In the latest SEO Office Hours Shorts, JM had some good advice for someone who asked if displaying partial product names is considered a violation:

"I don't see how this would be considered a violation. Showing a part of the full product name is okay."

"I would *recommend making sure that in the structured data you actually have the full name*. It makes it a little bit easier for us to recognize which product this specifically is, so that when we can tell that someone is searching for that product, we can also show your offer there."

"One thing I might recommend taking a look at, is you can also do some of this with CSS. Which means that *in the HTML you can still have the full name, but with CSS you can kind of shorten it to whatever fits into your design*. ... But this is kind of like a technical implementation question. Like, should you do it with CSS or can you do it with maybe JavaScript or something server side? That's totally up to you."

Love this response - also aligns with the recent GSC video about CSS & SEO, ICYMI.
