E-mail on Acid despatched a enjoyable interactive e-mail for the 4th of July that includes a “select your journey” format the place the reader had a alternative of sending an e-mail with out testing on E-mail on Acid or after testing. There have been a number of methods within the e-mail comparable to a ticking clock, however on the core the e-mail makes use of a “quiz format” the place successive pages are displayed based mostly on a number of choices from a earlier web page inside an e-mail. Such a setup can accommodate a mess of different interactive e-mail situations that we are going to go into element later, comparable to product itemizing filters, video games, tutorials and carousels.
Take a look at the 4th of July e-mail right here
(view in a Webkit browser like Chrome or Safari)
This text will go into the way to implement a easy model of that approach in e-mail. The e-mail purchasers that this method will work with embody iOS Mail, Apple Mail and Samsung Mail. Different purchasers will probably be proven a fallback model.
Displaying Pages Utilizing Radio Buttons
The center of the approach includes a set of radio inputs, one for every web page in addition to a set of pages and having every web page solely be seen when a corresponding radio enter is checked. Naturally the primary radio enter similar to the primary web page will initially be checked.
The next code demonstrates the idea of toggling between two pages:
<type>
.page1,.page2{
show:none;
}
#radio1:checked ~ .container .page1,
#radio2:checked ~ .container .page2{
show:block;
}
</type>
<enter title=alternative kind=radio id=radio1 checked>
<enter title=alternative kind=radio id=radio2>
<div class="container">
<div class="page1">Web page 1
<label for="radio2">[next]</label></div>
<div class="page2">Web page 2
<label for="radio1">[back]</label></div>
</div>
Our instance demonstrates a 3 stage setup with 4 pages
The Begin button in Web page 1 is a label that has the “for” attribute focused to the id of the radio enter of Web page 2. Then Web page 2’s two buttons are labels focusing on the radio inputs of Web page 3A and 3B respectively. Then lastly Web page 3A and 3B’s Again button targets Web page 2’s radio enter and the Begin Once more button targets Web page 1’s radio enter.
Right here is the Codepen for the setup.
Fallback for non interactive purchasers
We need to be certain that the interactive half solely show for purchasers that help animations and the :checked selector. Following the methods outlined on this article, we use the -webkit-min-device-pixel-ratio media question and checked checkbox strategies.
Moreover though AOL Mail help checkboxes, it doesn’t help the “for” attribute in labels that we use in our instance so we additionally want to indicate the fallback for AOL Mail.
The next code exhibits the code with fallback.
<type>
@media display screen and (-webkit-min-device-pixel-ratio: 0) {
.cbox-support:checked ~ div .fallback {
show:none;
}
.cbox-support:checked ~ div .interactive{
show:block!essential;
max-height:none!essential;
}
/*
Selective blocking for non supported purchasers.
- AOL doesn't help the for="" attribute in labels
*/
enter[class~="aolmail_cbox-support"]:checked ~ div .fallback{
show:block!essential;
}
enter[class~="aolmail_cbox-support"]:checked ~ div .interactive{
show:none !essential;
}
}
</type>
<enter kind=checkbox class="cbox-support" checked>
<div>
<!-- FALLBACK -->
<div class="fallback">
Fallback content material
</div>
<!-- finish of FALLBACK -->
<!-- INTERACTIVE/KINETIC -->
<!--[if !mso]><!-- -->
<div class="interactive" type="show:none;max-height:0;overflow:hidden;">
Interactive content material
</div>
<!--<![endif]-->
<!-- Finish of Interactive/Kinetic -->
</div>Absolute positioning and the Samsung consumer
In contrast to the 4th of July e-mail instance, this interactive quiz instance doesn’t use absolute positioning regardless that it’s supported by the iOS mail consumer. The explanation for that is that we wish to help the Samsung e-mail consumer that doesn’t help absolute positioning. If you wish to use absolute positioning, then you definately’d want so as to add the next code to disable the interactivity within the Samsung e-mail consumer.
#MessageViewBody .cbox-support:checked ~ div .fallback{
show:block!essential;
}
#MessageViewBody .cbox-support:checked ~ div .interactive{
show:none !essential;
}
Transitioning between pages
It is likely to be extra visually pleasing to have the subsequent web page fade in as a substitute of immediately seem. This may be achieved utilizing transitions or animation. To attain that, now we have the web page begin with opacity: 0 when initially displayed after which animate to opacity: 1. That is demonstrated with the next code.
#cbox-1:checked ~ * .interactive .page1,
#cbox-2:checked ~ * .interactive .page2,
#cbox-3a:checked ~ * .interactive .page3a,
#cbox-3b:checked ~ * .interactive .page3b{
show:block;
-webkit-animation: fadein 0.5s linear;
}
@-webkit-keyframes fadein{
0%,45%{ opacity:0; }
100%{ opacity:1; }
}Different max-height approach
Nevertheless what about having the unique web page fade out earlier than the subsequent web page fades in? Right here issues get a bit extra sophisticated. Since we’re utilizing show:block and show:none, the second the checkbox for the unique web page is unchecked, show:none kicks in and we aren’t allowed time to vary the opacity. Nevertheless we are able to carry out a fade-out approach by utilizing max-height. It is because, not like show, you’ll be able to delay the max-height change by incorporating it as a part of the transition animation. Utilizing max-height is way more concerned, however permits you the chance to implement “transition out” results.
Right here’s a partial CSS instance.
.web page{
text-align:middle;
overflow:hidden;
max-height:0px;
}
#cbox-1:checked ~ * .interactive .page1,
#cbox-2:checked ~ * .interactive .page2,
#cbox-3a:checked ~ * .interactive .page3a,
#cbox-3b:checked ~ * .interactive .page3b{
max-height:none;
-webkit-animation: fadein 0.5s linear;
}
#cbox-1:not(:checked) ~ * .interactive .page1,
#cbox-2:not(:checked) ~ * .interactive .page2,
#cbox-3a:not(:checked) ~ * .interactive .page3a,
#cbox-3b:not(:checked) ~ * .interactive .page3b{
max-height:0px;
-webkit-animation: fadeout 0.5s linear;
}
@-webkit-keyframes fadein{
0%,49%{ opacity:0; max-height:0px;}
50%{ opacity:0; max-height:none;}
100%{ opacity:1; max-height:none;}
}
@-webkit-keyframes fadeout{
0%{ opacity:1; max-height:none;}
49%{ opacity:0; max-height:none;}
50%,100%{ opacity:0; max-height:0px;}
}
Scrolling up on transition (iOS)
The quiz approach works greatest if the content material suits throughout the web page with out scrolling. The issue with longer content material is that if the button requires scrolling, the subsequent web page is displayed already scrolled down, so that you don’t see the content material on the prime and have to scroll again up which generally is a unhealthy expertise.
On iOS nevertheless, there’s a method you should utilize to “scroll up” to the subsequent web page. Its not a foolproof methodology and requires some trial and error, however the approach includes shrinking the container to pressure the consumer to scroll the e-mail again up. This method causes Apple Mail to scroll up and again down, so we have to isolate it utilizing a media question to make sure its solely enabled in iOS.
@media (max-device-width:600px){
#cbox-1:checked ~ * .interactive .page1,
#cbox-2:checked ~ * .interactive .page2,
#cbox-3a:checked ~ * .interactive .page3a,
#cbox-3b:checked ~ * .interactive .page3b{
-webkit-animation: fadein-scrollup 1s linear;
animation: fadein-scrollup 1s linear;
}
}
@-webkit-keyframes fadein-scrollup {
0% { opacity:0; max-height:1000px; }
40%{ max-height:450px; }
45%{ opacity:0; max-height:none; }
100%{ opacity:1; }
}
@keyframes fadein-scrollup {
0% { opacity:0; max-height:1000px; }
40%{ max-height:450px; }
45%{ opacity:0; max-height:none; }
100%{ opacity:1; }
}The Last Code
Right here’s the Codepen for the fundamental instance.
Right here’s the Codepen utilizing the max-height approach.
Right here’s the Codepen with the “scroll up” approach.
Purposes of this method
There are fairly a number of use instances for this method:
