Customizing text documents within an iframe using CSS from the parent page

My HTML page consists of multiple iframes, each linking to a text file on the same domain.

I have done some research on how iframes behave when they point to an HTML file, but I haven't found much information on what happens when they link to a text file. Also, it's not possible to add styling directly inside the text files themselves.

The interesting part is that the text content of the iframe inherits the background color of the parent element, but not the text color.

When I apply the following CSS in the parent HTML document, the background color of the iframe content changes accordingly:

iframe
{
    background-color: black;
}

However, when I try to change the text color of the iframe content using the code below, it doesn't work:

iframe
{
    color: white;
}

Why does this happen?

Answer №1

If the document loaded into an iframe does not have a background-color specified, it will default to transparent. This means that the background-color you see is actually that of the iframe itself because CSS only applies to the iframe and not its content.

Therefore, if you want to edit the text color within an iframe, you will need to use an alternative method. This thread provides some suggestions:

How can I apply CSS to an iframe?

Unfortunately, there is no official way to directly modify the content within an iframe, so you may be limited to using workaround solutions.

Answer №2

I have created a personalized file explorer that can operate independently or within an iframe. It seamlessly integrates with the rest of the website when displayed in an iframe. By clicking on a TXT file, it opens up even though the site has dark backgrounds. To avoid adjusting the text color to be visible on the dark background, I decided to have the links open in a new tab instead. This not only resolves the issue of dark text on a dark background but also enhances the user experience.

It may be beneficial to explore alternative solutions without changing the text color.
