HTML Attributes
HTML Attributes
- Provide additional information about HTML elements.
- All HTML elements can have attributes.
- Are always specified in the start tag.
- Usually come in name/value pairs like: name="value".
Use Lowercase Attributes
Quote Attribute Values
- We recommends quotes in HTML, and demands quotes for stricter document types like XHTML.
- Using quotes are the most common. Omitting quotes can produce errors. We always use quotes around attribute values.
- Double quotes around attribute values are the most common in HTML, but single quotes can also be used.
- In some situations, when the attribute value itself contains double quotes, it is necessary to use single quotes. Or vice versa. <p title='John "ShotGun" Nelson'>.
