Open Webs Editor
Navigate to the page where you'd like to add your Microblog plugin.
Add HTML Code
At the bottom of the Webs editor are the various site components. Click Other to reveal the Custom HTML component. Then, drag the Custom HTML component to where you'd like your Microblog plugin to appear on the page.
A gray Custom HTML box will appear on your page.
Double click the box to open the popup where we'll paste the HTML in the next step.
Paste this code into the gray box and save.
Note: Webs elements do not change size automatically. So you might need to change the height of the HTML box. Do this by changing the height="600px" to a higher number.
Edit your Microblog on Webs:
Go to the live Webs web page and select the settings gear in the upper right corner of the Microblog Plugin.
