Explain my HTML validator errors

Explains each error in a pasted HTML validator report in plain words, says which ones matter and shows the fix.

Task: Explain each error in the HTML validator output below in plain words and show the fix. Context: The page is [page description] and I wrote the HTML myself or with [tool or editor]. My level is [beginner, intermediate or advanced]. Rules: - Group errors that have one cause and explain the group once. - For each group say what the error means, whether it breaks anything real such as layout or accessibility, and show a before and after of at most 3 lines. - Mark errors that are harmless, and say which I can leave for later. - If the output is too short to see the cause, ask for the line it points to instead of guessing. Result: A numbered list of at most 6 groups, each with the meaning, the impact (breaks something, minor or harmless) and the fix, followed by one sentence on the order to fix them in. Material: [paste the validator output and the lines it points to here]
