HTML Comments

🎯 한 줄 통찰 (One-line insight)

HTML comments are written between <!-- and -->, are not displayed in the browser, and help document source code, hide content temporarily, and debug pages. [S1]

🧠 핵심 개념 (Core concepts)

• Comments are invisible — HTML comments are not displayed in the browser, but they can help document your HTML source code. [S1]
• Comment syntax — written as <!-- Write your comments here -->. The exclamation point (!) appears in the opening tag but not the closing tag. [S1]
• Documentation use — comments can hold notes and reminders for the author. [S1]
• Hiding content — comments can temporarily conceal content (a block, multiple lines, or a mid-line/inline section). [S1]
• Debugging aid — comment out HTML lines individually to locate errors. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Note/reminder pattern — drop <!-- reminder --> markers near relevant markup. [S1]
• Block-hide pattern — wrap one or many lines in <!-- … --> to remove them from rendering without deleting them. [S1]
• Inline-hide pattern — <!-- … --> placed mid-line hides just that fragment. [S1]
• Debug-by-elimination pattern — comment out lines one at a time to isolate the source of an error. [S1]

📖 세부 내용 (Details)

HTML comments are not displayed in the browser, but they can help document your HTML source code. [S1]

Comment syntax The basic syntax for an HTML comment is the text written between <!-- and -->. Note that the exclamation point (!) appears in the opening tag but not the closing tag. [S1]

<!-- Write your comments here -->

Adding comments Comments can include notifications and reminders. [S1]

<!-- This is a comment -->

<p>This is a paragraph.</p>

<!-- Remember to add more information here -->

Hiding content Comments can conceal content temporarily. [S1]

<p>This is a paragraph.</p>

<!-- <p>This is another paragraph </p> -->

<p>This is a paragraph too.</p>

Multiple lines can be hidden between the opening and closing comment delimiters. Comments are useful for debugging — comment out HTML lines individually to locate errors. [S1]

<p>This is a paragraph.</p>
<!--
<p>Look at this cool image:</p>
<img border="0" src="pic_trulli.jpg" alt="Trulli">
-->
<p>This is a paragraph too.</p>

Hiding inline content Comments can obscure mid-code (inline) sections. [S1]

<p>This <!-- great text --> is a paragraph.</p>

🛠️ 적용 사례 (Applied in summary)

The reminder note, the block-hidden paragraph/image, and the inline-hidden fragment above are the canonical applied examples from the source. No external project/commit applications found in the source.

💻 코드 패턴 (Code patterns)

Basic comment (HTML):

<!-- Write your comments here -->

Comment out a block of markup:

<!--
<p>Look at this cool image:</p>
<img border="0" src="pic_trulli.jpg" alt="Trulli">
-->

Hide an inline fragment:

<p>This <!-- great text --> is a paragraph.</p>
