Can you manipulate a media query breakpoint to be fixed at a certain point?

Question

Can you manipulate a media query breakpoint to be fixed at a certain point?

Imagine having a CSS file with the following styles:

@media screen and (min-width: 640px) {
 ...styles are defined here
}

If you wish to enforce the page to follow the specific breakpoint's styles, essentially ensuring that "the width is always > 640px" regardless of the actual window size, how can this be achieved using HTML, CSS, or JavaScript?

You don't have permission to modify the original stylesheet, but you can add an additional stylesheet or run custom code. However, copying and pasting all the styles for this breakpoint is not ideal if there is another solution available.

Answer №1

To solve this issue, one approach could involve duplicating the media query rules for a specific CSS style sheet using JavaScript to match certain condition text. Here is an example of how this could be achieved:

const styles = [];

for (const CSSStyleSheet of document.styleSheets)
    for (const rule of CSSStyleSheet.cssRules)
        if (rule instanceof CSSMediaRule &&
            rule.conditionText === 'screen and (min-width: 640px)') {
            for (const r of rule.cssRules)
                styles.push([CSSStyleSheet, r.cssText]);
        }

styles.forEach(([style, rule]) => style.insertRule(rule));
