CSS has the ability to override the height and width of images

<img src="img_beach.jpg" alt="Beach" width="800" height="600">

In my HTML body tag, the line above is what I have. However, the specified height and width are being replaced by the values set for the image in the stylesheet.

What could be causing this to occur?

Answer №1

As you delve deeper into styling the image element, consider the width and height attributes. These attributes inform the browser of the necessary space needed to display images when the page is first loaded.

Remember: It's best practice to specify both height and width attributes for images. By setting these values, the browser reserves the appropriate space for the image during loading. Without them, the browser won't know how much space to allocate, leading to changes in the page layout as images load.

Answer №2

To customize the appearance of images on your website, consider utilizing inline styles to override any existing CSS rules or targeting specific CSS selectors in your HTML code.

<img src="img_forest.jpg" alt="Forest" style='width:600px !important; height:400px !important;'>

Answer №3

When looking at the code, note that width="600" is considered an attribute, whereas width:100px is classified as a property. During the rendering process, these attributes are transformed into their corresponding styles and positioned at the start of the style sheet.

Answer №4

The reason for this is that the width and height attributes define the inherent width and height of the image.

By default, the CSS properties width and height have an initial value of auto. As images are considered replaced elements, they will use their intrinsic sizes (§10.3.2 and §10.6.2).

However, you can override this behavior by specifying a different size in your style declaration, which will then be applied to the image.

If you want to prevent overriding, you can add inline styles with the important flag:

<img src="img_forest.jpg" alt="Forest" width="600" height="400"
     style="height: auto !important; width="auto"!important" />

img {
  height: 100px;
  width: 500px;
}
<img src="/favicon.ico" alt="Forest" width="16" height="16"
     style="height: auto !important; width: auto !important" />
