Color adjustment of text on different themes

Color adjustment of text on different themes

Work on maintaining a system that could only be displayed with the white background, and we recently adopted the possibility for the user to choose the dark background.

Some text fields are saved with formatting in the database, so if the color of the formatted text is black the display is compromised.

Is there any way to improve the display of these black-colored formatted texts on dark background?

I’m looking for a javascript or Asp.net-compatible library to match the colors.

Edit

Here is an example of how data is saved to the database:

Colors, font sizes, among others, deals with CSS

You could ask the question some examples of formatting that comes from the database for a better analysis.

You can change the colors/fonts of the letters by css.

In your js code, when the user calls the function that changes the background color, the commands for changing the theme will be executed, in this same function put css commands to change the color of the letters.

Or if you don’t want to do this, you can change the default font color to a gray, which would match the black and white, highlighting both!

Hug, any doubt I’m available!

EDITED ANSWER

I do believe that most of the visual things you’re facing can be solved with CSS and some treatments. For example when the user switches to the dark background to call some class that changes the formatting of data inputs, within that class (in CSS) all elements must have the

!important

because this command will ignore old rules and run over them for example my code has command of Style inline in HTML and my CSS has the ! Important look at the result:

    function changeclass() {

    var NAME = document.getElementById("change")

    NAME.classList.toggle('bgEscuro');

    }

    .bgEscuro {
        background-color: black !important;
        color: grey !important;
    }

    <html>
    <head>

    </head>
    <body>

    <h1 id="change" style="background-color: white; color: black">Hello World!</h1>

    <button type="button" onClick="changeclass()">Click Me!</button>


    </body>
    </html>
