In our project we agreed that content editors do not use inline styling in Rich Text Fields. We did not make it impossible in the Rich Text Editor of Sitecore to use it. This can be done, but for several reasons we didn’t do this (yet).
When working on Sitecore and deploying modules to a Sitecore site we only want to deploy artifacts that are ours and not from Sitecore. This way we want to keep the deployment packages clean and fast. To manage the contents and behaviors of deployment packages we can use a wpp.targets file.
You probably have on sites with pages that show how often these are visited. This is done to show visitors that the page has attracted more people to read it and encourages them to read the article as well. This blogpost has been written using Sitecore 8.2. In older versions of Sitecore, different solutions can be used.
