4. The maximum size of the archived index.html must be less than 150 KB.

5. The archive will ignore the contents of the __MACOSX folder andDS_Store and Thumbs.db files. These are the operating system's auxiliary files which are not necessary for the HTML5 banner to work.

6. A click on the banner opens the page specified in the Link to site or Turbo page field, the mobile app (if installed), or the app page in the store (if the app is not installed). Banner clicks must open this page by calling the yandexHTML5BannerApi.getClickURLNum(1) method.

   |||UNTRANSLATED_CONTENT_START|||<a id="click_area" href="#" target="_blank">...</a> 
   // после элемента "<a href ...></a>" 
   // присваиваем для него значение атрибута href так:

   • Large banner on the Yandex Home page

     <meta name="ad.size" content="width=1836,height=572">

8. External calls to Yandex-hosted JavaScript libraries are allowed. If an HTML5 banner uses a different library, include it in the archive source code.

9. All event handlers must be explicitly specified within the script tag, for example:

   <script>
       document.onload = init;
   </script>

10. The link in an HTML5 banner must not exceed 1024 characters and must be UTF-8 encoded.

11. The banner must not use statistics collection tools (pixels, tags, etc.).

    When you create a campaign, you can specify a Yandex Audience pixel or ADFOX tag (to learn more, see How to launch a campaign). You can also use UTM tags in the link to your website.

7. The HTML5 banner size must be specified in the content attribute of the meta tag. See the example below:

   <meta name="ad.size" content="width=1456,height=180">

8. External calls to Yandex-hosted JavaScript libraries are allowed. If an HTML5 banner uses a different library, include it in the archive source code.

9. All event handlers must be explicitly specified within the script tag, for example:

   </script>

10. The link in an HTML5 banner must not exceed 1024 characters and must be UTF-8 encoded.

Requirements for expandable block

1. The expandable block must display correctly when its height changes from 360 to 675 pixels and width changes from 640 to 1200 pixels. This means that when the banner size changes within the range from the banner's minimum to maximum height and width, no artifacts or distortions should appear on the banner.

2. All important information must be centered.

3. The entire area of the expandable block must be clickable, meaning that any click on any segment of the banner must either perform the actions enabled by the interactive banner elements or lead to the advertiser website.

4. A link click must be generated by calling the method homeExpandableDesktopBannerAPI.clickAndClose(clickNum), where clickNum is the ordinal number of the link specified in the field Links to website on the ad creation or editing page. This method closes the expandable block and navigates to the advertiser website.

   |||UNTRANSLATED_CONTENT_START|||<a id="click1_area"><div>баннер</div></a>
   <script>
      document.getElementById("click1_area").addEventListener("click", function(){
         homeExpandableDesktopBannerAPI.clickAndClose(1);
      });
   </script>|||UNTRANSLATED_CONTENT_END|||

5. The banner can't be transparent or contain a frame.

6. The entire area of the expandable block must be free of elements for closing it.

7. The expandable block of the banner must have the meta tag with the ad.bgrcolor attribute that sets the layer color, for example:

   <meta name="ad.bgrcolor" content="FFFFFF">

9. In the banner's expandable block, you can add the View again button that restarts the animation scenario.

Requirements for banners with video

   var url_video = homeExpandableDesktopBannerAPI.getVideoURL();

2. If the video plays back automatically on loading the expandable block, its audio must be muted. If the video plays back on the “Play” button, the playback can start with the sound on.
3. The user must be able to pause and resume the video at any time.
4. You can't play back audio separately from video.
