Preventing external HTML code from conflicting with CSS styles

Question

Preventing external HTML code from conflicting with CSS styles

One of the challenges I'm facing on my website is displaying HTML email content.

Some of the emails contain CSS that messes up my site layout, causing certain elements to overlap each other. For example, a toolbar at the top of the page might cover important header information from the email.

Is there a way to create a div where I can place the HTML email and control its layout so it doesn't interfere with anything else on the page?

It's worth mentioning that I have the HTML content as 'text' instead of linking to an external website. (In this case, it's returned from an API, but similar restrictions apply)

%iframe{srccode: @mail.html}

However, simply using this code results in a blank iframe

Answer №1

One way to include your mail is by using an IFrame, like this:

<iframe src="http://www.example.com"></iframe>

By doing this, you can keep the styles separate.

To customize the IFrame, you can check out this link for options.

If you're using html as text instead of linking to an existing page, you can do it like this:

%iframe{srcdoc: "#{@mail.html}"} #for rails / haml

Alternatively, you can use this code:

<iframe srcdoc="<your html as text>"></iframe>

You have the option to use scoped styling:

<div>
  <style scoped>
    h1 { color: FireBrick;   }
    p  { color: SaddleBrown; }
  </style>
  <h1>This is an H1 in a scoped div. It will always be styled as "FireBrick".</h1>
  <p>This is a paragraph in a scoped div. The text will be "SaddleBrown".</p>
</div>

<p>Another paragraph here, unaffected by the scoped styles and will remain black.</p>

It is important to note that this feature is experimental and not widely supported by browsers as of 2015. Currently, only Firefox version 21.0 and above support this feature. (more info @ w3school.com)

In the response provided by Dave above

<iframe src="http://www.w3schools.com"></iframe>

is an effective method for linking to an external website or a page that is in HTML format.

If you are using HTML as plain text (instead of linking to an existing page):

%iframe{srcdoc: "#{@mail.html}"} #for rails / haml

or

<iframe srcdoc="<your html content>"></iframe>

Customizing the iframe according to your needs will get the job done efficiently.
