Summary
Follwing up the comments on css reference topic in blog SAPUI5 Icon Explorer for Design Studio (in standard you can atach only one), just invested 30 minutes and wrote a dynamic CSS collector SDK...
How it Works
you have more than one CSS files, eg for better structures - just to not put all parts in single one CSS. Unfortunately, in standard you can attach only one CSS to the application. Then use the CUSTOMCSSCOLLECTOR:
Example
in my example I have 4 CSS, one static (pink) and 3 dynamic (red, blue, green)
whcih I want to load dynamically, based on some parameters, like in this case an URL parameter XCOLOR:
&XCOLOR=BLUE
leads to the script onStartup:
APPLICATION.createInfoMessage("Color:; " + XCOLOR);
if(XCOLOR == "RED") { CUSTOMCSSCOLLECTOR_1.addCss("RED", "custom_red.css");
}
if(XCOLOR == "GREEN") { CUSTOMCSSCOLLECTOR_1.addCss("RED", "custom_green.css");
}
if(XCOLOR == "BLUE") { CUSTOMCSSCOLLECTOR_1.addCss("RED", "custom_blue.css");
}
// always pink
CUSTOMCSSCOLLECTOR_1.addCss("PINK", "custom_pink.css");
// another condition - exchange the RED by other file
if(XEXCHANGE) { CUSTOMCSSCOLLECTOR_1.updateCss("RED", "custom_black.css");
}and then, you can load more than one CSS (eg. blue and pink) with some different parts of the css definitions.
content of custom_blue.css:
.special-background {
background-color: blue !important;
}
content of custom_red.css:
.special-background {
background-color: red !important;
}
By this, you can not only dynamically create your css by bundling it inmore files, but you can dynamically disable, exchange some or enable again...

Scripting Functions
| Scripts | Short Description |
|---|---|
void addCss ( /**CSS Key (must be unique)*/String elementKey, /**CSS Url*/String elementUrl, /**If true (default) it will be loaded*/optional boolean isActive) | add a css which should be dynamically attached |
void updateCss ( /**CSS Key (must be unique)*/String elementKey, /**CSS Url*/optional String elementUrl, /**If true (default) it will be loaded*/optional boolean isActive) | update the definition (if you want to disable, just place updateCss("KEY", /*empty as no change*/ "", false); |
