Here is the screenshot.

I can't debug in mobile browser and can't see what happen, whereas PC's browser look good no problem with mobile size when I'm debugging.
Browser: Safari & Edge in iOS 14.4.2

@bennyxguo I have just comeback for writing blog, so I have come to debug it in detail on my iPhone. I found out that the fadeIn js cause flash for all over iPhone's browser, from Edge to Safari, Opera, Chrome.

 <div class="article-cover animated fadeIn" style="
            animation-delay: 600ms;
            animation-duration: 1.2s;
            background-image: 
                radial-gradient(ellipse closest-side, rgba(0, 0, 0, 0.65), #100e17),
                url(/img/cover.jpg) ">
</div>

The version cause bug is animate 3.7.2, so I tried updating to newest 4.1.1 and it is fixed well. So just open head.js, replace

cdnjs.cloudflare.com/ajax/libs/animate.css/3.7.2/animate.min.css

To

cdnjs.cloudflare.com/ajax/libs/animate.css/4.1.1/animate.min.css

I deployed fix on my blog: https://nguyenluu.dev, you could compare with yours current
