nth-of-type selector not working as expected

Question

I only want to select the first h2 and first p from #section_5, thus I used this CSS:

#section_5 div:nth-of-type(1) h2{
    color:green;
}
#section_5 div:nth-of-type(1) p{
    color:blue;
}

But it selects all other children divs of #section_5 which doesn't seem to satisfy the selector: nth-of-type(1)

/*style the more features title*/
#section_5 div:nth-of-type(1) h2{
    color:green;
}

/*style the more features paragraph*/
#section_5 div:nth-of-type(1) p{
    color:blue;
}

<div id="section_5">                    
    <div class="row just_space1 title">
        <div class="col-12 text-center">

Could you shed the light on this, or am I doing this wrong?

Answer 1

You need to consider the > selector to avoid selecting nested elements. Your selector will select all the div that are nth-of-type(1) at any level not only the div that are child of #section5.

/*style the more features title*/
#section_5 > div:nth-of-type(1) h2 {
  color: green;
}


/*style the more features paragraph*/
#section_5 > div:nth-of-type(1) p {
  color: blue;
}

<div id="section_5">
  <div class="row just_space1 title">
    <div class="col-12 text-center">
