    var attributedStrings = createAttributedStrings(htmlSource);
    textView.attributedText = attributedStrings.map(s => new AttributedString(propFactory(s)));
```

## 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.
