Adding "Advertisement" at the top of a post

Hi,

If you want to add a text inside a specific post, you need to edit the template file coresponding to the post style used on that post and add a condition to check if the post has a specific ID to echo a text on that post. Here is an example. My post has an id of 5042 so I would use this code like so:

<div class="customtext"> <?php if (is_single(5042)){
           echo "Advertisment";
        }?>
    </div>

And then use this code to style the text with css:

.customtext{
display: table;
    margin-left: auto;
    margin-right: auto;
}

You can add the css in the thme panel->custom css box

Thank you!
