In order to place a donate button in center of block, follow the following steps:

 

1. Select Edit in the block where the donate button is placed. Then you will be moved to edit mode


2. Select Edit for block.

   Then, an iframe embed code for the donate button should be displayed. 

   <script src="...">

   <a class="dbox-donation-button" href="..."...></a>


3. Add a new div tag with `donate-button` class above this code. 

    <div class="donate-button">

       <script src="...">

       <a class="dbox-donation-button" href="..."...></a>

    </div>


4. Add a stylesheet for centering below the div tag.

    <div class="donate-button">

       <script src="...">

       <a class="dbox-donation-button" href="..."...></a>

    </div>

   <style type="text/css">

        .donate-button {

           text-align: center;

        }

   </style>


When you've done this, the process is complete.
