Targeting letters within a word to change colour using CSS or JS?

I'm trying to figure out if there's a quicker way to write something like this:

<span class="brandname"><span style="color: #0399f0">Company</span>Name</span> <span class="tagline">TagLine</span> 

What should happen is CompanyName gets wrapped in the class brandname which is a specific font, weight, and text-decoration, and then first half of the name (Company) should be in blue while while the rest of it is default (black). And then Tagline is wrapped in a class called tagline which displays a different font etc.

Does anyone know if I can just use the class brandname to target the first half of CompanyName. Looking for a way to save keystrokes for the future.

I feel like the way I'm doing it now would affect SEO. Majority of my googling has resulted in links from 2012-2014...my guess is nth-letter still doesn't exist but was worth asking for alternative.

Thanks for your help!

You could do something like this CSS only, but in this case you have to add the content you want in another color to the css part:

HTML:

<span class="brandname">Name</span> <span class="tagline">TagLine</span>

CSS:

.brandname::before {
  content: "Company ";
  color: #0399f0;
}

I myself would still prefer the solution with the 2 span elements.

I ran into the same before. Unfortunately I couldn't find CSS only solution.

Then I stumbled upon this pen . This uses jQuery to style the n-th selector.

/*
# nth-Everthing made with js. #

##Implemented nth- ##
:nth-letter
:nth-word


## Implemented last-##
:last-word
:last-letter

## Implemented first- ##
:first-word (faster than :nth-word(1))


## Things that work ##

Add a hover effet to each odd letter
  .className:nth-letter(odd):hover{}


Add a hover effect to :before/:after
  .className:nth-letter(odd):hover:after{}



## Things that don't and will not work ##
.className:before:nth-letter
