WordPress related question from a newbie: Will I need to know HTML and CSS?

[Machine]

I'm going to be putting together my first website. I'm wondering if I'll need to know HTML and CSS in order to perform basic maintenance and editing. In order to help answer that question, I'll describe the purpose of my website:

I'm thinking about starting one or maybe two different sites. The first one will be a basic blog. I would like to be able to add and remove videos and pictures to the blog whenever the need arises. The second site would be one for selling a product or two, or an e-commerce site. I'll want to be able to add and remove images and videos, too.

I've heard a lot of good things about WordPress. People say that it's pretty easy to set up and maintain. In order to meet my web objectives, would I need to learn HTML and CSS if I go with WordPress?

Not really. It certainly doesn't hurt to know the basics, but as long as you can use FTP or hire somebody to use FTP for you then you'll be all set with Wordpress.

If you stick with blogs and with WordPress, you will not need to know any HTML or CSS. WordPress generates all of that for you. WordPress is very easy to use and setup. I think the hardest part is uploading the files to your hosting.

I think the two biggest parts of being successful online is networking and writing.
