Edit or change a style

I reopened a completed project to check a reference and found most of the styles implemented had been severely changed. Not sure if this was due to the newer beta versions or something else, but the entire project is a mess because of these style gremlins.

How does one go about changing an existing style? Block Quotes is a good example. It is now half the width of the page even though it does still retain the small left indent.Below is a simulation of the problem.

get to show off. You can talk to
everybody like you do, and maybe
you will get some good information
that we can use.” .

Format > Style > Redefine Style from Selection…

What xiamenese said. Select a paragraph that is in the style you want to change, alter the formatting of that section to how you want it and then select “Redefine Style from Selection”. It should update the style for the entire project
