To accurately determine the width of a div element, it is essential to include the web browser width in the CSS

Is there a way to calculate the width of a div named incontent in the index.php file, based on the width of the browser screen and other data? I have heard about using JavaScript to get the screen width, but the challenge lies in the fact that the styling is defined in an external stylesheet called style.css. I’m not sure if it’s possible to use a JavaScript variable in the stylesheet definition without resorting to CSS media queries. Can anyone provide suggestions on how to resolve this issue? Thanks

Answer №1

If you want to achieve this, you will need to utilize Javascript or CSS media queries. Given your preference against using media queries, it seems like the best solution would be to implement the necessary Javascript code to accomplish the task.

It's worth noting that Javascript variables cannot be accessed within CSS files, and CSS itself is primarily focused on styling rather than functionality.

While I'm unsure of your reasoning for avoiding media queries, they are typically the recommended approach for achieving a responsive design. Alternatively, utilizing percentages could also be effective in creating a responsive layout.

Answer №2

To determine the screen width, you can use:

let screenWidth = window.innerWidth

You can then set this width to any element using:

document.getElementById('element_id').style.width = screenWidth + 'px'

If you need further clarification or assistance, feel free to ask!

Answer №3

If you are looking to incorporate JavaScript into your project, JQuery is a great option to consider.

To obtain the screen width, you can use the width() method:

$(window).width();

If you need to retrieve the width of a specific div element, you can utilize innerWidth() to get the inner width excluding padding:

$("div#divId").innerWidth();

Alternatively, you can use outerWidth() to include padding and border (and margin if specified).

$("div#divId").outerWidth(); /* without margin */
$("div#divId").outerWidth(true); /* with margin */
