How do I control the last character of a string?

[simona6]

I have a string in a TD tag that says "100 g".

The 'g' is grams, but it's not in it's own Span, so I need a way to find the 'last character', and then hide it in CSS.

I can see how to do ::first-letter, but there doesn't seem to be a way to do Last-Letter.

Is there?

It's not possible to target the last letter with CSS afaik. 

CSS generally depends on having the proper structure/markup to target things and if that's missing there's not much you can do.   ::first-letter exists because stylizing the first letter is a common thing that places do so it made it into the spec as a convenience feature so authors didn't have to do <span class="first-letter">*</span> everywhere.  Stylizing the last letter is not that common in my experience so it's not in there. 

So if you want to stylize your suffix you'll need to tag it with a span, or just remove it if all you want to do is hide it.

If you're desperate to do it and kicken's far better suggestions can't or don't work for you, you can use JavaScript to find the last letter and remove it or wrap it in a span that  you can then style separately. Assuming you have a way to target the specific paragraph with the last character to remove, of course.

I guess my question is why the letter is even there in the first place if you don't want to see it.

Yes i should have added this here.

their shop has % instead of weight, and in the cart it still shows 100kg rather than 100%.

For some reason, Wordpress's logo translate won't change that.  It will change what shows in the Dropdown in Woocommerce, but not the front-end "you have 100kg in your cart" text.  So thought i could simply hide the 'kg'. Or the 'g' if it is just grams.

For one, percent and weight are not interchangeable units. I can't imagine why a thing is being labelled with a "kg" unit when it's supposed to be a percentage. It doesn't make any sense. It isn't the sort of problem that should exist.
For two, I can't imagine why someone has a thing in a (shopping?) cart that is measured in percentages.

Sweeping this problem under the rug is not the answer. You need to deal with the fact that WP or whatever is attaching incorrect units to the items. Because there's a really, really good chance that the wrong units are a symptom of a larger problem.
