writing text for epub3

No, that is an error. If you are going to do so, then directly build an epub2 ebook. You need to employ all css3 tools to give the best reading experience to those ones with modern ereaders and after that, to write fallback code for old ereaders. For example, with epub3 you can avoid fragmentations (that is, no blank spaces are generated by pictures, tables, etc.) while in epub2 that is not possible (but there are ways to deal with them). So, are you going to allow fragmentations in your epub3 because the code to avoid them is not honored under epub2?

I'm curious, what exactly is it where the blank spaces come into play? When placing an image in an EPUB2 there will added blank spaces? And what's the required code for EPUB3 to avoid them?

I wrote about that in several posts; read the following one:

And yes, when placing an image in an EPUB2 there will added blank spaces because epub2 can't float images vertically and so doesn't allow the text to fill blank spaces. But epub3 allows a better handle of images and of that way, blank spaces (fragmentation) is avoided. Read the posts I indicated above and there you'll be able to watch some examples about you can get with epub3.

EDIT: Here you can also watch how images looks under epub3 even in landscape mode (at full and half page):

I get what you're saying.
But here's why I'm doing it this way.... In Sigil, I can start with epub2 or epub3. If I am making an epub2, and then I learn about some good feature that works only in epub 3, I won't be able to add it. And I honestly don’t know how hard or time-consuming it will be to change it to epub3. But, if I start with epub3 then I can always add advanced epub3 features easily.

Install ADE 2.0.1. It's great for testing backwards compatibility.

You can convert epub2 to epub3 very easily with the Sigil's plugin ePub3-itizer:

The plugin does all the work for you.

Are you saying that if Adobe Digital Editions 2.0.1 can show an epub3 (or some feature of epub3) correctly, then it means that epub3 (or that feature of epub3) is backward compatible? If so, then this is very helpful to know. Thank you so much for your help.

Thank you so much. I didn’t know about this plugin, sounds like a really easy solution. I’ll definitely try it out. Thanks again for taking the time to help me.

ADE 2.0.1 does not do ePub3. So it's a good way to see how well your ePub3 looks on a program that only does ePub2.

I know that we do this:
use &lt; instead of <
use &gt; instead of >
use &amp; instead of &
My question: Are there other things on the keyboard that we don't put directly from the keyboard?
Thanks a lot

No need to do any of those unless you are directly editing HTML. That's like Notepad in 1994 to build a website.

You write in a word processor or text editor. You might edit converted to HTML directly if it's a textbook.

I have installed Adobe Digital Editions 2.0 (I couldn’t find Adobe Digital Editions 2.0.1). Since 2.0.1 comes after 2.0, they must have released ADE 2.0 first, so I’m sure ADE 2.0 does not do epub3.

I am learning Sigil and learning to use both ways: through PageEdit, and through Code View. Sigil and PageEdit both are great softwares.
