There are some cases where you may want CSE HTML Validator to ignore, exclude, or bypass part of a document. For example, some sites (such as affiliate sites) give you bad/invalid HTML to insert into your documents, but you don't want to change or fix it because you'd rather just ignore it and leave it as it was given.
NOTE: Always use the exact syntax with case-sensitivity and no added formatting or spaces.
To ignore sections of HTML & XHTML documents, surround the section in <!--cseignore--> ... <!--/cseignore--> comments. (New v8.04)
Although its use is not recommended (the HTML compatible comments are preferred), CSE HTML Validator also provides the "cseignore" element so you can surround the parts of a document that you want to ignore in "cseignore" tags. Example: <cseignore>...ignore this...</cseignore>
NOTE: The "cseignore" element is included with the default configuration file. Other configuration files may not have support for the "cseignore" element.
NOTE: Does not ignore "high ASCII characters" for the "high ASCII" character check, if enabled.
To ignore sections of CSS documents, surround the section in /*cseignore*/ ... /*/cseignore*/ comments. Nesting of this comment is not allowed. (New v10.9923)
Note that if a /*cseignore*/ comment is found with no matching /*/cseignore*/ comment, then the /*cseignore*/ comment is not treated as a special ignore comment and no error or warning message is generated (and thus nothing is ignored).
To ignore spelling in sections of HTML & XHTML documents, surround the section in <!--cseignorespelling--> ... <!--/cseignorespelling--> comments. Nesting of this comment is allowed. (New v17.00)
