Obsidian strives for maximum capability without breaking any existing formats. As a result, we use a combination of flavors of [[Basic formatting syntax|Markdown]]. Obsidian supports [CommonMark](https://commonmark.org/), [GitHub Flavored Markdown](https://github.github.com/gfm/), and [LaTeX](https://www.latex-project.org/). Obsidian does not support using Markdown formatting or blank lines inside of HTML tags. ### Supported Markdown extensions Syntax | Description -|- `[[Link]]` | [[Internal links]] `![[Link]]` | [[Embedding files]] `![[Link#^id]]` | [[Internal links#Link to a block in a note\|Block references]] `^id` | [[Internal links#Link to a block in a note\|Defining a block]] `%%Text%%` | [[Basic formatting syntax#Comments\|Comments]] `~~Text~~`| [[Basic formatting syntax#Styling text\|Strikethroughs]] `==Text==`| [[Basic formatting syntax#Styling text\|Highlights]] `` ``` `` | [[Basic formatting syntax#Code blocks\|Code blocks]] `- [ ]` | [[Basic formatting syntax#Task lists\|Incomplete task]] `- [x]` | [[Basic formatting syntax#Task lists\|Completed task]] `> [!note]` | [[Callouts]] | (see link) | [[Advanced formatting syntax#Tables\|Tables]]
