How to remove Created & Modified part in SharePoint 2013?

You can edit view page in SharePoint Designer and remove created and modified from the form.

Go to the list, choose list (close to files and browse)
Choose form web parts and deafult display form.
In the editor click add a webpart and find "script editor".
In script editor you can link to an css file (put the css file in style library and link in the script editor) or just put in the css code (remember the tags).

<style type="text/css"> .ms-formtoolbar{ display:none; } </style>
Save this file in style library and refer this file in content editor web part on displayform.aspx. check the image on how to go to display form in lists.

Hi there Ramkisan!

Thank you for your kind response...

If we'll edit it in SP Designer, could you please help us which one to edit and how...

Or if your second advise is much better, could you please help us advise step by step?

Thank you and hope to hear again soon...

:)

We couldn't find the List that you're saying... Please check on the attached screenshot.

We try to follow on your instructions but couldn't find the List on the ribbon...
