How to float one image over another

In many situations you may want to position one image on top of another image. There are many ways to achieve this using HTML and CSS. You can find here some easiest methods from this lesson.

The following HTML-CSS code placing one image on top of another by create a relative div that is placed in the flow of the page. Then place the background image first as relative so that the div knows how big it should be. Next is to place the overlay image as absolutes relative to the upper left of the first image.

HTML-CSS Source Code

position: relative — In relative position method , you can position the element relative to its normal position. In this case you should use left or right and top or bottom to move the element relative to its container.

position: absolute — When we position an element as Absolute , that element is is completely removed from the document`s normal flow. In Absolute position, the position is set through some combination of left, right, top and bottom properties.

Next approach is using z-index to put an image on top of another image.

HTML-CSS Source Code

z-index

While overlapping CSS elements, when using absolute and relative position, the default behavior is to have the first elements underneath later ones. In these cases we can control layering of positioned elements by using the z-index property . When using the z-index property you can specify which of the boxes appears on top the other one.

How to Position One Image on Top of Another in HTML/CSS

Sometimes, you may need to position one image on top of another. This can be easily done with HTML and CSS. For that, you can use the CSS position and z-index properties.

First, we are going to show an example where we use the position property.

Create HTML

The first image will be the background image and the second will overlay it.

div class="parent"> img class="image1" src="/uploads/media/default/0001/01/25acddb3da54207bc6beb5838f65f022feaa81d7.jpeg" /> img class="image2" src="/uploads/media/default/0001/01/25acddb3da54207bc6beb5838f65f022feaa81d7.jpeg" /> div>

Add CSS

• Add a relative div placed in the flow of the page.
• Set the background image as relative so as the div knows how big it must be.
• Set the overlay as absolute, which will be relative to the upper-left edge of the container div.

We place the background image at the beginning of the container, and then we will set the overlay image to start from 30 pixels after the background.

.parent < position: relative; top: 0; left: 0; > .image1 < position: relative; top: 0; left: 0; border: 1px solid #000000; > .image2 < position: absolute; top: 30px; left: 30px; border: 1px solid #000000; >

Let’s see the full example.

Example of positioning an image on top of another using the position property:

html> html> head> title>Title of the document title> style> .parent < position: relative; top: 0; left: 0; > .image1 < position: relative; top: 0; left: 0; border: 1px solid #000000; > .image2 < position: absolute; top: 30px; left: 30px; border: 1px solid #000000; > style> head> body> div class="parent"> img class="image1" src="/uploads/media/default/0001/01/25acddb3da54207bc6beb5838f65f022feaa81d7.jpeg" /> img class="image2" src="/uploads/media/default/0001/01/25acddb3da54207bc6beb5838f65f022feaa81d7.jpeg" /> div> body> html>

Result

In this example, we used both the relative and absolute values of the position property. The relative value places an element relative to its normal position. The absolute value removes elements from the document flow, and elements are positioned relative to its parent element’s position.

Now, let’s see an example where we use both the position and z-index properties.

Example of positioning an image on top of another using the position and z-index properties:

The z-index is a CSS property to determine which element to overlay and which element to be in the background. The idea is to imagine a z-axis perpendicular to the screen. The higher the z-index of an element, the element will be shown nearer to the one viewing the page, thus overlaying the other elements with a lower z-index.

html> html> head> title>Title of the document title> style> .image1 < position: absolute; top: 10px; left: 10px; border: 1px solid #000000; z-index: 1; > .image2 < position: absolute; top: 25px; left: 25px; border: 1px solid #000000; z-index: 2; > style> head> body> img class="image1" src="/uploads/media/default/0001/01/25acddb3da54207bc6beb5838f65f022feaa81d7.jpeg" /> img class="image2" src="/uploads/media/default/0001/01/25acddb3da54207bc6beb5838f65f022feaa81d7.jpeg" /> body> html>

In the example mentioned above, we set the position to absolute for both elements. You can try the snippet yourself, and see that you can swap the overlaying and the background image easily by changing the z-index. By z-index you can set any element on top of another one, and not just images.

Image Modal (Advanced)

This is an example to demonstrate how CSS and JavaScript can work together.

First, use CSS to create a modal window (dialog box), and hide it by default.

Then, use a JavaScript to show the modal window and to display the image inside the modal, when a user clicks on the image:

Example

// Get the modal
var modal = document.getElementById(‘myModal’);

// Get the image and insert it inside the modal — use its «alt» text as a caption
var img = document.getElementById(‘myImg’);
var modalImg = document.getElementById(«img01»);
var captionText = document.getElementById(«caption»);
img.onclick = function() modal.style.display = «block»;
modalImg.src = this.src;
captionText.innerHTML = this.alt;
>

// Get the element that closes the modal
var span = document.getElementsByClassName(«close»)[0];

// When the user clicks on (x), close the modal
span.onclick = function() <
modal.style.display = «none»;
>

How to position an image anywhere with CSS

We can position an image anywhere inside a parent container. We usually align an image horizontally to left, center and right by using different CSS tricks. But by using position:absolute , we can align an image both horizontally and vertically; not only to center or right but in any position- near top, bottom, left or right edge of a container.

Noted, in this way, not only image, we can also set position of other html elements like p , h , div and so on.

So no more ado. Let’s start to move on practical ground.

How position:absolute works to position an image

To make position:absolute work to position an image anywhere, do the followings:

• Take a container div .
• Style the div with position:relative .
• Style the div with width and height value. You can also set other property if you wish.
• Take img element inside the div .
• Style the img with position:absolute .
• To fix definite position of img ; style the image with top, bottom, left and right property. Noted, set value in any one of Top and Bottom property. Also set value in any one of Left and Right property.
• Image width and height value must be lower than that of div .
• Set other property:value with img if you wish.

Position 1: Align image near top-right

To keep things simple, we’re using inline CSS. First, let’s style the container div:

Now set the image attributes with style:

Position 2: Align image near bottom-right

Position 3: Align image near bottom-left

Position 4: Align image near top-left

Position 5: Align image on center horizontally and vertically

Hope you can position the image in any other places beyond the shown examples by using the defined rules.

Comment, please!!
