Comment by Daniel Cobo on "Tips For Writing Good Alt Text In HTML"

🙅‍♂️Just say no to this:

Another alternative is to leave the alt text empty. Most screen readers will skip reading an image with empty alt text.

There is no alternative, either it's content (and deserves alt) or style (and should be in CSS).

Although I do like that you included what happens when there's no alt text.

Hi Daniel,

Thank you for the feedback 😊

I agree that images should have alt text. And whenever images are presented for pure decoration purposes, the best way is to use CSS to add those images.

However, when using CSS is not an option, another alternative is to have null alt text. That means, we still provide the alt attribute, but with empty text to be ignored by the Assistive Technology such as screen readers. This technique still complies with WCAG 2.1.

Thank you for reading my post 😊

Ayu Adiati I get that realistically there may be some reason why no alt is there and the dev has no control over it (perhaps it's a CMS and the user skips to add a description..)

I believe in that case the dev should advocate to make it a mandatory field and explain the importance to the end-user

As even that may not be possible in some organisations I do appreciate that you consider what may be called a progressive enhancement approach to accessibility

Good advice, Daniel Cobo. Thank you 🙂
