Hide the Ribbon for Custome List, save and close

Hi All,

I have a list that is customized by InfoPath and I was trying to hide Ribbon tab for the InfoPath. Mainly Save and Close, and show edit only

One issue is that, this list is customized by InfoPath and I tried to use css and JS script.

<style>
#Ribbon.Tabs.InfoPathListTab.Commit-LargeLarge-0-0
{ display:none !important; }
</style>

and

<style>
.ms-cui-ctl-large
{ display:none !important; }
</style>
