I would like to place a smaller image with a transparent background in front of a header image in WordPress. The theme I am currently using allows me to set own css styles but I have no clue how to achieve my goal.
Has anybody already worked on this?
Thanks a ton,

Here is an example how to place an image in front of another image. I placed a PNG of a bee inside a banner image.
HTML
<div id="container">
<img id="banner" src="https://www.mortcap.com/images/sample_report_banner.png">
<img id="bee" src="https://orig00.deviantart.net/672c/f/2014/320/3/1/bee_png_stock_by_karahrobinson_art-d86m7bq.png">
</div>
CSS
#container {
position: relative;
}
#banner {
width: 600px;
}
#bee {
position: absolute;
z-index: 5;
top: 20px;
left: 20px;
width: 100px;
}
When we set position: absolute, that element will always be position relative to the nearest parent with position: relative (or absolute). And then you can refine the position of the absolutely positioned element using top, bottom, left, right css properties.

I have a full-width cover image. Inside of that, I have a bootstrap container class with an absolute positioned image that sits on top of the cover image. What I would like to to do is have that image positioned to the right-hand side of the container only.
Here is my code:
<div id="header">
<div class="container">
<img src="header-icon.png" class="header-icon" />
</div>
</div>
#header {
background-image: url('cover.jpg');
background-size: cover;
height: 300px;
position: relative;
.header-icon {
position: absolute;
bottom: 0;
}
}
Of course, when I add right: 0 to the header-icon, it aligns outside the container. I could, of course, create media queries and try and position the icon based on screen size, but I'm wondering if a better way to do it exists.
I have also tried to make the icon relative to the container, but this seems to break what I am trying to achieve.
I'm not 100% sure what you are trying to achieve, but it sounds like you want right: 0 to align the image to the right of the container and not the header.
position: absolute will position an element absolutely according to the first parent element that is not positioned statically. Right now, you have #header with relative position, but .container still has static position. Therefore, you want to apply position: relative to the container:
#header .container {
position: relative;
}
Also, the code you posted seems to be missing a </div>.
Is this what you are looking for jsfiddle, this is the code i added
#header .container {
position: relative;
height: 400px;
}
I have a little problem i was hopeing you guys could help with. I have create an empty white box on my frontimage. To do that i have to change the image to absolute. After this, the image is now out of alignment. To make it easier to understand, there are two images i want to show you, so you can see the problem.
Image when it is set to Relative:
Its the water image in top.. here you see that it is perfect align (left and right side) with the aque color boxes under.
Image when it is set to Absolute:
Somehow when i set the image to absolute, it gets bigger in the right side. I have read some earlier post that the parant should be set to relative.. I mean that I already have done that.
Code:
<div class="row">
<div class="col-sm-12 contentpage">
<img id="frontimage" src="~/images/index.jpg" />
<div class="col-lg-4">
<div class="bookingbox">
</div>
</div>
</div>
</div>
Css:
#frontimage{
z-index: 1;
position: absolute;
}
.contentpage {
height: 650px;
background-color: white;
position: absolute;
}
.bookingbox {
background-color: green;
position: absolute;
height: 450px;
width: 300px;
z-index: 2;
position: absolute;
top: 30px;
left: 30px;
}
img {
max-width: 100%;
}
Now it works.. take a look at the picture :D
Of course it's out of alignment!
When you set the image to absolute, it breaks off the flow of the page, and basically creates a new "layer" to be on. You can say it's "absolutely" off the page flow.
When you set the image to absolute, to position it correctly, make the parent of the image relative, then position and resize the image according to the origin of the parent.
Make sure to add another div so it fits inside it! winks
I have seen the layout similar to the image below used on some sites before and I really like the design but don't exactly know how to implement the overlapping image (Profile Image). I am using bootstrap if that helps. Any ideas?
Thanks!
I can see three ways to do this generally.
position: absolute
You could give the image or the image's wrapper the attribute of position:absolute and giving its container (in your example the green box) position:relative. Then you would apply top: -100px or whatever and a left attribute of left: 100px or whatever. This gives the effect of the image being out of flow, aligned to the left and offset by 100px, and 100px offset from the top of the green container. The disadvantage of this approach would be that any body content in your green container could appear under the image.
position: relative
This is the same approach as the first one with the exception of how the image flows in the document. Instead of giving the image position:absolute, you would give it position:relative. Relative works differently from absolute. instead of being x and y coordinates of the parent container, it's just shifted by however much you give as a value for top and left. So in this case, you would apply top:-100px and just leave the other directional values as default. this would shift your element by that amount but also leave its original spot in the document flow. As such you end up with a gap below the image that other content will flow around.
negative margin
I honestly would prefer this method in your case. In this method, you can give the image a negative margin (e.g. margin-top:-100px). This will offset the image, collapse the area below the image, and it will still retain some of its flow in the document. This means that the content of the green container will flow around the image but only around the part that is still inside the container. It won't have a ghost area that content flows around like with relative positioning, but it also doesn't entirely take the image out of flow like absolute positioning. One thing to keep in mind, however, is that if you try to use overflow of any kind other than the initial value, it will cause undesirable effects to your image.
Demo
Here's a quick little demo demonstrating all three methods in a simple use case: http://jsfiddle.net/jmarikle/2w4wqfxs/1
The profile image can be set with position: absolute; top: 20px; left: 20px, or something like that to keep in from taking up space in the flow of the page.
make the html element that holds the header image "position:relative". Then put the header image and the profile image in that element. then make the profile image "position:absolute" and utilize "top: XXpx" depending on how far you want it from the top of the header element. Same for "left".
see fiddle here
<div class="header">
<img src="" alt="my image" class="floatdown">
this is my header, image could go here too
</div>
<div class="body">
this is my body content
</div>
.header {
position: relative;
width: 100%;
height: 150px;
border: 2px solid #000;
text-align: right;
}
.body {
position: relative;
width: 100%;
border: 2px solid #000;
height: 500px;
text-align: right;
}
img {
width: 90px;
height: 90px;
border: 2px solid #ddd;
}
.floatdown {
position: absolute;
top: 100px;
left: 20px;
}
You can use the float property on your profile image to take it out of the "flow" of the document, and play with the margins to place it properly.
CSS :
#profile-image{
width: 100px;
height: 100px;
float: left;
margin: 100px;
}
The marginis used to push it down and place it properly.
You can see an example of this in a Fiddle : http://jsfiddle.net/y706d77a/
I wouldn't recommand using position: absolute as you can get very strange results with different resolutions. I would only use that as a last resort.
This can be done many ways.
Anytime you see something like that on the web you can just use your inspector or firebug and see how they are doing it to get some ideas.
It wouldn't hurt to do some research on the web about CSS positioning.

Another great site.

I just finished it.
Here is a codepen link:
http://codepen.io/anon/pen/zxYrxE
HTML:
<div class="main-container">
<div class="header">
<p>This is the header div</p>
</div>
<div class="profile">
<p>Profile</p>
</div>
<div class="content">
<p>Some dummy content div</p>
</div>
</div>
CSS is to big to be pasted here, so just open the link.
Put the profile image in the header, make the position: absolute; and the image position: relative;, and give it a negative bottom value that's half the height of the image, and set left to position it horizontally to taste.
HTML
<header>
<img class="profile">
</header>
<div>Content</div>
CSS
header, div{
min-height: 110px;
background: darkgray;
}
header{
position: relative;
background: gray;
}
img{
position: absolute;
bottom: -50px;
left: 100px;
}

I'm trying to build a website header that is semi transparent, and contains a semi transparent image that hangs outside the of the header div, like in the image linked below.
Because of overlapping opacities, I can't simply put a semi transparent image in to a semi transparent div and add a negative margin to the image. The best I could come up with was taking the height of the header image, and cutting that bit of the logo image, like in image attached. However that's not ideal, as doesn't play nice responsively etc etc.
Any ideas of how I might achieve this look?
Thanks in advance.
If you know the height of your menu then you can place both the logo and the menu inside of a container. Then position the logo with the top value equalling the height of the menu.
.header-bg {
background: rgba(225, 225, 225, 0.5);
position: relative;
height: 60px;
}
.header-bg .logo {
width: 90px;
height: 90px;
background: rgba(225, 225, 225, 0.5);
position: absolute;
top: 60px;
left: 10%;
}

Hope that helps in some way.
This is an interesting problem and there are a couple ways to solve it; two come immediately to my mind.
The first is your method; carefully position things so that you don't have multiple translucent sections overlapping. This wouldn't be too difficult; if you go with this method I would recommend breaking the header into sections left and right of the image and using absolute positioning.
The second and easier way is to create a version of the picture with the semi-transparent white overlay you desire already applied. Then you can use that as the background for the menu and image. The only tricky thing here is you have to make sure the images line up by either using fixed positioning or calculated pixel offsets. This approach has been around for a long time and you can see any early example (2001-ish) of it here.
My take on it is to create a :before pseudo-element. It has its problems, including what if the logo changes in size at some point, but overall it works.
HTML
<a class="logo" href="#">
<img src="https://example.com/logo.png" />
</a>
CSS
nav a.logo {
position: relative;
...
display: inline-block;
line-height: 0.0001em;
font-size: 0.0001em;
}
nav a.logo img {
position: relative; /* for z-index issues. giving the image a relative
position automatically will place it above the
absolutely positioned :before element. This is
because the before element is rendered before the
image */
}
nav a.logo:before {
content: '';
position: absolute;
display: block;
width: 100%;
height: 71px;
bottom: 0;
left: 0;
background: rgba(0,0,0,0.4);
...
}

You can use rgba color format for background of both the .logo and the header to achieve your desired effect. However, you have to give position: absolute; to your .logo class because it needs to come right below the header. If you put your .logo on top of your header, then colors will overlap and won't look right. So, it needs to starts at the bottom of the header.
The header should have position: relative; so that your .logo is positioned relatively to the header. This way, you don't even need to know the height of your header because when you define top position of your .logo, you can simply use top: 100% so that it always starts right below your header. You don't have to hardcode that top value.
Now, you need to shift your actual logo (image) inside your .logo on top because its appearing below the header right now. For that you can simply push the image by giving it negative margin-top value.
SEE THE DEMO
The code would look like this:
HTML
<header>
<h1 class="logo">
<img src="/image/path" alt="logo">
</h1>
</header>
CSS
header {
background: rgba(255,255,255, 0.7);
position: relative;
}
.logo {
position: absolute;
top: 100%;
background: rgba(255,255,255, 0.7);
}
.logo img {
margin-top: -50px;
}
How do I put a transparent png image over a DIV without it affect anything else in the HTML document? I would do position absolute because it takes it out of the "normal flow of the document" but I have the whole website centered using "margin-left: auto;" and "margin-right: auto;"
if you apply position: relative to the div you want to cover then position: absolute on the image will be calculated relative to the covered div rather than the whole page, if it is a child element. i.e.
<div id="tobecoverd">
<p>your content...</p>
<img src="./img/transparent.png" class="cover" />
</div>
div#tobecovered{
position: relative;
}
div#tobecovered img.cover{
position: absolute;
/* position in top left of #tobecovered */
top: 0; /* top of #tobecovered */
left: 0; /* left of #tobecovered */
}
Other solution is to use after like this:
.image:after{
content: "";
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
background: url(https://i.imgur.com/DDdKwlk.png) no-repeat 0 0;
background-size: cover;
}
:)
I would say float is a good way to do this by not block other things , with absolute , some thing will hide under it or show above it base on the z-index.
This is a good tutorial on css positioning , take a look , you might found what you looking for
I think position:absolute is more appropriate for normal usages as it follows the scroll.
Here's how it works. The example shows a transparent image absolutely positioned over another image, creating a mask.
Check working example at http://jsfiddle.net/39VG9/1/
You be able to use this css in a class_name in React js (in html is class="class_name") to show a div as a pop up (bring up) or send back.
<div classname="class_name">
...
</div>
.class_name{
position: absolute;
/**Put div hide*/
/**z-index: -9;*//
/**Put as pop up*/
/**z-index: 9;*//
}
