Limitations & Rules

1. If you want to write newline character, you can use these tags \<br>, \<div> or use "\n".
   • "attributed \<br> string"
   • "attributed \<div> string\</div>"
   • "attributed \n string"

2. You can use following html tags
   • br → newline
   • div → newline and general tag for styling
   • span → general tag for styling
   • font → has attribute as color(color), size(font-size) and face(font-family)
   • b → bold style
   • u → underline style
   • i → italic style
   • a → has attribute href for link.
   • s → line-through
   • strike → line-through

3. You can only use following css styles
   • font.family-style → font-family → "font-family: Nunito-ExtraBold;"
   • font.italic → font-style → "font-style: italic;"
   • font.size → font-size → "font-size: 24px;" (24pt, 24dp)
   • font.bold → font-weight → "font-weight: bold;"
   • foregroundColor → color → "color: rgb(127, 125, 127);"
   • backgroundColor → background-color → "background-color: rgb(255, 125, 127);"
   • underline → text-decoration-line → "text-decoration-line: underline;"
   • strikethrough → text-decoration-line → "text-decoration-line: line-through;"
   • link → href → "click <a href=\"https://smartface.io\"> here </a> "
   • ios.underlineColor → text-decoration-color → "text-decoration-color: rgba(255, 125, 128);"
   • ios.strikethroughColor → text-decoration-color → "text-decoration-color: rgba(24, 126, 168);"

4. ⚠️ If you give font-family style, this style can overwrite font-weight and font-style.
   • font-family: Nunito-ExtraLightItalic; → this overwrite font-weight as normal.
