Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown. > > - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version. > - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt). The settings in this category allow you to adjust the [Output filter](https://docs.kentico.com/k8/configuring-kentico/using-output-filters.md), which performs additional changes to the final output code of pages before it is sent to the browser for rendering. [Applying output filters to your website](https://docs.kentico.com/k8/configuring-kentico/using-output-filters.md#applying-output-filters-to-your-website) | General | | | ------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Excluded output form filter URLs | May be used to disable the Form output filter for specific URL paths, which fixes the issue with non‑working postbacks on pages that use URL rewriting. It ensures that forms, dialogs and buttons will work correctly on pages managed by Kentico. | | Excluded resolve filter URLs | Allows you to disable the URL resolving output filter, which adjusts relative URLs so that they reflect the root URL of the website.
For example, _\~/mypage1/mypage2.aspx_ would be changed to _/mypage1/mypage2.aspx_ (if the application is running in the root) or _/VirtualDirectory/mypage1/mypage2.aspx_ (when using a virtual directory).
Only URLs inside **src** and **href** attributes are changed. | | XHTML filter | | | Excluded XHTML filter URLs | May be used to specify the [URL paths of the pages](https://docs.kentico.com/k8/configuring-kentico/configuring-page-urls.md) that should be excluded from all functionality provided by the XHTML output filter. | | Excluded XHTML attributes filter URLs | Specifies the URL paths of the pages that should be excluded from the Tag attribute XHTML filter, which ensures that all attributes of HTML tags are generated in valid XHTML format. | | Excluded XHTML JavaScript filter URLs | Specifies the URL paths of the pages that should be excluded from the JavaScript tag XHTML filter, which ensures that the _type_ and _language_ attributes are included in all __ tags. | | Excluded XHTML lower case filter URLs | Specifies the URL paths of the pages that should be excluded from the Lower case XHTML filter, which ensures that all HTML tags and attributes are generated in lower case. | | Excluded XHTML self close filter URLs | Specifies the URL paths of the pages that should be excluded from the Self closing tag XHTML filter, which ensures that all HTML elements without closing tags are properly closed, e.g. __ will be replaced by __. | | Excluded HTML 5 filter URLs | Specifies the URL paths of the pages that should be excluded from the HTML5 output filter.
This filter replaces tag attributes that are obsolete in HTML5. Such attributes are removed and the system instead assigns CSS classes named in format _\__. These classes need to be defined in the CSS stylesheet used by the website's pages.
The affected attributes are: _cellpadding_, _cellspacing_, _width_, _height_, _border_, _align_, _valign_
**For example**:
__
would be replaced by:
__ | | Indent output HTML | Indicates if the HTML output of pages should be processed into a properly indented, easier to read format. This setting is applied to all pages on which the XHTML output filter is enabled. | | Convert TABLE tags to DIV tags | Determines which __ elements (and their child __ and __ tags) should be converted to elements by the output filter. The system automatically assigns CSS classes to the replacement Div tags according to the name of the original tag. The classes need to be defined in the CSS stylesheet used by the website's pages.
This behavior can either be disabled completely, enabled for all tables except for those marked by the **\_nodivs** CSS class, or only enabled for the tables designated through the **\_divs** class. |
