contao-article-backgrounds

This contao extension allows the backend user to set an individual background-image on every article and even add a colored article separator.

The separator/polygon can be added via a file under templates/polygons/polygon-[polygon_style].php. [polygon_style] is referring to the translation array, which at the moment includes "top", "right", "bottom", "left" and "cross". The selected color can also be picked up in the polygon templates via <?= \Input::get('color') ?>. This way e.g. an svg can easily be colored through the backend.

The extension does not deliver any CSS! So the positioning has to be done manually (See example below).

.mod_article {
    position: relative;
}

.mod_article > .article-image {
   position: absolute;
   z-index: 1;
   top: 0;
   left: 0;
   width: 100%;
   height: 100%;
   overflow: hidden
}

.mod_article > .inside {
   position: relative;
   z-index: 3;
}

.mod_article > .article-image.float-right {
   left: auto;
   right: 0;
   width: 50%
}

.mod_article > .article-image.float-left {
   left: 0;
   width: 50%
}

.mod_article > .article-image .image_container,
.mod_article > .article-image picture {
   position: absolute;
   top: 0;
   left: 0;
   width: 100%;
   height: 100%
}

.mod_article > .article-image .image_container img,
.mod_article > .article-image picture img {
   position: absolute;
   top: 50%;
   left: 50%;
   max-width: none;
   min-width: 100%;
   min-height: 100%;
   width: auto;
   height: auto;
   -webkit-transform: translate(-50%, -50%);
   transform: translate(-50%, -50%)
}
