Example problem: Configuration bootstrap_sass_starterkit.settings depends on the bootstrap_sass_starterkit extension that will not be installed after import.

Solution: delete the bootstrap_sass_starterkit.settings.yml file from the config/sync directory

and if that doesn't work just delete the files from the config directory.

CSS media queries lower px below higher or it doesn't catch it correctly in the cascade.

h1 {
font-size: 5.9vw;
}
h2 {
font-size: 3.0vh;
}
p {
font-size: 2vmin;
}

For a document that looks like this:

the style sheet looks like this:

div.container3 {
height: 10em;
position: relative } /* 1 */
div.container3 p {
margin: 0;
position: absolute; /* 2 */
top: 50%; /* 3 */
transform: translate(0, -50%) } /* 4 */
The essential rules are:


(function ($, Drupal) {
Drupal.behaviors.myModuleBehavior = {
attach: function (context, settings) {
$(window).once().on('load scroll', function () {
// ...
$('.your-class').slick({
dots: true,
infinite: true,
speed: 500,
fade: true,
cssEase: 'linear'
});
});
}
};
})(jQuery, Drupal);
