A few tweaks you can add to your forum.

If you ask me, the post created by @winteriscoming appears to be starting a bit of a customization revolution.

With Tracking & Analytics (premium sites only) you can customize your forum even more.

Make sure that all custom embeds are set to the below:

To remove the sidebar and widen the post area:

<style>
.qwUf2
{
display: none;
}
.app-desktop .FLyif
{
max-width: 100%;
}
._1wZij
{
max-width: 100%;
}
.app-desktop ._1NkaF
{
max-width: 100%;
}
</style>

To move the like button to the right:

<style>
._3jepg
{
padding-left: 700px;
display: content;
}
.GcHCJ
{
padding-left: 700px;
display: content;
}
</style>

To remove the blue outline when creating/editing a post or comment:

<style>
._1Fqrx :focus
{
outline: 0px !important;
-webkit-appearance: none;
box-shadow: none !important;
}
</style>

To change the selected text colour:

<style>
::selection
{
background: #003cff;
color: #ffffff;
}
</style>

To change your cursor:

<style>
body {

  cursor: crosshair;/* or whatever other icon you want. */

}
</style>

To change the scrollbar:

 <style>
 ::-webkit-scrollbar-thumb

  {

    background: #003cff;

    border-radius: 50px;

  }

  ::-webkit-scrollbar

  {

    background: #003869;

  }

  ::-webkit-scrollbar-track

  {

    background: #003869;

  }
  </style>

Feel free to add tweaks below. A few of these that I've added were inspired by @winteriscoming.
