Styling Custom Components with Oracle JET SCSS Variables

In my post Extending Oracle JET Components Through Custom Bindings, I used CSS to move the ojInputText border from the input element to the ojInputText "root" element. One of my readers commented on my improper use of color values instead of SCSS variables. Great point! Oracle JET includes SCSS theme variables for color and style. Since my goal was to maintain the delivered Oracle JET styling, it is better to use the Oracle declared SCSS theme variables. Here is what that prior example would look like if I used Oracle JET's theme-specific SCSS variables:

// following three lines taken from oj-alta.scss
@import "../bower_components/oraclejet/dist/scss/alta/oj.alta.variables";
// note: this generates a very large css file and takes a while to compile.
// if you are just interested in the variables, you can cheat and comment out
// these two imports
@import "../bower_components/oraclejet/dist/scss/3rdparty/normalize/normalize";
@import "../bower_components/oraclejet/dist/scss/alta/oj.alta.widgets";

.content-container {
  margin: 10px;

/* icon CSS here */
.birthday-input:after {
    font: normal normal normal 14px/1 FontAwesome;
    content: "\f1fd";
    margin: 0 10px;

.birthday-input input {
    border: none;
    flex: 1;

.oj-inputtext.birthday-input {
    display: flex;
    flex-flow: row nowrap;
    align-items: center;
    background-color: $background3Color;
    border: 1px solid $border4Color;

Notice the import at the top of this code fragment. This is a relative path pointing to the Oracle JET SCSS files within the bower install directory. In my case I store scss in a "styles" subfolder of the root project folder, making this path a relative path from ./styles to ./bower_componnets.

This solution assumes that you have your project configured for SCSS (grunt tasks, etc). Be aware that SCSS is not part of the Yeoman generated Oracle JET build script. You can learn more about Oracle JET and SCSS in the document Customizing an Oracle JET Theme Using Sass

Unfortunately, I can't exactly show this in a jsFiddle because the SCSS in jsFiddle doesn't appear to support remote scss partials. I can, however, paste in the relevant oj.alta.variables and pretend that I am importing the real Alta variables. In the sample below, instead of modifying one of my prior examples, this is another iteration of the "ojInputText with animated clear button" that has better support for accessibility (you can now tab to the delete button if it is visible).
