I added your lines to the css file, but still the alignment does not work. I even switched the theme back to Black Candy, and that did not help either. So I switched it back to Tutorial, with your css lines pasted in the right file and saved.
Next, I tried to place an image in my doc again. When doing so, I selected the following from the Alignment / Style dropdown box "On the right, with text wrapping around". But the image appeared on the left, with no text wrapping.
I checked the html box, and found the following code:
<div class="captionImage right" style="width: 100px;"><img class="right" src="assets/MyImage.JPG" alt="test" title="test" width="100" height="100" />
Seeing that the class was captionImage, I searched for "captionImage" in every file in the css folder in both the Tutorial theme and the Black Candy theme, but I could not find it.
If the captionImage class is not available, why is it being inserted automatically by tinymse when I use the Alignment / Style dropdown box as described above?
As for the tutorials, I did complete the first 2. Though I did not time my effort, I believe much more than 2 hours passed. As I progressed, I did understand some of the concepts, but increasingly, I found myself mindlessly pasting code without really understanding. So I stopped, and read up on php classes instead.
On the one hand, I realize I am lacking some knowledge, but on the other hand, I have programmed in php and MySQL for years, not as a pro but merely as my work requires it, so I feel a bit silly that I cannot figure this out.
