Use semi-bold instead of bold in the text editor

In my site styles, I have my paragraph font set to Halyard Display, with the default weight 400. When I am formatting text in a text box, and I set the text to 'bold,' it automatically switches to the heaviest weight of Halyard Display (900). Is there anyway to tell it to use a different weight (like 600) for the 'bold' style across the website, instead of defaulting to 900 for all bold text? 

Hi, For semi-bold you need to set the font weight to 600. 

On your Squarespace dashboard, go to website > website tools > custom css. Then add this code.

p {
 font-weight: 600 !important;
}

This code will set all the paragraphs weight to 600 (semi-bold).  

That's not what I'm asking—I don't want to set all of the paragraphs to 600 (semi-bold). I want the paragraphs to remain at 400 (regular), but the 'bold' weight to be 600 (semi-bold) instead of 900 (extra-bold). So when I format text in the rich text editor to be bold, it will be 600 instead of 900.

Try this one:

It'll only change the weight of the bolded paragraphs to 600. 

p strong {
  font-weight: 600 !important;
}

Thanks, I was finally able to find another thread on this question and the advice there worked. (injecting the CSS you said, but additionally had to make sure Squarespace was loading the weight I needed)
 

Awesome!!

The solution in the post you mentioned is changing the fonts of all bolded texts, not just paragraphs.

Not sure what else could have been done to make sure Squarespace is loading the expected weight. If you can share your solution that might help others facing the same issue. Thanks!
