Can we create and use custom themes in Netsuite SPA?

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that NetSuite does not natively support the creation and use of custom themes in SuiteCommerce Advanced (SCA) or SuiteBuilder. The platform primarily uses its own themes, designs, and layouts. While there is a feature called "Advanced Site Customization" that allows for some level of customization beyond the basic NetSuite defaults, it's not clear whether this feature is part of SuiteCommerce Advanced or if it can be provisioned to SuiteBuilder. In terms of UI customization, it seems that NetSuite does not allow extensive changes. For instance, the colors of buttons cannot be customized, and CSS positioning on forms is not supported unless you use an Inline HTML field/Rich text field. However, there are some workarounds suggested in the conversations. One is to use a browser extension like Stylish to roll out a custom stylesheet. Another is to use a template engine like Pug to compile template files into HTML as part of a build step, which can then be deployed/uploaded to NetSuite. Please note that these workarounds may not be officially supported by NetSuite and could potentially lead to issues. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******

Not SCA, in SPA i.e. Single Page Application
