**Motivation**
We want to build an interface that supports editors as much as possible in making high quality edits. One part of this is encouraging users to fill yet empty fields, and to enforce character limits in the UI.
**Workflow**
**Given** I am in edit mode of the termbox
**When** I see an entry field that does not contain any input
**Then** the entry field tells me what to put in there.
**Acceptance Criteria**
[] If there is no contents to a field yet, placeholder texts are shown
[] Label field: `enter a label`
[] Description field: `enter a description`
[] Alias field: ` enter an alias | separate aliases by using a "|" ` (temporary solution)
[] Hide placeholders once one or more characters are typed
[] When users enter an entry field, it is marked as active
[] The 1px underline turns blue ( #3366cc )
[] The cursor indicates the input is being accepted
