Container size issue affecting site.

On my site I am using these plugins - Cool Timeline Pro - Tablepress The width of the timeline and the table is restricted (according to the support from those plugins) by the container in which they sit. This is something which can only be adjusted in the theme of course. Here are example pages: TIMELINE https://www.gayundah.info/timeline-gayundah/ You'll note there is a lot of blank space between the vertical timeline, and the timeline quick-scroll at the RHS of the page. Apparently this is due to the width of the container the timeline sits in being too narrow. TABLE https://www.gayundah.info/the-men/ You'll notice the width of the table is restricted to such an extent that the formatting settings in the plugin are not working (columns should adjust to size of longest word in the text, but instead column contents are being forced to wrap. This occurs irrespective of whether the page is zoomed in or out. You'll also note that the table width and the timeline width are the same - again pointing to a container size issue with the theme. I'd appreciate if you could tell me please how to fix this issue as it is severely impacting the look and readability of my site. Thank you.
