Free templates are everywhere man! As far as simple editing of text. DL notepad++ and open the html file with it. Find the text you are trying to change with "find". Revise with your pitch or sales copy accordingly.
Images- LITERALLY you can look at an images or img folder for the name of the image you wish to change. Add your new image to the file. (since you know no html then make the new image the exact same size until you learn more) Now, open the html file and search "find" the old image name and replace it with the new image name. (you should have a backup "original copy" and also have the copy you're editing open in a browser...simply refresh to view changes

)
Links - same basic procedure. Open file with browser. Hover or click undesired link to get the url that needs replaced. notepad++ => open html file => find "the old url" => replace with new one.
Colors - Open html file with firefox browser. Find a color in your template you hate. Right click and select inspect element. A large editor box will pop up.
Look for any tag listed in the right for color that looks like this #66ff66 That 6 digit code is a hex code. You can look them up, they're so easy they're dangerous.
Without getting into color theory and psychology...basically....If you can't color coordinate then don't touch this part yet. Just find something you find visually appealing.
But if you still want to play with color, follow the instructions and do it to this thread. Find colors and replace them. Refresh the page to undo your "changes" simple as that.
Fonts and bolding are also easy to change. Knowing when to change them and what to change them to to create stunning impact requires a little graphic design knowledge.
But, in leiu of that....modern font trends focus on simple and easy to read. I'm sure your "artistic" font kicks ass! But not if the target is old and trying to read it on a tiny smartphone. Don't get crazy if it is NOT completely necessary!
In 45 seconds you now know how to do basic alterations to any html based template with no required knowledge of CSS3, HTML5, JS or PHP. Perhaps next lesson I will teach you how to steal an entire html website in seconds. (you shouldn't do this and it will not work on dynamicly created sites)
If you already knew this...wonderful. Most do! But you'd be surprised how many spoon fed computer users DON'T.
If you don't know how to FTP to a web host...LEARN IT...It's simple.
Wordpress does make things simple...there are ways to make it do even more awesome things than is intended. But with frameworks you do eventually hit
a limit as to what is out there and how much you can actually do yourself. Most frameworks are written in PHP (the mainstream ones), unless you have a programming
background or are REALLY determined...you WILL be hiring someone else. (am personally facing that right now!)
The good news is...for most "static" site you'd be creating...PHP is 1000% unnecessary!
DO LEARN...html & css when you get a chance. Take notes and practice the basics! This is key! Once you can create all by yourself then look at bootstrap.
It is a (non php) framework to make client side development a little easier.
