Twitter Widgets Webpage Properties

Websites can set widget preferences across their entire website by including <meta> and <link> elements in every page for interpretation by Twitter’s widget JavaScript before creating a new widget or button.

Widget settings specified in a <meta> may be overridden at the individual widget level. Order of precedence:

web intent link query parameter
widget attribute
widget ID stored preference (embedded timelines only)
meta or link element

Disable DOM scan for widgets and buttons

Twitter’s widgets JavaScript scans document.body after initialization to locate buttons, widgets, and web intents for enhancement. Disable this scan if Twitter content is only loaded via JavaScript factory functions or if you prefer to directly call Twitter’s loader on a smaller fragment of the page.

<meta
  name="twitter:widgets:autoload"
  content="off">

Canonical link

The Tweet Button uses the canonical link relation of the page expressed in a <link> as the shared URL if the URL property is not set in the button markup.

Add a canonical link in the <head> section of your webpage.

<link
  rel="canonical"
  href="https://dev.twitter.com/">

Identify the Twitter profile of the page

Populate the via property of a Tweet Button by linking to your Twitter profile page with a me link relationship token.

Set a me link relationship in the <head> section of your webpage.

<link
  rel="me"
  href="https://twitter.com/TwitterDev">

You may also set a me relationship from an anchor element on your page, such as a Follow Button.

<a
  class="twitter-follow-button"
  rel="me"
  href="https://twitter.com/TwitterDev">
Follow @TwitterDev
</a>

Theme

Override the default light theme preference for an Embedded Tweet or an Embedded Timeline.

<meta
  name="twitter:widgets:theme"
  content="dark">

Default view	theme = dark

Link color

Specify a hexadecimal color value for Tweet links displayed in an Embedded Tweet or an Embedded Timeline.

<meta
  name="twitter:widgets:link-color"
  content="#ff00ff">

Border color

Specify a border color for any Embedded Timelines displayed on the page.

<meta
  name="twitter:widgets:border-color"
  content="#ff00ff">

Do not track

Twitter may use website impression data to tailor Twitter experiences including suggesting accounts to follow. Your website can choose to opt-out your audience from tailored experiences informed by the content of your site by setting dnt=on.

<meta
  name="twitter:dnt"
  content="on">

Disable functionality which may trigger Content Security Policy warnings

An Embedded Tweet or Embedded Timeline may display with restricted capabilities when a Content Security Policy restricts inline loading of Twitter. Set csp=on to disable functionality which could display Content Security Policy warnings on your site.

<meta
  name="twitter:widgets:csp"
  content="on">
