Avoiding clashes between CSS styles in web applications

As I work on developing a web application that can be embedded on external websites, one of the challenges I am facing involves constructing dialogues with their own unique stylesheets. This could potentially lead to conflicts if both my dialogue container and the host website's content share the same class name such as .container.

I have considered changing all my classes to something like 

.appname-container</code, but I prefer to find a simpler solution before taking that step. Is there an easier way to avoid unexpected clashes with stylesheets from external sources over which I have no control?</p>

<p><strong>Edit</strong>: Since my web app wraps around a <code><video>
element, using <iframe>s may not be a feasible option.

Answer №1

Utilizing iframes can help prevent conflicts with other applications. Implementing a unique namespace for your css will prevent interference with styling from external sources, but without the use of an iframe, your content may still be affected by existing styles. For straightforward content, you might be able to mitigate this issue by implementing some resets.

Answer №2

Going forward, we can look forward to utilizing the CSS3 all property for this purpose:

However, it appears that this feature is not yet fully available for use. (I did not find any mention of it on Caniuse yet.)
