Interactive Tutorial Transcript

The <strike> tag is obsolete in HTML5. It was used for strikethrough text. Do not use it in new code. Browsers may still render it for backward compatibility, but you should use <s> or <del> instead.

<strike>

Use <s> for content that is no longer accurate or relevant (e.g. old prices, deprecated labels). Use <del> for deleted content in an edit or change history. Both render with strikethrough and have clear semantics.

Price: <s>99</s> 79

Migration: replace <strike> with <s> when the meaning is 'no longer correct or relevant.' Replace with <del> when you are showing a deletion in a revision. Never use <strike> in new HTML.

Was <s>available</s> sold out.

In the browser, <s> and <del> both show strikethrough. <s> = no longer accurate; <del> = deleted in edit history. Use these instead of the obsolete <strike> tag.

HTML <strike> Tag (Obsolete)

Pascual Vila

Frontend Instructor.

The <strike> tag is obsolete in HTML5. It was used for strikethrough text. Do not use it in new code. Use <s> for content that is no longer accurate or relevant, or <del> for deleted content in an edit history.

Use <s> or <del>

<s> = content that is no longer accurate or relevant (e.g. old prices). <del> = deleted content in a change or edit history (can have cite, datetime). Both render with strikethrough and have clear semantics. Replace any <strike> in legacy code with <s> or <del> as appropriate.

Best practices

Never use <strike> in new HTML. Browsers may still render it for backward compatibility, but validators will flag it as obsolete. Prefer <s> or <del> for accessibility and standards compliance.
