Question about "KePub stylesheet additions"

Spoiler:

KePub stylesheet additions:
- Enabled: no
- Description: Makes room to add some additional CSS to the default KePub stylesheet.
# See replacement CSS below for examples.
- FindBaseAddressString: ".KBHighlighting, .KBSearchResult {"
- ReplaceString: {Offset: 0, Find: ".KBHighlighting, .KBSearchResult { background-color: #C6C6C6 !important; } \t", Replace: ".KBHighlighting,.KBSearchResult{background-color:#C6C6C6!important}.KBSearch", MustMatchLength: yes}
- ReplaceString: {Offset: 76, Find: ".KBSearchResult, .KBAnnotation, .KBHighlighting { font-size: 100% !important; -webkit-text-combine: inherit !important; } \t", Replace: "Result,.KBAnnotation,.KBHighlighting{font-size:100%!important;-webkit-text-combine:inherit!important}.KBAnnotation[writingM", MustMatchLength: yes}
- ReplaceString: {Offset: 199, Find: ".KBAnnotation[writingMode=\"horizontal-tb\"] { border-bottom: 2px solid black !important; } \t", Replace: "ode=\"horizontal-tb\"]{border-bottom:2px solid black!important}.KBAnnotation[writingMode=\"ver", MustMatchLength: yes}
- ReplaceString: {Offset: 290, Find: ".KBAnnotation[writingMode=\"vertical-rl\"] { border-right: 2px solid black !important; } \t", Replace: "tical-rl\"]{border-right:2px solid black!important}.KBAnnotation[writingMode=\"vertical-lr", MustMatchLength: yes}
- ReplaceString: {Offset: 378, Find: ".KBAnnotation[writingMode=\"vertical-lr\"] { border-left: 2px solid black !important; }", Replace: "\"]{border-left:2px solid black!important}/******************************************/", MustMatchLength: yes}
#
# Replacement value: CSS string of exactly 44 characters in length:
#
# Example 1: Make full justification the default:
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-align:justify }", MustMatchLength: yes}
#
# Example 2: text-renderingptimizeSpeed: Disables kerning, but fixes some
# rendering problems that affect fully justified text.
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-renderingptimizeSpeed }", MustMatchLength: yes}
#
# Example 3: text-renderingptimizeLegibility: Enables ligatures, but causes
# some additional rendering problems for fully justified text.
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-renderingptimizeLegibility }", MustMatchLength: yes}
#
# Example 4: Make KePub font sizes match ePub font sizes: ePubs render with
# 1.5 times the font size of KePubs by default. With this enabled they match.
# - FindReplaceString: {Find: "/******************************************/", Replace: "#book-inner{font-size:1.5em }", MustMatchLength: yes}

If I enable this patch, what differences will there be? Does anyone have a few "before and after" screenshots?
