Question

How to add "Require" beside the tag field in the asking question page

Answer 1

1) allow tags in "Admin > General".

2) set minimum number of tags in "Admin > Posting" in the field "Minimum number of tags:".

3) if you want to add a red text before the tag's input box, add this css code in your theme:

tr:nth-child(8) > .qa-form-tall-label::after {

    content: "* Required";
    color: red;

}

if it didn't add text to the right lable, try to decrease or increase the number inside parentheses.

I have added the line :
              tr:nth-child(8) > .qa-form-tall-label::after { content: "* Required"; color: red; }
to the end of the file :
               public_html/qa-theme/SnowFlat/qa-styles.css

then I updated the line :
    return 'qa-styles.css?' . QA_VERSION;
to
         return 'qa-styles.css?1' . QA_VERSION;
in:
           qa-theme-base.php
to force the changes , but nothing happened
