I updated the code to be more clear on where you put the flags

1. you choose the flag you want from here https://toyhou.se/16962387.html-pride-flags/16990719.code
   
   each flag is one line of the code (as far as I'm aware I haven't looked at em all lol) like this
   <div class="rounded d-inline-block" style="background-image:linear-gradient(#ec728f,#ec728f 16.7%,#e69ab0 16.7%,#e69ab0 33.4%,#c4c4c4 33.3%,#c4c4c4 50.1%,#76d5ea 50.1%,#76d5ea 66.8%,#3bc3ec 66.8%,#3bc3ec 83.5%,#f2e886 83.5%);line-height:20px;width:26px;"> </div>
2. then paste them into my code after ---> and before <!--- END OF FLAGS --->

it should look like this
