Impressive Tumblr tricks aren't difficult to pull off when you learn a little HTML. If you've seen buttons, menus and textboxes on Tumblr pages, they're there because people added them as HTML elements. Two types of textboxes exist on Web pages. Regular textboxes consist of one row while larger textarea elements may contain multiple rows. Add either of these elements to your Tumblr blog by copying and pasting simple HTML tags into its Description box.

Step 1

Log in to Tumblr and click the gear icon. Click the name of the blog you wish to update followed by "Customize."

Step 2

Paste the code shown below into the Description box:

<input type="text" value="My Input" size="20">

This is an HTML input tag that creates a regular textbox. Replace "My Input" with the text you want to appear in the textbox. The tag adds a blank line after the textbox.

Step 3

Paste the following code below the code described in the previous step:

<textarea rows="8" cols="20">My Input</textarea>

This code creates a textarea that's eight rows high and 20 columns wide. Replace "My Input" with the text you want people to see when they view the textarea. You can also change the values for rows and cols to other values if you'd like your text area to have different dimensions. Click "Save" to save your changes.
