Alt text in responsive images. Posible?

Is it possible to attach to responsive images alt text without creating sample-image.jpg.meta.yaml?

{% for image in page.media.images %}
<img class="" {{ image.sizes('80vw').html() }}>
{% endfor %}

combine

alt="{{ page.parent.title }} | {{ page.title }}"

Thanks.

Mhm, maybe like this?

{% for image in page.media.images %}
   {{ image.sizes('80vw').html(page.parent.title, page.title, 'myClassName') }}
{% endfor %}

The html() function, outputs the image tag and you can add the alt and title tag. Never tried with responsive images though, but see here:

Thank you very much, everything works!
