How to Create a Child Theme in WordPress

Within the WordPress file structure there must be a folder that is called wp-content. It saves the themes that you have installed (whether or not they are activated). You have to choose the theme for which you want to create a child theme. The most normal thing will be that it is generated from the theme that at that moment is active. The theme is chosen and a new folder is created, where the files are to be entered. It should be named the following way to nametheme-child, where “nametheme” is the name of the folder of the theme for which you want to create the child theme. Enter the folder and must be generated on the one hand a file called style.css( which must be filled with information) and another called functions.php. Like style.css should be saved in the root directory of the child theme.
