Bold sidebar menu.

Hello,

Some time ago, I’ve somehow made my sidebar menu links bold (http://www.delifort.com/, you can see the menu on the page, called “Series” - every link is bold). The problem is that I want to reverse it now, but I have absolutely no idea how I did it in the first place. I looked through everything: it’s not in Custom CSS or anywhere else.
Also, if you press on the “comment” button at the “Dazzling Popular Posts Widget”, you’ll see that the text there is partially bold too - I guess it’s bold for the same reason.

Could you please help me and tell how to fix this?
Thanks in advance.

Hello there,

I hope you are doing well today.

You can use the following CSS code to control the text boldness in the sidebar widget by going to Appearance > Customize > Additional CSS and pasting it there.

/*Boldness*/ ul#menu-series { font-weight: 100; }

However, I don’t see a comment button.

Best Regards,
