Filmstrip Techniques in Email

Nov 29 2017 Replace:
This text has been up to date to show a fallback on Gmail on Android because it now not works on that shopper.

You’ve learn all about interactive emails. You’re considering that is actually cool, that it’s best to give it a strive. Then you definately discover on the market’s all these bizarre CSS issues you could know (as a result of Javascript isn’t supported in e mail – duh) – hidden radio buttons, the “checked” selector and “sibling” selectors. All this JUST to construct a easy interactive carousel in e mail?

Then you definately understand they’ll solely work within the iPhone e mail shopper. Wait a minute! What concerning the different half of my viewers that reads their e mail on the Gmail app on an Android cellphone? This doesn’t sound so interesting anymore.

However what if I may educate you a way to create an interactive e mail utilizing the HTML abilities you’re already acquainted with – fundamental CSS and hyperlinks. That studying the idea is so simple as visualizing pictures captured on a strip of movie by an analog digicam.

What if I advised you this methodology works on each the iPhone e mail shopper AND the Gmail app on Android as effectively. ?

Nicely let’s get began!


Windowed Named Anchors

The simplicity of the filmstrip approach lies in the usage of named anchors. Sure, these a tags containing a reputation attribute that help you leap from one a part of an e mail to the subsequent.

<a href="#foo">Click on right here</a>

<a reputation="foo"></a>
Content material right here...

By stacking blocks or frames of content material separated by named anchors and putting them inside a container that’s sized to indicate solely a single body, you possibly can show any body by referencing the anchor title in a hyperlink.

 stacking frames of content

Consider it like a strip of movie. Bear in mind these rolls of celluloid you seize photographs with earlier than the appearance of digital cameras? Nicely in our case we seize the state of every interplay as a body in a vertical strip that we selectively show within the e mail shopper.

Film strip analogy

Usually, named anchors are used to phase content material in an e mail and clicking on a hyperlink that refers to a named anchor will scroll the e-mail to the situation of the anchor. Nevertheless since these anchors are hidden inside a container, clicking on a hyperlink referring to a hidden anchor has the impact of shifting the body into view.

Surprisingly, though common named anchors don’t work within the iOS e mail shopper, they work when positioned inside a “window”.


<a href="#f1">One</a>
<a href="#f2">Two</a>
<a href="#f3">Three</a>

<div type="overflow:hidden;width:200px;top:100px;">
  <a reputation="f1"></a>
  <div type="top:100px;">Body 1</div>
  <a reputation="f2"></a>
  <div type="top:100px;">Body 2</div>
  <a reputation="f3"></a>
  <div type="top:100px;">Body 3</div>

Use ‘title’ and never ‘id’

Though the title attribute in anchors are technically deprecated in HTML5 in favor of straightforward ids, they nonetheless work in fashionable browsers. This method is not going to work within the Gmail App in case your hyperlink refers to an id as an alternative of a reputation.


Help in Electronic mail Purchasers

Replace: Sadly because of a Gmail Android replace, this system now not works on that shopper.

The next desk lists the e-mail shoppers that this system will work in. For the shoppers that don’t help this system, you’ll want to make sure you have another or fallback design to show within the different shoppers.

Right here’s the place Electronic mail on Acid turns out to be useful. Electronic mail on Acid’s e mail testing allows you to rapidly see which of the handfuls of e mail shoppers are rendering your fallback vs interactive design and if one thing is just not trying proper.

Windowed Title Anchor Help
Android 4.4 Native Shopper
AOL Mail
Apple Mail
Gmail App (Android)
Gmail POP/IMAP * (Android)
Gmail Webmail
iOS Mail
Outlook (Mac/Home windows/iOS/Android) Webmail **
Samsung Native Shopper
Yahoo! Mail App (iOS/Android)
Yahoo! Webmail**

* Gmail POP/IMAP aka Gmail Android for Non Google Accounts (GANGA)
** This method works works inconsistently in and Yahoo! Mail



Supported in main cellular e mail shoppers.

Now you’ll have the ability to design interactivity that almost all of customers of e mail shoppers on iOS and Android can see. This method works within the Gmail app for Android, Android 4.4 and Samsung native shoppers. This method received’t work within the Outlook, Yahoo! Mail and Gmail iOS apps in addition to the Gmail Android app when arrange with a non-Gmail account.


No extra lengthy chains of checked and sibling selectors to take care of, it’s simply hyperlinks and named anchors.

No CSS wanted

You continue to want CSS to type your e mail, however all of the interactivity lies utterly in HTML making the coding course of simple. Though CSS is used to detect and management when to indicate the interactive and fallback variations, that code shouldn’t have to be modified between designs.

Higher ESP help

Some e mail service suppliers (ESP) *ahem MailChimp!* strip checkbox and radio components in emails which restricted their clients’ potential to ship interactive e mail. Since this methodology solely makes use of anchors, clients of those ESPs can lastly ship interactive e mail.



There’s typically tradeoffs with regards to e mail design and that is no exception.

Lack of help in desktop and webmail.

Though common named anchors work in Gmail webmail, this system doesn’t work in Gmail webmail. Apple Mail and Outlook for Mac helps the older checkbox approach however this system received’t work in it. A observe up article will present methods to get help on the Mac utilizing a mix approach.

Not as versatile because the checkbox approach

The simplicity of the approach will also be a limitation. This filmstrip approach true to its namesake requires that every one the interactive frames be of the identical measurement. Nevertheless, you should utilize media queries to create totally different fastened dimensions primarily based on the dimensions of the display of the shopper (reminiscent of between pill and cellular).

One other function of the checkbox approach is which you can toggle the show and hiding of components reminiscent of a hamburger menu utilizing the state of the checkbox. (I’m experimenting with some methods to attain the identical impact with the filmstrip approach).

Container scrolls to the highest of window in Android

In Android shoppers (Gmail, Inbox, Samsung and Android 4.4) when the recipient triggers an anchor, the e-mail shopper will scroll the e-mail so the the brand new body is displayed proper under prime of the message window. So in case your set off hyperlinks are above the container, the recipient might want to scroll your container down every time the recipient desires to click on on a distinct hyperlink.

Within the Inbox App, the container may also be barely obscured by the toolbar when the container is shifted. The detection and fallback code we’ll use will exclude the Inbox App.

Gmail and Inbox App Frames


Tabs Instance

The next is an implementation of interactive tabs utilizing the filmstrip approach.

The tabs are styled hyperlinks that hyperlink to named anchors above the person frames. As a substitute of putting the tabs on the prime of the container, the tabs are included inside each body. This method lets you simply spotlight the energetic tab and handle the scroll problem that was talked about earlier.

Interactive Help Detection and Fallback

We wish to present a distinct block of content material for shoppers that don’t help windowed named anchors. We start by displaying the fallback by default and hiding the interactive content material.

<!--[if !mso]><!-->
<div class="interactive" type="show:none;max-height:0;overflow:hidden;">
<div class="fallback">

Then with CSS and media queries we will selectively allow interactivity just for supported shoppers. First we allow interactivity in iOS 10+ Mail shoppers utilizing a @helps approach found by Rémi Parmentier. Notice as a result of Gmail strips out type blocks containing @helps, it must be positioned in its personal <type> block.

@helps (-webkit-overflow-scrolling:contact) and (shade:#ffff) {

Subsequent we allow interactivity by concentrating on Gmail and Inbox apps in Android. We do that through the use of a Gmail concentrating on approach pioneered by Mark Robbins that solely targets the Gmail Android shopper. (I’m utilizing a shortcut that requires you to not use the <u> tag in your e mail content material).

/* This method now not works in Gmail on Android as of Nov 2017 */
div > u ~ div .interactive{
    show:block !vital;
div > u ~ div .fallback{

And at last we add the Samsung e mail shopper by concentrating on its distinctive container id of #MessageViewBody.

Verifying which model reveals up on which e mail shopper is usually a actually tedious course of. Electronic mail on Acid’s e mail testing may also help prevent hours when constructing interactive designs as you’ll have the ability to rapidly see the affect of your code modifications in over 60 totally different e mail shoppers in a single take a look at.

The ensuing interactive detection code under ought to be positioned within the <head>:

/* Utilizing @helps to ONLY goal iOS Mail 10+ */
@helps (-webkit-overflow-scrolling:contact) and (shade:#ffff) {
      show:block !vital;
   Allow for Gmail on Android
   This now not works as of Nov 2017
/*  div > u ~ div .interactive{
    show:block !vital;
  div > u ~ div .fallback{
  /* Allow for Samsung App */
  #MessageViewBody .interactive{
    show:block !vital;
  #MessageViewBody .fallback{

Including vertical house in Android

Having the interactive content material hug the highest of the window when the person interacts with it is probably not visually pleasing. One answer is to specify a margin between the named anchor and the body in order that the body seems under the toolbar. Alternatively you possibly can embody a static header on the prime of every body as a buffer.
