Right sidebar and tiddlers' width remain fixed without adjusting to the width of my browser

Hello

I don’t understand why the position of my right sidebar and the width of the tiddlers remain fixed without adjusting to the width of my browser when it works on the tiddlywiki site?

Thank’s to someone can help.
