What types of HTML/CSS are the most reliable and which are not recommended?
Please us the following guidelines when preparing the Freeform HTML: • CSS should be embedded in the BODY tag, rather than the HEAD tag. External CSS file references is not recommended due to webmail (Hotmail, Yahoo, etc.) email client restrictions. • Do not add style to the BODY tag, some webmail clients will ignore body attributes/styles. • Background colors/images should be applied to container tables/divs, rather than the BODY. • Do not rely on CSS inheritance. Write your CSS specifically (i.e. element#idname p {} as opposed to just p {}. • Text links need explicit inline styling to render as desired in most webmail clients. • Avoid commenting within the CSS, this could cause issues with webmail clients.
