The fonts looked great until this morning, when the font lost its bold style as you can see in the pictures.
It used to be bold and now it is tiny, and plus, all code blocks in the pages looks smaller, and I don't know why.
I captured the first image which has bold font as it is a web page that was opened yesterday: if I refresh the page, it would look like the second image.
Should be like this.
Now looks like this.
