Umbraco

Very nice article, I currently use a custom html helper which allows me to render css/scrippt blocks in partials and have it rendered in the right places (styles in head etc) I may look at the taghelper approach though after reading your article.

I especially love how natural the html looks using the tag helper. That's important to me because the frontend developers that I work with don't usually know how to use things like html helpers.

You mght want to change `output.Attributes.Remove(existingAttribute);` into
```            if (existingAttribute != null)
            {
                output.Attributes.Remove(existingAttribute);
            }```
If the element has a style and no existing class it errors 😄

oof, good observation! I'll fix that right away!

Actually, looking at the docs, it's also fine without the null check:

I guess a null check can't hurt and shows more intent anyway, I'll add it in the post

It's strange that visual studio doesn't give a warning about nullability here in my solution

<@248382845599350785> I also noticed that this breaks inline styles in the backoffice for blocks 😄

I added this to the top of the process method
```
            if (_httpContextAccessor.HttpContext.Request.IsBackOfficeRequest())
            {
                output.Attributes.Add(new TagHelperAttribute("style", new HtmlString(Style)));
                return;
            }```

Ah, good to know, I'll add that to my example. You're awesome for trying it out and giving me valuable feedback like this 😊

You're welcome, it's a great little taghelper.
