1 <!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
2 1) The <head> information in this page is significant, should be uniform
3 across api docs and should be edited only with knowledge of the
4 templating mechanism.
5 3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
6 browser, it will be re-generated from the template, json schema and
7 authored overview content.
8 4) The <body>.innerHTML is also generated by an offline step so that this
9 page may easily be indexed by search engines.

232 Override pages are a way to substitute an HTML file from your extension
233 for a page that Google Chrome normally provides.
234 In addition to HTML,
235 an override page usually has CSS and JavaScript code.
236 </p>
237 <p>
238 An extension can replace any one of the following pages:
239 </p><ul>
240 <li> <b>Bookmark Manager:</b>
241 The page that appears when the user chooses
242 the Bookmark Manager menu item
243 from the wrench menu or, on Mac,
244 the Bookmark Manager item from the Bookmarks menu.
245 You can also get to this page by entering the URL
246 <b>chrome://bookmarks</b>.
247 </li>
248 <li> <b>History:</b>
249 The page that appears when the user
250 chooses the History menu item
251 from the Tools (wrench) menu or, on Mac,
252 the Show Full History item from the History menu.
253 You can also get to this page by entering the URL
254 <b>chrome://history</b>.
255 </li>
256 <li> <b>New Tab:</b>
257 The page that appears when the user creates a new tab or window.
258 You can also get to this page by entering the URL
259 <b>chrome://newtab</b>.
260 </li>
261 </ul>
262 <p></p>
263 <p class="note">
264 <b>Note:</b>
265 A single extension can override
266 <b>only one page</b>.
267 For example, an extension can't override both
268 the Bookmark Manager and History pages.
269 </p>
270 <p>
271 Incognito windows are treated specially.
272 New Tab pages cannot be overridden in incognito windows.
273 Other override pages work in incognito windows
274 as long as the
275 <a href="manifest.html#incognito">incognito</a>
276 manifest property is set to "spanning"
277 (which is the default value for extensions
278 but not for packaged apps).
279 See <a href="overview.html#incognito">Saving data and incognito mode</a>
280 in the Overview for more details on how you should treat
281 incognito windows.
282 </p>
283 <p>
284 The following screenshots show the default New Tab page
285 next to a custom New Tab page.
286 </p>
287 <table id="pics">
288 <tbody><tr>
289 <td> <b>The default New Tab page</b> </td>
290 <td> <b>An alternative New Tab page</b> </td>
291 </tr>
292 <tr>
293 <td>

297 <img src="images/ntp-blank.png" alt="a blank New Tab page" width="200" hei ght="173">
298 </td>
299 </tr>
300 </tbody></table>
301 <h2 id="manifest">Manifest</h2>
302 <p>
303 Register an override page in the
304 <a href="manifest.html">extension manifest</a> like this:
305 </p>
306 <pre>{
307 "name": "My extension",
308 ...
309 <b> "chrome_url_overrides" : {
310 "<em>pageToOverride</em>": "<em>myPage.html</em>"
311 }</b>,
312 ...
313 }</pre>
314 <p>
315 For <code><em>pageToOverride</em></code>, substitute one of the following:
316 </p>
317 <ul>
318 <li> <code>bookmarks</code>
319 </li><li> <code>history</code>
320 </li><li> <code>newtab</code>
321 </li></ul>
322 <h2 id="tips">Tips</h2>
323 <p>
324 For an effective override page, follow these guidelines:
325 </p>
326 <ul>
327 <li>
328 <p>
329 <b>Make your page quick and small.</b> <br>
330 Users expect built-in browser pages to open instantly.
331 Avoid doing things that might take a long time.
332 For example, avoid synchronous fetches of network or database resources.
333 </p>
334 </li>
335 <li>
336 <p>
337 <b>Include a title in your page.</b> <br>
338 Otherwise people might see the URL of the page,
339 which could be confusing.
340 Here's an example of specifying the title:
341 <code>&lt;title&gt;New&nbsp;Tab&lt;/title&gt;</code>
342 </p>
343 </li>
344 <li>
345 <p>
346 <b>Don't rely on the page having the keyboard focus.</b> <br>
347 The address bar always gets the focus first
348 when the user creates a new tab.
349 </p>
350 </li>
351 <li>
352 <p>
353 <b>Don't try to emulate the default New Tab page.</b> <br>
354 The APIs necessary to create
355 a slightly modified version of the default New Tab page —
356 with top pages,
357 recently closed pages,
358 tips,
359 a theme background image,
360 and so on —
361 don't exist yet.
362 Until they do,
363 you're better off trying to make something completely different.
364 </p>
