SKINNING IS NOT CSSINGWe all have been there!

SKINNING IS NOT CSSINGProblems you face when working with ADF Skinning as a CSS file:

Component generated HTML doesn't match the front-end visionDifferent syntax of CSSCan't use browser's prefixed values

CSS Version .my-style{ background-image: -moz-linear-gradient(left, red, #f06d06); background-image: -webkit-gradient(linear, left top, right top, from(red), to(#f06d06 background-image: -o-linear-gradient(left, red, #f06d06); background-image: linear-gradient(to right, red, #f06d06);}

ADF End Result .ps20{ background-image: linear-gradient(to right, red, #f06d06);}

SKINNING IS NOT CSSINGWhy Front-end developers can't create ADF compatible skin

They need to use JDeveloper and Create ADF application towork withADF Skinning style can be intimidatingCan't work offlineAdapted CSS may require changing the ADF page componentsstructure

SKINNING IS NOT CSSINGStill there are difficulties for ADF Developers to do skinning

CSS can be intimidatingCSS is not DRY enoughHarder to maintain

MAKE SKINNING SASSYSASS (Syntactically Awesome Style Sheets) is an Extension of

CSS

Makes very DRY CodeCan reuse variablesCan create nested stylesCan create mixin (methods) and inheritanceCan use operatorsCan use LoopsCan use ConditionsCan use lists and maps (newest version of SASS)Works well with ADF skin css syntaxMature with great community supportGenerates well formatted CSS

MAKE SKINNING SASSYVariables example

$font-stack: Helvetica, sans-serif;$primary-color: darken(#666, 50%);

.AFDefaultFontFamily:alias { font: 100% $font-stack;}.AFTextColor:alias{ color: $primary-color;}

MAKE SKINNING SASSYNesting example

af|column{

background-color: $background-color;

&::data-cell{

border: 0;

&:selected{ border: 1px solid $selected-color; } }}

MAKE SKINNING SASSYMixins example

@mixin colors($text, $background, $border) { color: $text; background-color: $background; border-color: $border;}

af|button.cancel-button{ @include colors(#fff, #c9302c, #ac2925);}

MAKE SKINNING SASSYInheritance example

.reset-border { border:0;}

af|messages{ @extend .reset-border ; border: 1px solid #ccc;}

af|table{ @extend .reset-border ; background: #cecece;}

MAKE SKINNING SASSYOperators example

$page-width: 960px;

.main-content{ width: $page-width / 100 * 65; //width: 624px;}.sidebar{ width: $page-width / 100 * 35; //width: 336px;}

MAKE SKINNING SASSYLoop example

@for $i from 1 through 4{ af|button.style-#{$i} { width: 60px + ($i * 10); }}

GUIDE YOUR SASS WITH A COMPASSCompass: A SASS framework that includes web's best reusable

patterns

Border radius

OpacityBox shadowText Shadowand more...

GUIDE YOUR SASS WITH A COMPASSBorder box example

@import "compass/css3"; @import "compass/utilities";

af|button{ @include border-radius(25px); /* This will generate: -moz-border-radius: 25px; -webkit-border-radius: 25px; border-radius: 25px; */}

GUIDE YOUR SASS WITH A COMPASSOpacity example

@import "compass/css3";

af|panelTabbed{ @include transparent; /* This will generate: filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0); opacity: 0; */}

af|button:disabled{ @include opacity(0.2); /* This will generate: filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=20); opacity: 0.2; */}

GUIDE YOUR SASS WITH A COMPASSText shadow example

$default-text-shadow-color: rgba(red, 0.6);$default-text-shadow-blur: 3px;$default-text-shadow-v-offset: 1px;

.main-title{ @include single-text-shadow;; /* This will generate: text-shadow: 0px 1px 3px rgba(255, 0, 0, 0.6); */}
