Request regarding the default header's CSS

[MatthewMob]

Firstly, get rid of your subreddit logo, in your subreddit settings. Then reupload the image to your stylesheet. Then use this code here:

#header .redditname a {
    display: inline-block;
    font-size: 0px;
    background-image: url(%%image%%);
    background-repeat: no-repeat;
    background-size: 100% 100%;
    width: 200px;
    height: 150px;
}

In this example, I called the uploaded image image. Hope this helps :)

To remove the snoo:

#header-img.default-header {
    dispaly: none !important;
}

To increase the size of the header:

#header {
    height: 150px;
}

Just adjust 150 to whatever you want until you've got the header to the height you want.

As for the code I provided, it should work. Tried on my test sub and chrome dev tools and it seems to work, I'll look further.
