Text Align buttons disabled

[mjp77]

Dear all,

I am a little bit new to Contribute, but have created a site that is working
pretty well. The only issue I'm having is that the ability to align text
(center, left, right, justify) is disabled in Contribute - the buttons are
grayed out. I have gone into administer roles, and I don't see anything that
restricts this in particular. Everything else is enabled - fonts, font sizes,
font colors. Only the alignment is disabled.

There is a need to be able to center images on the site. Is there something
I'm missing that can get this enabled?

Thank you.

I had template with

<style>
td {text_align: left}
</style>

<div align="center">
<table width="750">
main content
</table>
</div>

the td setting in the style sheet caused the text align buttons to be disabled
in Contribute (3.11)

I workee round this by removing the td text align style and recoding the the
table

<table wifht ="750" align ="center">
</table>
