PreMailer.Net
C# Library for moving CSS to inline style attributes, to gain maximum E-mail client compatibility.
Usage
Static method on PreMailer
class
string htmlSource = File.ReadAllText(@"C:\Workspace\testmail.html");
var result = PreMailer.MoveCssInline(htmlSource);
result.Html // Resultant HTML, with CSS in-lined.
result.Warnings // string[] of any warnings that occurred during processing.
Set up PreMailer
instance
string htmlSource = File.ReadAllText(@"C:\Workspace\testmail.html");
var pm = new PreMailer(htmlSource);
pm.AddAnalyticsTags(source, medium, campaign, content, domain = null); // Optional to add analytics tags
var result = pm.MoveCssInline(...);
result.Html // Resultant HTML, with CSS in-lined.
result.Warnings // string[] of any warnings that occurred during processing.
Options
The following options can be passed to the PreMailer.MoveCssInline
method to configure it's behaviour:
baseUri(Uri = null)
- Base URL to apply tolink
elements withhref
values ending with.css
.removeStyleElements(bool = false)
- Removes elements that were used to source CSS (currently, onlystyle
is supported).ignoreElements(string = null)
- CSS selector of element(s) not to inline. Useful for mobile styles (see below).css(string = null)
- A string containing a style-sheet for inlining.stripIdAndClassAttributes(bool = false)
- True to strip ID and class attributes.removeComments(bool = false)
- True to remove comments, false to leave them intact.
External style sheets
Sometimes it's handy to reference external style sheets with a <link href="..." />
element. PreMailer will download and use external style sheets as long as the value of href
ends with .css
.
Both absolute and relative URLs are supported. If the URL is relative, you must specify the baseUri
parameter in either the constructor, or when calling the static MoveCssInline
method.
<link />
elements that match the ignoreElements
selector won't be downloaded.
Media queries
If you want to apply mobile styles to your e-mail, you should put your
mobile specific styles in its own style
block that targets the appropriate devices using media queries.
But since you cannot know by the time of sending an e-mail whether or not it will be viewed on a mobile device, the style
block that targets mobile devices should not be inlined!
To ignore a style
block, you need to specify an ignore selector when calling the MoveCssInline
method, like this:
var result = PreMailer.MoveCssInline(input, false, ignoreElements: "#ignore");
And your mobile specific style
block should have an ID of ignore
:
<style type="text/css" id="ignore">.target { width: 1337px; }</style>
Premailer specific CSS becomes HTML attributes
Premailer looks for the use of CSS attributes prefixed with -premailer
and will proxy the value through to the DOM element as an attribute.
For example
table {
-premailer-cellspacing: 5;
-premailer-width: 500;
}
will make a table
element render as
<table cellspacing="5" width="500">
Custom DOM Processing
using(var pm = new PreMailer(html)){
var document = pm.Document;
// use AngleSharp to process document before moving css inline ...
var result = pm.MoveCssInline();
}
Notes
- Pseudo classes/elements which not supported by external dependencies, or doesn't make sense in email, will be ignored and logged to the
InlineResult.Warnings
collection.
