Img coding in HTML is a fundamental skill that every web developer should master. It's used to add images to a website, which can enhance the user experience and make your website more visually appealing.

To add an image to your website, you need to use the img tag, which is a self-closing tag, meaning it doesn't need a closing tag. This is in contrast to other HTML tags, such as the paragraph tag, which does need a closing tag.

The src attribute is used to specify the location of the image file, which can be a local file or a URL from another website. The alt attribute is used to provide a text description of the image, which is useful for users who are visually impaired or have images turned off in their browser.

Image Display

Displaying an image in HTML is straightforward. It's done using the img tag, which stands for image.

The img tag has several attributes, but two are particularly important: src and alt. The src attribute is the location of the image, similar to links and can be absolute or relative. The alt attribute is a simple description of what the image is.

Here are some uses for the alt attribute:

  • Screen readers will read the alt text as opposed to displaying the image.
  • If there is an error loading the image for some reason then the alt text will be displayed instead.
  • Search engines will use the alt text to help index images.

By default, images will display at their actual size, but we can modify that with the width and height attributes.

Displaying

Displaying an image is a straightforward process that involves using the img tag. The img tag is a standard way to include images in your webpage.

The img tag has several attributes, but two of the most important ones are src and alt. The src attribute stands for source and specifies the location of the image, which can be an absolute or relative URL.

The alt attribute stands for Alternate Text and provides a simple description of what the image is. This description is useful in several ways.

Screen readers, which help people with vision impairment, will read the alt text instead of displaying the image. This is especially helpful for people who rely on assistive technology to navigate the web.

If there's an error loading the image, the alt text will be displayed instead, which can be a nice fallback. This is also a good practice for search engines, which will use the alt text to help index images.

Here are some key points about the img tag:

  • src attribute: specifies the location of the image
  • alt attribute: provides a description of the image
  • alt text is used by screen readers, displayed if image fails to load, and indexed by search engines

Display Size

Displaying images in the right size is crucial for a visually appealing and user-friendly experience. By default, images will display at their actual size.

Images can be modified to fit different dimensions, and we have two attributes to help with that: width and height.

Image Best Practices

To ensure your images load quickly and are accessible to all users, use a descriptive alt attribute to provide a meaningful description of the image. This helps users with screen readers understand the content of the image.

The alt attribute should provide a clear and concise description of the image, not just a file name or a generic phrase like "image."

Specify the image dimensions by providing the width and height attributes, which can help improve the page rendering speed by reducing layout "reflow" as images load.

Optimizing image files is essential for fast load times, and this can be achieved by compressing the images and using appropriate file formats, such as JPEG for photographs and PNG for graphics with transparency.

Image File Types

Choosing the right image file type can make a big difference in the quality and size of your images. The three main file types used in web pages are .jpg, .png, and .gif.

.jpg is ideal for photos and realistic images, and it's great for compressing large images without sacrificing too much quality. You can see this in action with a .jpg image that's 268 KiB at 100% quality, but only 53 KiB at 70% quality.

.png is ideal for images with a lot of solid colors, like charts and comics. It also supports transparency, which .jpg doesn't. This makes .png a great choice for images with text or shapes that need to be transparent.

Here are the main file types used in web pages, summarized:

  • .jpg - Ideal for photos and realistic images
  • .png - Ideal for images with solid colors and transparency
  • .gif - Similar to .png, but slightly older and less preferred

As you can see, .png is a more compact file type than .jpg, especially when used at lower quality levels. For example, a .png image at 100% quality is only 17 KiB, compared to a .jpg image that's 268 KiB.

Image Responsive Design

If your website needs to be displayed on multiple sized screens, you may find that your images are too large for some devices. This is particularly true if you use the width and height attributes to set the dimensions of a large image.

There are two main ways to deal with this situation.

Using responsive design can help, as it allows your website to adapt to different screen sizes. This is especially useful for websites that need to be displayed on mobiles, tablets, desktops, and laptops.

You can use the width and height attributes to set the dimensions of an image, but this can lead to large images that are not suitable for smaller screens.

Responsive design can be achieved by using relative units, such as percentages, to set the dimensions of images. This will allow your images to scale down on smaller screens.

Image Styling

Image Styling is a crucial aspect of HTML img coding. By default, every picture has a border around it.

You can change the thickness of the border using the border attribute. A thickness of “0” means that there will be no border around the picture.

To decorate an image, you can use the border property, as shown in the example of setting the style of an image. This can add a professional touch to your web pages.

The border attribute can be used to add a decorative border to an image, making it stand out on your web page.
