 ## Provide the gradle dependency
-```
+``` groovy
 compile 'com.vivian.widgets:TimeLineItemDecoration:1.4'
 ```
 
 ## Usage
 If you want to use this *TimeLine*  in your project, you have to do the following.
 
 - Set the `StaggeredGridLayoutManager` to your `RecyclerView`
-```
+``` java
 mRecyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL));
 ```
 
 - Use the `ItemDecoration` of this project [ItemDecoration.java](https://github.com/vivian8725118/TimeLine/blob/master/app/src/main/java/com/vivian/timeline/timeline1/ItemDecoration.java)
-```
-mRecyclerView.addItemDecoration(new ItemDecoration(this,100));
+``` java
+mRecyclerView.addItemDecoration(new ItemDecoration(this, 100));
 ```
 The second ctor-parameter will define the `distance`. In that case 100px.
 
 Currently there are 2 styles available, as seen in the Screenshots. You can find the implementation for the second style here. [DotItemDecoration.java](https://github.com/vivian8725118/TimeLine/blob/master/app/src/main/java/com/vivian/timeline/itemdecoration/DotItemDecoration.java)  
-```
-  DotItemDecoration mItemDecoration = new DotItemDecoration
+``` java
+DotItemDecoration mItemDecoration = new DotItemDecoration
                 .Builder(this)
                 .setOrientation(DotItemDecoration.VERTICAL)//if you want a horizontal item decoration,remember to set horizontal orientation to your LayoutManager
                 .setItemStyle(DotItemDecoration.STYLE_DRAW)//choose to draw or use resource

 if you want to do something according to the column of span,implements `SpanIndexListener` of this project [SpanIndexListener](https://github.com/vivian8725118/TimeLine/blob/master/app/src/main/java/com/vivian/timeline/itemdecoration/SpanIndexListener.java).
