style="width: 45px !important" in Django not works

I'm using django to make a web site.

When I render<img src="{{ board.writer.profile_photo.url }}" width="45px" height="45px" style="width: 45px !important; border-radius: 50%;"/> this html, the style="width: 45px;" part changes into style="width: 100%. I have no idea why this happens. screenshot from chrome devtool

I'm using python3.8, django 4.0.1 on Ubuntu 20.04.
