Markdown reduces the writing interface to text. The reading experience still depends on how the page presents that text.
Start with line length and spacing
A line that is too long makes it harder to find the start of the next one. A very short line interrupts the rhythm of a sentence. The width, type size and line height should work together.
Paragraph spacing provides another quiet rhythm. Consistency here matters more than adding extra empty lines wherever the page feels crowded.
Headings are signposts
A heading expresses a relationship between sections. Plan the main sections first, then decide which ideas need a subsection. The structure of the article becomes visible before any decoration is added.
Give code a space of its own
A long line of code should scroll inside its block instead of pushing the whole page wider on a small screen.
const notes = ['Observe', 'Try', 'Write'];
const journal = notes.map((note, index) => ({ id: index + 1, note }));
console.log(journal);
Inline code such as getCollection() needs only a slight change in background to remain distinct within a sentence.
Pictures belong to the reading rhythm
A caption or nearby sentence should explain why an image belongs here. A little space lets the reader move comfortably between visual information and words.
Let structure lead
Once the hierarchy, paragraphs and lists are clear, styling can reinforce them. Many of the decisions that make an article comfortable are the ones a reader barely notices.
