TiddlyWiki CSS Styling: .annotation-wrapper, .tc-tag-label, and .tc-fish-title

The CSS code provided is used to style a wrapper element and some specific elements within it. Here is a breakdown of what each part of the code does:

1. '.annotation-wrapper': This is a class selector for the wrapper element. It sets the minimum width to 500px, scales down the wrapper to 70% of its original size, sets the transform origin to the top left corner, adds a margin of 15px on the top and bottom, adds a padding of 10px, hides any overflow in the y-axis direction, and disables user selection of the content within the wrapper.

2. 'button.tc-tag-label, span.tc-tag-label': These are selectors for buttons and spans with the class 'tc-tag-label'. It sets the white-space property to 'normal', which allows the text to wrap onto multiple lines if needed.

3. '.tc-fish-title': This is a class selector for elements with the class 'tc-fish-title'. It sets the font size to a value specified in the TiddlyWiki theme variable 'bodyfontsize' and the line height to a value specified in the TiddlyWiki theme variable 'bodylineheight'.

Overall, this CSS code is used to style a wrapper element and some specific elements within it, such as buttons, spans, and titles.
