heres my css you can use as a base, just change the images, gifs, colors, and stuff so that it's not the exact same :3

.logo {
font-size: 0px;
}

.logo::after {
content: "add ur custom message here";
font-size: 23px;
color: white;
}
div#header {
color: white;
background-color: #ff0026;
background-image: url(insert link here);
background-position: 350 center;
text-align: center;
}

div#hSub {
background-color: #ff0026;
text-align:
