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.

Styling Images in CSS

When it comes to enhancing the beauty of the web design we often think of adding images to our website. However, just adding images is not enough, therefore, you need to style them in various ways to make them look more appealing. CSS provides plenty of properties that you can use to add styling to images.

This post enlightens on how to style images in CSS. In this guide, you will go through the following:

1. How to make circled images
2. How to make rounded corner images
3. How to make responsive images
4. How to center images
5. How to make transparent images
6. How to place text on images
7. How to add filter to images
8. How to make hover overlay on images
9. How to flip images

How to make circled images

For the purpose of making your images appear as circles, use the CSS border-radius property. Below we have presented you with an example of a circled image.

Here we have simply added an image in the src attribute of the tag.

Setting the border-radius to 50% we are making the image a circle. You can change the value if you wish to make it an oval or less rounded.

The image was circled successfully.

How to make rounded corner images

The CSS border-radius property can also be used to make the corner of images rounded, here is how you do it.

Here we are giving the border-radius value in pixels to make the corners rounded.

The corners of the image have been rounded.

How to make responsive images

Images that are responsive adjust their size according to the browser window. The below-mentioned example demonstrates how to do it.

In the above code, we have simply added an image.

To make the image responsive, set the max-width to 100% and height to auto.

The image is changing its width according to the size of the browser window.

How to center images

To place an image in the center, display it as a block-level element and set its margins to auto. Consider the example below.

To center an image we are simply displaying it as a block-level element and setting its right and left margins to auto.

The image has been center aligned.

How to make transparent images

If you wish to make your images transparent then use the CSS opacity property. The lesser the value of the opacity property, the more the transparency of the image.

In the above code, the opacity of the image was set to 0.3.

The image was made transparent successfully.

How to place text on images

Use the CSS position property to place text on certain positions on the images. The various positions that you can place the text on the image are as follows.

Here we have demonstrated with the help of an example.

In the above code, we have created a div container and placed the image and another div container inside it.

.div {
position : relative ;
}
.topleft {
position : absolute ;
top : 5px ;
left : 5px ;
font-size : 20px ;
font-style : italic ;
}
img {
width : 400px ;
opacity : 0.5 ;
}

The first div has been given a relative position so that the second div that holds the text can be placed inside it. Using the topleft class we are assigning the second div an absolute position and giving it some length from top and left, moreover, giving certain font size and style to the text.

The text has been added on the image at the top left position.

How to add filters to images

For the purpose of adding filter to images such as blurriness or saturation, use the filter property. Consult the example below:

Here we are using the invert() method on the filter property to add visual effects to the image.

Visual effects were added successfully to the image.

Some other methods that you can use on the filter property to add various visual effects are:

• blur(),
• contrast(),
• brightness(),
• grayscale(),
• saturate(),
• opacity(), etc.

How to flip images

Flipping an image when the user brings the mouse over it can be an interesting thing to do. In order to do this, use the CSS transform property.

Here we are flipping the image along the Y-axis using the scaleY() method of transform property.

The image was flipped across the y-axis.

Conclusion

Styling images that appear on your website is highly important and this can be done using various CSS properties. Multiple things that you can do to style your images is that make them a circle, make their corners rounded, or make them a thumbnail. Moreover, you can make your images responsive, or add text or certain visual effects on them. In this post, we have shown many ways in which you can style your images using CSS, along with relevant examples.

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.
