A proper alt will be helpful to improve SEO.

[Fireentity]

In this case, these are only graphical elements that should be ignored by screen readers. I looked into best practices for such situations and found that it’s better to use an empty alt attribute.

I’ve read https://www.w3.org/WAI/WCAG21/Techniques/html/H67, which recommends using an empty alt attribute for purely decorative images so that they’re ignored by screen readers.
That’s why I applied this approach here.

If you have another suggestion or see a better solution, I’ll be happy to implement it.
