Google Sheet Preview: is there any way?

I did shortly have a look, there is no specific class for docs iframe embeds but I did notice its max width was 100% but not the real width.. setting that to 100% made it wider and height is up to you

.post__regular .cooked {
    iframe {
      max-width: 100%;
      max-height: min(1000px, 200vh);
      width: 100%;
      height: 500px;
    }
}
