How do you add an image in css

HTML Images

Images can improve the design and the appearance of a web page.

HTML Images Syntax

The HTML tag is used to embed an image in a web page.

Images are not technically inserted into a web page; images are linked to web pages. The tag creates a holding space for the referenced image.

The tag is empty, it contains attributes only, and does not have a closing tag.

The tag has two required attributes:

Syntax

The src Attribute

The required src attribute specifies the path (URL) to the image.

Note: When a web page loads, it is the browser, at that moment, that gets the image from a web server and inserts it into the page. Therefore, make sure that the image actually stays in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon and the alt text are shown if the browser cannot find the image.

Example

The alt Attribute

The required alt attribute provides an alternate text for an image, if the user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).

The value of the alt attribute should describe the image:

Example

If a browser cannot find an image, it will display the value of the alt attribute:

Example

Tip: A screen reader is a software program that reads the HTML code, and allows the user to «listen» to the content. Screen readers are useful for people who are visually impaired or learning disabled.

Image Size — Width and Height

You can use the style attribute to specify the width and height of an image.

Example

Alternatively, you can use the width and height attributes:

Example

The width and height attributes always define the width and height of the image in pixels.

Note: Always specify the width and height of an image. If width and height are not specified, the web page might flicker while the image loads.

Width and Height, or Style?

The width , height , and style attributes are all valid in HTML.

However, we suggest using the style attribute. It prevents styles sheets from changing the size of images:

Example

Images in Another Folder

If you have your images in a sub-folder, you must include the folder name in the src attribute:

Example

Images on Another Server/Website

Some web sites point to an image on another server.

To point to an image on another server, you must specify an absolute (full) URL in the src attribute:

Example

Notes on external images: External images might be under copyright. If you do not get permission to use it, you may be in violation of copyright laws. In addition, you cannot control external images; they can suddenly be removed or changed.

Animated Images

HTML allows animated GIFs:

Example

Image as a Link

To use an image as a link, put the tag inside the tag:

Example

Image Floating

Use the CSS float property to let the image float to the right or to the left of a text:

Example

The image will float to the right of the text.

The image will float to the left of the text.

Tip: To learn more about CSS Float, read our CSS Float Tutorial.

Common Image Formats

Here are the most common image file types, which are supported in all browsers (Chrome, Edge, Firefox, Safari, Opera):

Abbreviation	File Format	File Extension
APNG	Animated Portable Network Graphics	.apng
GIF	Graphics Interchange Format	.gif
ICO	Microsoft Icon	.ico, .cur
JPEG	Joint Photographic Expert Group image	.jpg, .jpeg, .jfif, .pjpeg, .pjp
PNG	Portable Network Graphics	.png
SVG	Scalable Vector Graphics	.svg

Chapter Summary

• Use the HTML element to define an image
• Use the HTML src attribute to define the URL of the image
• Use the HTML alt attribute to define an alternate text for an image, if it cannot be displayed
• Use the HTML width and height attributes or the CSS width and height properties to define the size of the image
• Use the CSS float property to let the image float to the left or to the right

Note: Loading large images takes time, and can slow down your web page. Use images carefully.

CSS Image Styling: How to Add, Center, and Resize Images with CSS

HTML, CSS, and Javascript are three essential computer languages in web development that influence the website’s aesthetics. This is general knowledge, and almost everyone knows about it.

If HTML is about giving the website’s framework, then CSS is the language that concentrates on adding features to the underlying framework, allowing the website to become more visually appealing.

This is why, through CSS, we are going to look at the different ways we can add, style, and align images on a website.

How to Add an Image in CSS?

Before we look into these topics, we have to get the facts straight.

First, the job of CSS is to provide an enhancing design to the structure of the website. So we’ll be adding the image through HTML and not CSS.

So to add images, we use the inline element. Through this HTML element, we will only be able to add the image, source, and link. Then with the help of CSS, we will mention the proportions and other needed styles of the image.

Before jumping into examples, let’s look at some properties which influence the shape, size, and other altercations of images:

• First, the border property is used to specify the image’s border.
• Next, the height property is used to specify the image’s height.
• Finally, the width property is used to specify the image’s width.

img src="https://tinyurl.com/dkxknyfv" alt="A black, brown, and white dog">

In the above example, we have used HTML to add images to the website and use CSS to set display options on how the website should appear.

How to Centre and Image in CSS?

Images can be easily centred with the help of left-margin and right-margin properties. Here is an example that vividly explains how we can centre images on a web page using CSS.

How to Resize an Image in CSS?

The issue with HTML is that when images are added, it usually takes up more pixels of the webpage. Therefore, for a responsive web design, the images on a website should be able to resize on their own depending on the screen size. This, fortunately, can be achieved through the following properties:

The max-width and max-height properties will automatically resize the images depending on the screen size displayed on the site.

The object-fit property is another property used to resize the website’s image automatically. The object-fit property will resize the image using the contain value according to the screen requirements.

How to Align an Image in CSS?

Whether it is left alignment or right alignment, or even centre alignment, it is possible, and images can be aligned within a matter of seconds in CSS through the text-align and float properties:

Using the text-align property can easily align images on a website. With the text-align property and values such as left, centre, and right, one can appropriately align images on a website.

The float property is yet another property used in aligning images on a website.

How to Add a Background Image in CSS?

A visually enhanced website sets beautiful minimalistic images as background images. Fortunately, CSS has the background-image property to set beautiful images as background images for websites.

Conclusion

Adding, altering, and aligning images to change a plain-looking website into a visually appealing one takes only a few minutes with CSS. We hope you learned something new about front-end development to improve the appearance of websites.

CSS Background Image – How to Add an Image URL to Your Div

Amy Haddad

Say you want to put an image or two on a webpage. One way is to use the background-image CSS property.

This property applies one or more background images to an element, like a , as the documentation explains. Use it for aesthetic reasons, such as adding a textured background to your webpage.

Add an Image

It’s easy to add an image using the background-image property. Just provide the path to the image in the url() value.

The image path can be a URL, as shown in the example below:

Or it can be a local path. Here’s an example:

Add Multiple Images

You can apply multiple images to the background-image property.

That’s a lot of code. Let’s break it down.

Separate each image url() value with a comma.

background-image: url("https://amymhaddad.s3.amazonaws.com/morocco-blue.png"), url("https://amymhaddad.s3.amazonaws.com/oriental-tiles.png"); 

Now position and enhance your images by applying additional properties.

background-repeat: no-repeat, no-repeat; background-position: right, left; 

There are several sub-properties you can add to your background images, such as background-repeat and background-position , which we used in the above example. You can even add gradients to a background image.

See what it looks like when we put everything together.

Order Matters

The order that you list your images in matters because of the stacking order. That means the first image listed is nearest to the user, according to the documentation. Then, the next one, and the next, and so on.

We’ve listed two images in the code above. The first image (morocco-blue.png) will be in front of the second (oriental-tiles.png). Both images are the same size and lack opacity, so we only see the first image.

But if we move the second image (oriental-tiles.png) over to the right by 200 pixels, then you can see part of it (the rest remains hidden).

Here’s what it looks like when we put everything together.

When Should You Use Background Image?

There’s a lot to like about the background-image property. But there’s a drawback.

The image may not be accessible to all users, the documentation points out, like those who use screen readers.

That’s because you can’t add textual information to the background-image property. As a result, the image will be missed by screen readers.

Use the background-image property only when you need to add some decoration to your page. Otherwise, use the HTML element if an image has meaning or purpose, as the documentation notes.

That way, you can add text to an image element, using the alt attribute, which describes the image. The provided text will be picked up by screen readers.

Think of it this way: background-image is a CSS property, and CSS focuses on presentation or style; HTML focuses on semantics or meaning.

When it comes to images, you’ve got options. If an image is needed for decoration, then the background-image property may be a good choice for you.
