But, suppose I want to have that underline to become thicker instead of disappearing. That will require an advanced, super-secret CSS technique. To make it work, we will utilize box-shadow.
In the world of cascading style sheets, the box-shadow property adds a shadow effect around any HTML element. The shadow is described by its offsets, relative to the element. Leveraging this, we can create a shadow that looks like an underline. On hover, we can adjust the settings to change its appearance:
The web, as a platform, is open and free. Unlike native app markets, we don’t have to wait for software to be approved by any third-party. It works across any device or operating system that has a web browser. (Which is why standards across browsers is so important). But, until recently web-apps faced limitations. Not having full access to a device’s hardware and operating system was an issue – but that’s being fixed as more native APIs are being added to modern web browsers.
A disadvantage of having a web-only app was losing out on the discoverability that comes with having it listed in a searchable marketplace. Adding a web-app to your device home screen, from a web browser, is not intuitive to average users. Fortunately, the Google Play Market allows us to upload an app file that links to a progressive web app.
I had to make sure it qualified as a PWA. It needed offline support, as well as any other features that would make it feel like a native app. Google Chrome’s developer tools has a section called “Audits” that helped me identify such opportunities.
That command shows us the certificate fingerprints. Copy the SHA256 value. It is used with Google’s Statement List Generator to create the contents of the assetlinks.json file. The statement file is then placed in a “.well-known” directory on the root of our PWA domain (eg.https://www.bjjtracker.com/.well-known/assetlinks.json)
This app is a side project I use to toy with new web technologies. I’m trying to drive traffic to it so that I can experiment with optimizing conversions. I’m using it as a trial grounds for another software service called SplitWit. SplitWit is focused on optimizing conversions for the web, and helping digital marketers reach their goals. You can read about it on another post from this blog.
