New Tab Page (Desktop)

On Desktop (ChromeOS, Windows, Mac, and Linux), there are multiple variants of the New Tab Page (NTP). The variant is selected according to the user’s Default Search Engine (DSE). All variants are implemented as HTML/CSS/JS, but differ in where they are hosted.

  • Google: either the Remote NTP (as of 2017-12-05, the default) or the Local NTP, with Google branding (as of 2017-12-05, planned to replace the Remote NTP and in experiments on Beta).

  • Bing, Yandex: a Third-Party NTP, where the NTP is hosted on third-party servers but Chrome provides some of the content via elements.

  • Other: the Local NTP with no branding.

As of 2017-12-05, Bing and Yandex have implemented third-party NTPs. The full list is in prepopulated_engines.json, under the key "new_tab_url".

All variants show up to 8 NTP Tiles. Each NTP tile represents a site that Chrome believes the user is likely to want to visit. On Desktop, NTP tiles have a title, a thumbnail, and an “X” button so that the user can remove tiles that they don’t want.


Local NTP

Google branding

One Google Bar

The One Google Bar (OGB) is at the top of the NTP. The NTP fetches the OGB from Google servers each time it loads.

Google Logo

The Google Logo is below the OGB. By default, it is the regular Google logo. It can also be a Doodle, if a Google Doodle is running for a particular combination of (today’s date, user’s country, user’s birthday).

No Doodle

On a day when there is no Doodle (in the user’s current country), the NTP shows the Google logo. It comes in two variants:

  • Colorful, if the user is using the default theme, or on any other theme with a solid black (L=0%), white (L=100%), or gray (S=0%) background color.
  • White, if the user’s theme has a background image, or if the background is a solid color, but not black, white, or gray.

Also, even on days when there is a Doodle, if the user’s theme’s background is not solid white, new NTPs show the Google logo by default. In this case, an animated spinner advertises the Doodle. If the user clicks on the spinner, then the NTP resets to the default theme and shows the Doodle.

Static Doodles

A Static Doodle shows as a single static image. When clicked, it triggers a navigation to the Doodle’s target URL.

Animated Doodles

An Animated Doodle initially shows a static Call-to-Action (CTA) image, usually with a “play” icon. When clicked, it swaps out the CTA image for an animated image. When clicked a second time, it triggers a navigation to the Doodle’s target URL.

Interactive Doodles

An Interactive Doodle is embedded into the NTP as an <iframe>. The framed content usually contains a CTA image, but this is opaque to the containing NTP.

The embedded Doodle can ask the containing NTP to resize the <iframe> tag to enlarge the space available for the Doodle. To do this, it sends a postMessage() call to window.parent. The event data supports these parameters:

  • cmd (required string): must be "resizeDoodle".
  • width (required string): a CSS width (with units). Because the Doodle cannot know the size of the outer page, values based on "100%" (e.g. "100%" or "calc(100% - 50px)") are recommended.
  • height (required string): a CSS height (with units). Must not be a percentage, but otherwise any units are OK.
  • duration (optional string): a CSS duration, such as "130ms" or "1s". If null or absent, "0s" (no transition) is assumed.

For example:

// Reset to initial width and height.
window.parent.postMessage({cmd: "resizeDoodle"});

// Transition smoothly to full-width, 350px tall.
    cmd: "resizeDoodle",
    width: "100%",
    height: "350px",
    duration: "1s",

The Fakebox looks like a search bar, so that the NTP mimics the appearance of the Google homepage. It’s not actually a real search bar, and if the user interacts with it, the NTP moves keyboard focus and any text to the Omnibox and hides the Fakebox.


Below the NTP tiles, there is space for a Promo. A Promo is typically a short string, typically used for disasters (e.g. “Affected by the Boston Molassacre? Find a relief center near you.”) or an advertisement (e.g. “Try the all-new new Chromebook, with included toaster oven.”).

As of 2017-12-05, the Local NTP does not yet support Promos.

Non-Google Local NTP

A non-Google local NTP shows only NTP tiles, with no branding. The tiles are centered within the page.

Remote NTP

The Remote NTP is hosted on Google servers. It is intended for removal, and is not documented here.
