## Typography

We can use 'mark' to highlight text.

We can visually delete text using 'del' or we can mark it as just strike through using 's'. The difference is semantic.

We can visually insert text using 'ins', or we can mark it as underline using 'u' without the semantic value.

small and strong and em for italicized.
