merge css and mdx dictionary

I have a Nokia lumia 630. I can use mdx dictionaries but I cannot use the ones that have css file. Is there any way to merge mdx dictionary and css files?
thank you

You can extract the HTML source from the MDX, and insert the CSS code into the beginning of the HTML code for each entry, and then compress it to MDX. But the generated MDX might be huge, depending on the size of CSS content.

Thank you for your response
I have downloaded OALD10.MDX from tried to open mdx file but it seems the file is protected by password so I received error. however I cannot edit it. again thank you for your attention
