Web Slices are a web feed technology based on the hAtom Microformat^[1] that allows users to subscribe to portions of a web page.^[2][3][4][5] Microsoft developed the Web Slice format, and published a specification under their Open Specification Promise.^[1] The specification is not published by any independent standards body. Introduced in Internet Explorer 8 Beta 1, Web Slices can be previewed in a fly-out window.^[6] As of 2012,^[update] Internet Explorer 8 and 9 were the only browsers to support Web Slices natively, although Mozilla Firefox had support via an add-on called webchunks.^[7]

A Web Slice has 9 properties: the Web Slice id, entry title, entry content, end time, alternative display source, alternative navigation, alternative update source, and time to live.^[1] The 3 required properties are: the Web Slice id, entry title, and entry content.

To disable Web Slices on a web page, add:^[8]

<meta name="slice" scheme="IE" content="off"/>

To specify the default web slice on a page with multiple web slices, add:^[8]

<link
    rel="default-slice"
      <!-- Must be "default-slice" -->
    type="application/x-hatom" 
      <!-- Must be "application/x-hatom" -->
    href="id of webslice"
      <!-- The ID of the web slice -->
/>

<div class="hslice" id= "hslice-id goes here">
  <!-- The ID of the hSlice -->
    <div style="display:none" class=<"entry-title">Title goes here</div>
      <-- The title -->
    <span class="ttl" style="display:none">360</span>
      <!-- How often to refresh in minutes -->
    <abbr class="endtime" title="10 Jan 2020 00:00:00 UTC"></abbr>
      <!-- When the link expires -->
    <div class="entry-content">
        The content goes here
</div>

While Firefox does not have built in support for web slices, extensions have been created to give the ability to read web slices.

WebChunks is a Mozilla Firefox 3 implementation of Microsoft Webslices. It allows you to "follow" an area of a web page through a dedicated feed bookmarked in a new toolbar. With Greasemonkey, WebChunks can insert webchunks or webslices markup into any web page so the Webchunks extension handles it.^{[7][9][10][11][12][13]}

Fireclip is a Firefox addon that lets you "clip out" parts of a website and watch them for changes. It lets you track specific parts of a website in a similar manner to web slices.^{[14][15][16][17][18][19]}

Pageslices was another Firefox addon that allowed not only storing parts of websites but also organizing them by adding on custom pages.^[20]

Google Chrome, like Firefox, does not have built in support for web slices. However, the extension API new to Chrome 4 allows extensions to be created to give the ability to relatively simply create arbitrary webslices^[21] of any content from any page.

Although it was rumored that Opera 10 would have support for web slices, this did not come to pass.^[22][23] Opera does have a "widgetize" feature likened to web slices which allows web pages to be displayed on a user's desktop.^[24]
