 * Hi all,
    I created a child theme and the following errors are shown when I use
   DeveTool for Chrome and Mozilla:
 * **1-Chrome**:
 * _[Violation] Forced reflow while executing JavaScript took 55ms_
    And not allways
   appear this error: _[Violation] ‘setTimeout’ handler took 390ms masonry.pkgd.
   js?ver=20151215:691_
 * **Cuestions**: Why does these errors are shown? How can I resolve them?
 * **2-Mozilla:**
 * _URL del recurso: [http://localhost/Cover/wp-content/themes/MusicTheme/css/bootstrap.min.css?ver=4.9.4](http://localhost/Cover/wp-content/themes/MusicTheme/css/bootstrap.min.css?ver=4.9.4)
   
   URL del mapa fuente: bootstrap.min.css.map
 * **Cuestions**:
    Why does thess errors appear with Mozilla and not in Chrome? 
   Why are there error in Chrome and not Mozilla? How can I resolve them?
 * Thanks

 * These aren’t errors but warnings. And they are not related to WordPress…
