Right here’s a good spot that electronic mail builders will probably be very accustomed to. You get an electronic mail marketing campaign mockup from a designer and so as to make it each purposeful and accessible, you have to use overlapping parts.
As builders, it’s our job to make the e-mail look as near the proposed design as doable. However coding overlapping parts is far more difficult in an HTML electronic mail when in comparison with net improvement. Nevertheless… it’s not not possible.
This time on Notes from the Dev: Video Version, we’re going to discover a method for coding overlapping parts in electronic mail utilizing what’s often known as fake absolute positioning. My visitor for this episode is Niven Ranchhod from mailix by Mayoris AG. He’s going to indicate us this methodology in motion.
Try the video beneath to see how Niven makes use of fake absolute positioning to “trick” rendering engines so he can construct emails with separate, but overlapping textual content, background, and graphics.
What’s absolute place in CSS?
The CSS place property is used to position objects subsequent to or on prime of one another in addition to management their placement in different methods. There are 5 several types of CSS positioning (Discover out extra from CSStricks.com):
- Absolute: Permits a component to be positioned anyplace you need.
- Fastened: Retains a component within the viewport as you scroll.
- Relative: Makes use of prime, left, backside, and proper to regulate a component’s place relative to itself.
- Static: The default CSS place for any factor.
- Sticky: A mix of relative and glued that retains a component in view till you scroll past a sure level (outdoors a dad or mum factor).
So, place:absolute is fairly highly effective as a result of it offers the coder lots of flexibility by way of the place parts get positioned. There’s only one huge downside for electronic mail builders…
Why you have to “pretend it”
As Can I E mail exhibits us, the place property doesn’t have widespread help in electronic mail (in any respect).
The approach we’re speaking about at this time is known as fake absolute positioning as a result of we’re utilizing a hack to get electronic mail shopper rendering engines to deal with parts in a manner that’s much like place:absolute. Pretend it ‘til you make it, proper?
The primary individuals to determine fake absolute positioning for electronic mail improvement had been Mark Robbins and Steven Sayo. You possibly can take a look at Mark’s weblog submit, and Steven’s article on Medium to seek out out extra.
However first, let’s discover how Niven makes use of the approach. You too can discover all of this in an article he wrote for mailix by Mayoris AG.
How you can obtain overlapping parts in emails
In his big-picture clarification of fake absolute positioning, Niven instructed us that we’re basically fooling the rendering engines by setting both max-height or max-width to zero and adjusting these values to get the exact place wanted. Adjusting the width is definitely a brand new methodology that Niven tailored from Mark and Steven’s authentic method.
Utilizing fake absolute positioning, the factor (or block) you add beneath strikes into that house to fill the void, and the primary block finally ends up displaying on prime of the factor you’ve coded beneath it. As Niven confirmed us within the video, you should use this trick to reposition a component from the highest, backside, left, or proper.
Right here’s a have a look at the overlapping parts Niven wanted to code into an electronic mail and the way it seemed earlier than he utilized fake absolute positioning:
The unique design
Earlier than fake absolute positioning
Now, you would possibly have a look at this and surprise why it couldn’t be a single, clickable graphic within the electronic mail. Or possibly you assume picture splicing within the electronic mail can be an appropriate method. There are a couple of the explanation why one graphic is a nasty thought.
- You want dwell textual content: Since this graphic features a call-to-action (CTA) button, any subscriber with picture downloading turned off received’t see it in any respect. That goes for the textual content too. They merely can’t learn it and received’t click on the button. Don’t neglect, photos are turned off by default in Outlook.
- It’s inaccessible: In case you aren’t utilizing dwell textual content, display screen studying software program received’t have the ability to interpret the e-mail copy for individuals with imaginative and prescient impairments. Meaning these subscribers received’t get the message and might’t have interaction with the e-mail both.
- It might not be mobile-friendly: In case you splice a picture like this and put it collectively like a puzzle, you can have responsiveness points. The items could find yourself stacking on cell units, leaving an unpleasant mess.
Niven identified that you can additionally mix the photograph and the background to make a single background picture with dwell textual content on prime. However the situation there may be you’d want to make use of a number of media queries to get the textual content and background to resize precisely for various display screen sizes.
That will require lots of additional code, and Niven wanted to maintain this electronic mail easy so a Mailix shopper may replace parts for various manufacturers. Plus, there have been darkish mode challenges to think about as properly. So, fake absolute positioning gives an excellent various resolution.
Constructing an electronic mail block with overlapping parts
Under, you’ll see how and the place the weather on this mixed block overlay. Niven knew it could be tough. The picture must line up with the underside of the background tile whereas extending past the highest. The textual content wants to sit down on prime of the background whereas overlapping the picture, and there must be ample padding round all parts.
In Niven’s electronic mail code, the textual content and button are mixed with the picture to create a content material block that’s wrapped in a <div> tag. The textual content and button are in a single column and the picture is in one other. The background is a VML that’s in a separate block, which wanted to maneuver up and beneath the content material block.
To make that occur, Niven units the max-height of the <div> wrapper for the content material block to zero.
<div class="content-block" type="max-height:0;">As you’ll see within the video, the background VML strikes up and the textual content and picture are overlayed on prime of it. Nonetheless, it’s not fairly excellent. Niven needed to alter issues to get them in alignment and match the unique design. To do this, he merely experimented till he discovered that setting the max-height to twenty pixels fastened it for this specific design.
<div class="content-block" type="max-height:20px;">When it got here to adjusting the content material horizontally, Niven used the identical idea however utilized it to the max-width.He then used a bigger inside width for textual content in order that it pushed the content material out and created an overlap.
As Niven explains within the video, he’s form of mendacity within the code so as to transfer parts the place he wants them to be positioned:
“All it’s doing is tricking the rendering engine by saying, ‘That is how huge I’m alleged to be: 225 pixels huge.’ After which, inside I’m truly 600 pixels huge. However I’m not going to inform the rendering engine that.”

When utilizing this methodology for horizontal positioning in your electronic mail code, you’ll need to experiment to seek out out what fake width will get overlapping parts to align the way in which your design requires.
Addressing coding challenges for Outlook
As each electronic mail developer is aware of, lots of additional work goes into making issues work in Outlook. This time, we have to add some conditional CSS statements to focus on Outlook for Home windows desktop as a result of it doesn’t help nested VMLs.
However guess what? On this state of affairs, we are able to use place: absolute with out faking it as a result of utilizing absolute positioning with VMLs is supported in Outlook. Though, Niven instructed us he believes that is solely true in the case of VML.
Niven used a <v:rect> factor together with place: absolute to maneuver the background tile up. He then used one other <v:rect> to attain the intersection of the textual content and picture.
As with the max-height adjustment, he wanted to make some tweaks to the conditional code as properly. It turned out that the 20 pixels wanted to align the picture accurately in different shoppers was -16 pixels utilizing absolution positioning for Outlook. He then did the identical for the width.
<v:rect stroked="f" stuffed="false" type="place:absolute; prime:-16px; left:-15px; width:203pt;">
<v:textbox inset="0,0,0,0" type="mso-fit-shape-to-text:true;">Once more, that is one thing Niven labored out by way of trial and error, and also you’d must do the identical together with your code.
There’s one other solution to work with Outlook and VMLs that Steven Sayo describes in Half 2 of his fake absolute positioning suggestions. It includes utilizing <v:textbox> with the type mso-fit-shape-to-text as a substitute of adjusting the peak of the <v:rect>.
The entire code
Right here’s the complete view of Niven’s electronic mail code. It’s received every little thing he used to attain each vertical and horizontal fake absolute positioning:
One factor in regards to the design that wasn’t achieved was rounded corners for Outlook. Niven and I each agreed on how that’s a progressive enhancement that will require an excessive amount of time, additional work, and extra code to make it well worth the effort. The excellent news is that almost all of subscribers are going to see an electronic mail that nearly completely displays the unique design idea.
Testing how overlapping parts render is necessary. So, in case you attempt fake absolute positioning, be sure you use an answer like E mail on Acid’s previews to see how your code works on greater than 90 shoppers and units.
