XHTML Tutorial: XHTML basics for beginners 3

XHTML syntax

To put it simply, you must use clean HTML syntax to write XHTML.

Some other syntax requirements of XHTML:

The property name must be in lowercase. For example:

Error code:

& Lt; table WIDTH = "100%" & gt;

Correct code:

& Lt; table width = "100%" & gt;

 

The property value must be referenced. For example:

Error code:

<Table width = 100%>

Correct code:

 

& Lt; table width = "100%" & gt;

The abbreviation of the attribute is forbidden. For example:

Error code:

<Dl compact>

<Input checked>

<Input readonly>

<Input disabled>

<Option selected>

<Frame noresize>

 

Correct code:

 

<Dl compact = "compact">

<Input checked = "checked"/>

<Input readonly = "readonly"/>

<Input disabled = "disabled"/>

 

<Option selected = "selected"/>

<Frame noresize = "noresize"/>

List a table to let everyone know:

HTML XHTML

Compact = "compact"

Checked = "checked"

 

Declare = "declare"

 

Readonly = "readonly"

Disabled = "disabled"

 

Selected = "selected"

Defer = "defer"

Ismap = "ismap"

 

Nohref = "nohref"

Noshade = "noshade"

Nowrap = "nowrap"

Multiple = "multiple"

Noresize = "noresize"

Replace the name attribute with the id attribute. For example:

In HTML 4.01, a name attribute is defined for a, applet, frame, iframe, img, and map. In XHTML, the name attribute cannot be used and should be replaced by id. For example:

Error code:

Correct code:

Note: In order to make the old browser execute the content normally, we can also use the id and name attributes in the tag. For example:

In order to adapt to the new browser browsing, we added the/tag in the above code to end.
