difficulties switching content between different screen sizes

Having trouble with hidden-xs and visible-xs-* classes not working as expected. Even a simple code snippet like the following doesn't hide the content:

<div class="hidden-xs">
    test test test
</div>

Even when scaling down my window to the smallest size, the content remains visible. I am using the LESS compiled version without any modifications to variables.less yet. Any suggestions on how to fix this issue?

On a related note, I attempted to use the "@media (min-width: @screen-sm-min)" media query in mystyles.less, which is imported into bootstrap.less. However, my pre-processor (koala) throws an error for the variable @screen-sm-min:

NameError: variable @screen-sm-min is undefined in C:\Users\Shawn\Dropbox\GPLndscapes wordpress\less\mystyles.less:18:19
17 
18 @media (min-width: @screen-sm-min){
    .navbar .navbar-nav {

Could it be an issue with my less setup or with koala itself?

Answer №1

The problem stemmed from the LESS distribution I initially used, which was the one obtained from getbootstrap.com and did not include the necessary CSS for hidden and visible elements. Realizing this, I switched to using the bootstrap.css file from the distribution folder, which resolved the issue.

Upon examining the LESS file, I came across the following line:

@border-image: port "responsive-utilities.less";

To rectify the situation, I proceeded to add the following line:

@import "responsive-utilities.less";

I am curious about the purpose of @border-image: port and why it was used instead of a standard import. Without fully understanding its function, I am hesitant to remove it, as there may be a specific reason for its inclusion.

Regarding the @screen-sm-min issue, it appears that Koala only recognizes changes made in individual LESS files and may overlook imports into larger bootstrap files. To address this, I plan to explore other pre-processors in search of a more effective solution.
