Upgrade Ionic Version from 4 to 5 #12
Description
It would be great to update the packages using an older version to the newer version. Also, we should take care of breaking changes. At the moment, the only problem that we have is using html attributes instead of css classes.
In resume, we should do the following:
- update the ionic packages to the latest usable version.
- change the html attributes used for styling to its css class type.
