You can adjust the src attribute of an image using CSS by targeting the img element with a class or ID. This is useful for styling and positioning images without having to change the HTML code.

For example, if you have an image with a class of "hero-image", you can use CSS to adjust its src attribute by setting the background image of the parent element. As shown in the article, this can be done by setting the background-image property to the desired image URL.

This approach is particularly useful when you need to change the image dynamically, such as in a responsive design. By using CSS to adjust the image src, you can avoid having to update the HTML code every time the image changes.

Resizing Images

Resizing images in HTML can be done in a few ways. If you still want to resize your images in HTML, there are several methods to do so.

You can resize an image while maintaining its aspect ratio by setting the width to 100%. This is the easiest way to automatically resize an image.

The default height setting is "auto", which scales the height automatically based on the width. This means the image will be resized proportionally.

The "max-content" setting is optional and limits an image's maximum size to the original width. This prevents the resized image from becoming blurry and over-stretched.

In my experience, setting the width to 100% and using the "auto" height setting is a good starting point for resizing images in HTML.

Image Styling

Image Styling is a key aspect of adjusting img src with CSS. You can use CSS to change the appearance of an image without altering its source.

By applying styles like border-radius, box-shadow, and filter, you can give your images a unique look. For example, adding a box-shadow to an image can create a subtle depth effect.

Using CSS to style images can also help with accessibility by providing alternative text for visually impaired users. This is especially important when using images as part of a website's content.

Image Positioning

Image Positioning is a crucial aspect of image styling, allowing you to control where your images appear on the page.

You can define the position of your image as fixed, relative, static, sticky, or absolute, which gives you a lot of flexibility in terms of placement.

To set the position of your image, you'll need to use one of the following properties: top, bottom, left, or right.

These properties can support a range of values, including inherit, initial, %, length, and auto, which determine the effect of the property on the position.

You can think of it like placing a picture on a wall - you need to decide where it will be positioned, and how it will be aligned.

Creating Image File Borders

Creating Image File Borders is a great way to add some visual flair to your images. We can create borders, such as rounded corners, for our image using CSS.

To create a border for an image, we use the border property. This property allows us to set the width, color, and style of the border.

The border style property is particularly useful for setting different styles for images. For example, we can use it to create rounded images.

To achieve rounded images, we can use the following code:

Image Effects

Image effects can be achieved using CSS image filters. The standard syntax includes filters like sepia(), saturate(), opacity(), Invert(), hue-rotate(), grayscale(), drop-shadow(), and contrast().

These filters can be used to modify an image's appearance, making it easier to create visually appealing effects. For example, applying a sepia filter can give an image a warm, vintage look.

Developers can also use CSS queries to create image galleries, making it simple to display multiple images with different effects.

Here are some examples of CSS image filters:

  • sepia()
  • saturate()
  • opacity()
  • Invert()
  • hue-rotate()
  • grayscale()
  • drop-shadow()
  • contrast()

Scaling and Cropping Images with CSS

Maintaining the aspect ratio when resizing images is crucial for preserving image quality. To do this, you can add a style tag to the HTML header with the following code:

You can also set the width to 100% and the height to "auto" for automatic scaling. This approach is the easiest way to resize an image while maintaining its aspect ratio.

The "max-content" setting can be used to limit an image's maximum size to its original width. This is useful for preventing the resized image from becoming blurry and over-stretched.

In my experience, using the "max-content" setting can make a big difference in image quality.
