Inline CSS in HTML Emails: Enhancing Compatibility and Styling
Web pages contain various properties and classes that are supposed to be updated, and the same is to be reflected in all the rest of the future pages. But, in case of emails, they are specific to one particular email template. Hence, it’s quite preferable to keep them inline.
As we know, email coding comprises of CSS and HTML, and CSS styles fall mainly into 3 categories – External, Internal and Inline styles. While web browsers and web pages are indulged with external CSS, Emails uses inline CSS.
Inline CSS vs. Internal/External CSS
Technologies like LESS CSS, SAAS, etc. are widely used nowadays in web page development. Also, there are many email development companies that use SAAS with Zurb framework but then what to choose depends upon the scenario of what is actually needed.
Suppose, one is engaged into building of email template to be used for multiple email campaigns or clients. In that case, the html email code is to be edited on regular basis for certain and especially when the framework is to be carried out with CSS in HTML emails. Here, the best thing that can be used is internal CSS as it provides much ease when it comes to code editing.
But, if the email template is for one time campaign than inline CSS would surely be an ideal choice. If you are a web developer who is looking forward to email coding, than you can surely opt for internal CSS and thereafter use inliner tool for the same.
Why Inline CSS in Email?
Email coding comprises of CSS and HTML. Inline styles move the CSS and the associated formatting instructions from the very side block of the email to the body of HTML. Most of the email clients today prefer the CSS to be inline. And, most of the ESPs like Mailchimp or Campaign Monitor will inline the CSS first and once inlined it would then distribute to the subscribers.
Though the best methodology to code the email might be different but the number of key design fundamental of email haven’t been amended. In last few years, we have witnessed many transformations in the versions of Hotmail, Google, and Yahoo!
In order to acquire design consistency across various email environments, CSS in inline form is the best option one can opt for. If you are looking for best support in Gmail and Outlook 2007, Inline CSS turns out to be the best option.
Moreover, inline CSS is safest when it comes to ensuring the rendering of compatibility across the different email clients. One of the greatest advantages delivered by inline styles is its direct application to HTML elements. It is directly applied to the elements of HTML email templates in each of the lines of HTML.
