    Give priority to a CSS file

    Dear users,

    I have a HTML page like this:

    HTML Code:
    <link rel="stylesheet" type="text/css" href="styles.css">
    <link rel="stylesheet" type="text/css" href="themes.css">
    Now I want all the statements written in themes.css must overwrite the statements in styles.css

    I don't want to use !important every statement in themes.css

    Is there a fast way?

    Then swap them around... pages load in the order in which the statements are encountered and whats more, if you already have a style sheet set a page up, what the point of over writing the styles? Just load up the styles you want and no messing around wasting peoples data allowances and bandwidth.

    If you can't think outside the box, you will be trapped forever with no escape...

    So, in the example I have written themes.css, but it is a dynamic CSS generated by php and mysql, so it will be "user.php?what=his_style".

    Then there is a general CSS for all users, but there is also a specific CSS for the user (not all users), and I need to overwrite the general styles with the user's style.

    So, we return from the begin.

    How can I do?

    If you have a user account who has been allowed their own page theme, then you would store that information in a database as a CSS string that you write in with PHP to the page rather than wasting time loading a theme to be written over immediately, I assume the person has to login to their account, thats how you would then serve up their theme.

    I didn't understand very well what you written, but I want to know if I can do what I asked in first post.

    Or if there is a similar fix, I don't want to edit PHP files.

    There are several rules for the priority of CSS properties. Most important:
    1. The last assignment will overwrite all previous ones, i. e. assignments in your second file will overwrite those in the first file.
    2. Assignments on a selector being more specific will override assignments on a selector being less specific, i. e.
    div.theclass{background-color: red} will override div{background-color:white}.
    If div.theclass{background-color:white} is defined in your first file it will have priority and will not be overridden by div{background-color:white} in the second file.

    Yes, I know.

    I read this document: https://www.w3.org/wiki/CSS/Training...el_of_selector

    Unfortunately, in the second file (themes.css) I defined the selectors in order to have a priority level lower than the first file (styles.css), and I can't change them for different reasons.

    So when I see the window inspector, I can see the "themes.css" rules overwritten by "styles.css" rules.

    This is the problem.

    I want the "themes.css" will overwrite "styles.css" without writing !important at all the statements in themes.css

    Is there a solution?

    I don't know any solution for this problem. The only solution I know about is deactivating the complete styles.css file. However this would require defining all rules completely in the second file again instead of overwriting a few.
