I did some research about ” nth-child(x) ” and i saw that if i replace “x” with the no. of the article i can replace the background color with the one i chose.
For those who need the answer to my question :
1- install : https://wordpress.org/plugins/simple-custom-css/
2- In custom CSS add this:
-this code will replace the 1 article background with red
article:nth-child(1){
background:red !important;
}
Hey Rodica,thanks for your answer,the addon is useful,but i don’t want the rectangular shapes to have the same color.I want to make separate colors for every box.
