无法在BE中设置TYPO3内容元素边距

Question

I've a problem with TYPO3 content element margins. I am using TYPO3 version 4.7.2. When I set margins in the 'Appearance' tab - 'Content Element Layout', Top Margin and Bottom Margin, the margins are not recognized and displayed in FE.

I've added a typoscript code "tt_content.stdWrap.innerWrap >" in my TS template setup and it's not working.
