Copying text from Word, Google Docs, or email brings invisible formatting code with it. It looks fine in the editor but breaks on the live site — wrong fonts, odd spacing, rogue line breaks.
Already pasted it? Select all the affected text and use the Remove formatting button (Tx icon). Then reapply only the formatting you actually need.
The heading levels (H2, H3, H4) aren't just about making text bigger. They tell browsers, search engines, and screen readers how your page is organised.
A good test: if you removed all the body text, could someone navigate the page using just the headings?
Screen readers read out link text in isolation. "Click here" and "read more" tell people nothing.
