly conflicting.

font-family: arial;
font-size: 17px;

background-color: #34495e;

background-color: #fea;
}
.footer
{
margin-top: 120px;
width: 100%;
height: 80px;
background-color: green;
}
Here in this fiddle I removed some of the redundant css and used position:relative on the container div instead of absolute. The margin-top property on the footer needs to be greater than or equal to the top property on the container in order for it to stay below it.
You can insert another blank div over your non-absolute div and give it height as has your absolute div:
<div class="absoluteDiv">
<p>something</p>
</div>
<div class="blankDiv">
//nothing here
</div>
<div class="myDiv">
<p>some text</p>
<p>Which is covering absolute div</p>
</div>
CSS:
.absoluteDiv {
position: absolute;
left: 0;
}
.myDiv {
position: relative;
width: auto;
padding: 10px;
}
Now we can use JavaScript code to get the height of absolute div and give it to our blank div:
let absoluteDivHeight = document.getElementByClassName('absoluteDiv')[0].offsetHeight;
let blankDiv = document.getElementByClassName('blankDiv')[0];
blankDiv.style.height = absoluteDivHeight + 5 + "px";
Instead of using position:relative, you can keep both of the div with absolute positioning using JavaScript, as that seems closer to what you are looking for.
What you need here is a function that will set the top property of the footer div to the exact value you need it to be.
Here's the code:
document.getElementByClassName("container").style.top = (266 + document.getElementByClassName("footer").offsetHeight) + "px";
Here's the explenation:
document.getElementByClassName().style.top is a HTML DOM method used to change properties through JavaScript, in this case the property is top.
The 266 is the amount of pixels you set for property margin-top for your container div.
The document.getElementByClassName().offsetHeight function gets the height of an element in pixels (including padding and borders).
Finally, we add "px" to the number, so that the top
property is given in pixels.
This method has its pros and cons:
Pros:
the offset is based on the height of the container div, so it is always positioned directly below the div. You can keep using not only position:absolute, but you can use this method also for position:fixed.
Cons: You must rewrite the code if you add another div that would affect the positioning of the footer. The alignment will not change if you resize the window without reloading the page (you can fix this by running the code every time the window height changes.).
Use a separate wrapper div with 100% height and wrap your container in it that way the wrapper is following the standard flow of the page, and the container can be positioned absolutely within that wrapper, let me know if you need code example.

Placing a div below another absolute div

I'm trying to make some header for my website and another div below it, to contain a colored rectangle. Is it possible? I tried it like this so far, but no luck:
.logo {
width: 100%;
left: 0%;
right: 0%;
position: absolute;
}
<div class="logo" onclick="location.href='<%= DefaultPath %>'" style="height:15%; top:0%; background-image:url('<%= LogoPath %>'); background-size: 100% 100%; background-repeat:no-repeat">
</div>
<div style="padding:0%">123</div>
The div that contains "123" should be below the header div. How can I do this?
First of all you should not use so much inline styles. rather use it within a css class (like you did for some code in .logo)
you could use something like this to achieve your positioning:
.header {
position: absolute;
top: 0;
left: 0;
height: 50px;
width: 100%;
background-color: grey;
background-image: url('');
background-position: center center;
background-size: 100% 100%;
}
.numbers {
margin-top: 50px;
height: 100px;
background-color: blue;
width: 100%;
}
and the html is simply this:
<div class="header"></div>
<div class="numbers">123</div>
you would simply place your relative container with a margin-top with the height of your absolute container
i don't really like those absolute px solutions with margins.
if this header should always look like this ( with the triangle and the numbers etc) i would suggest to wrap those two containers into one absolute container and position them both relative like you can find here:
.wrapper {
position: absolute;
top: 0;
left: 0;
width: 100%;
}
.header {
display: block;
height: 50px;
width: 100%;
background-color: grey;
}
.numbers {
height: 100px;
background-color: blue;
width: 100%;
}
<div class="wrapper">
<div class="header"></div>
<div class="numbers">123</div>
</div>
The div below, in this scenario, would need the have a margin-top value equal to the height of the absolute positioned div.
<div class="logo" onclick="location.href='<%= DefaultPath %>'" style="height:100px; top:0%; background-image:url('<%= LogoPath %>'); background-size: 100% 100%; background-repeat:no-repeat">
123
Not easy to fix... if you set something absolutely, like you logo there, you break it out of the document flow. Hence, the rest of the page won't care where it is and cannot place itself next to it. It will just be under or over it.
You could detect the position of the logo with javascript and place the other one next to it if it too is aboslute.
I THINK you want to set the logo to position: fixed instead, and add margin-top to the body, so that it always starts where the logo ends. That way the logo would always be on top and follow you when you scroll, and the body wont be covered by the logo.
