Where are the buttons, in the toolbar?or
Why don't I have a Colour / Font / Jump Break / Video Upload / whatever selection, in my post editor?The reason is very subtle - and not easy to spot.
Blogger page / post editor is very elegant, with no feature being colourfully different. Most people compose their posts in Compose mode - and don't use HTML Mode, except for specific needs - or maybe by accident.
And the people who don't use HTML mode, intentionally, can't always spot the difference, in the mode selector buttons.
Here's two shades of gray, in the mode selector buttons.
Compose mode: What most blog owners generally use. Has more buttons in the toolbar.
HTML mode: What many blog owners seldom use. Has less buttons in the toolbar.
You may not be able to spot the difference, above. I bet that you can spot the differences, below!
Compose mode, again.
HTML mode, again.
And here, we see the toolbars. I bet that you can spot the difference, in the toolbars - but, honestly, could you spot the differences between the mode selector buttons, without being told what to look for?
It's not hard to spot, when you know about it. For somebody who doesn't know about it, maybe even clicked on the button without realising, I bet it's a bit scary.
Why did Blogger design post editor mode selection, this way? One more mystery, for the books.
Just note one additional Blogger oddity, which you may observe when toggling the mode selector.
At any rate, if you ever find yourself observing the lack of buttons, in the page / post editor toolbar, just click on the "Compose" button. And, if clicking on the buttons does not provide improvement, try checking cookie filters, and then checking script filters.
