Style specific text box

Hello– I'm having trouble identifying how to target and style a specific text module. I'm looking around in Chrome's inspect but can't seem to find it. On the home page, it's the line near the top that reads 'Entrepreneurial Insights from a Startup Veteran'. I need to adjust the weight of the font. Thanks!

Might be a cleaner way to do this, but the easiest way to target that text is "#block-6a5984dad3cbc96af63c > div > h4 > strong" - let me know if you need anything extra here 🙂

Ok, I targeted this block but it doesn't seem to fully respond to the font-weight property. I'm trying:

#block-6a5984dad3cbc96af63c h4 {font-weight: 300!important;}

The only weight that seems to have any effect is 800, but the font is Proxima Nova so technically it should also have 300, 400, 500 etc.
