Tumblr Theme Submitter Name – How to Display Submitter Name in Tumblr Theme

1. Go to the Customize section after you log in
2. Click on the Theme tab
3. Click Use custom HTML

This will bring up a edit box that contains the HTML and tumblr code used by the theme.

Put the code for the tags somewhere between the opening {block:Posts} and closing {/block:Posts} tags.

To start off easy, let's put the tags at the bottom of all your post types.

Where you see the following line:

{/block:Posts}

Insert the following starting chunk to look like this:

    {block:HasTags}
       {block:Tags}
          <a href="{TagURL}">{Tag}</a>
       {/block:Tags}
    {/block:HasTags}

{/block:Posts}

1. Click Update preview in the lower right corner of the edit box (or it will update itself)
2. Click Save + Close in the upper right of the dashboard.

Refresh your tumblr blog and you should now see the tags display.

You can read more of the specific tags markup needed on the Tags section of "Creating a custom HTML theme"

It may be tedious, but it looks like you'll have to include the HasTags block in each of the section types.

Starting with the first you'll end up with this:

    {block:Text}
       <li class="post text">
           <!-- HTML layout for Text posts -->

        {block:HasTags}
            {block:Tags}
                <a href="{TagURL}">{Tag}</a>
            {/block:Tags}
        {/block:HasTags}

       </li>
    {/block:Text}

Where you currently have it appear just before {/block:Posts}, change it to be just before the closing </li> which appears to be what your post container styles are dressed in.

Don't forget to remove the block that appears just before the closing {/block:Posts} or you'll get the tags showing up twice.
