change color of navigation bar & the heading below it.

You can add this to your child style.css:

.entry-header .entry-title {
    color: #00FF00; // this will change the title under the nav bar to green
}

.main-navigation ul.nav-menu, .main-navigation div.nav-menu > ul {
    background-color: #00FF00; // this will change the nav bar to green
}

i dont have a child theme. I just tried to make one and it says my stylesheet is missing. I cant figure out why. I’m using Filezilla
https://www.databasedog.com/wordpress/

looks like this:
/*
Theme Name: Twenty Twelve Child
Theme URI:

child/
Description: Twenty Twelve Child Theme
Author: fabfrankie
Author URI: https://databasedog.com/wordpress
Template: twentytwelve
Version: 1.0.0
Tags: light, dark, two-columns, right-

sidebar, responsive-layout, accessibility-ready
Text Domain: twenty-twelve-child

@import url(“../twentytwelve/style.css”);

/* =Theme customization starts here

This stylesheet uses rem values with a pixel

fallback. The rem
values (and line heights) are calculated using two

variables:

$rembase: 14;
$line-height: 24;

———- Examples

* Use a pixel value with a rem fallback for font-

size, padding, margins, etc.
padding: 5px 0;
padding: 0.357142857rem 0; (5 / $rembase)

* Set a font-size and then set a line-height based

on the font-size
font-size: 16px
font-size: 1.142857143rem; (16 / $rembase)
line-height: 1.5; ($line-height / 16)

I found this posted by a good samaritan:
“If you used Notepad it is possible it added .txt to the end of your file … try this…rename it to style.css and you’ll be fine”
when i went to rename it was in fact .txt. Child theme here I come!
Now I will try your CSS kaniamea…

Dear Kaniamea, It didnt work.
Maybe I put it in the wrong place?

/* Clearing floats */
.clear:after,
.wrapper:after,
.format-status .entry-header .entry-title {
color: #00FF00;
}

.main-navigation ul.nav-menu, .main-navigation div.nav-menu > ul {
background-color: #00FF00; //
}:after {
clear: both;
}
.clear:before,
.clear:after,
.wrapper:before,
.wrapper:after,
.format-status .entry-header:before,
.format-status .entry-header:after {
display: table;
content: “”;
}

Hi Frankie,
I don’t see the code I put above in your child theme. Please make sure you include it in your child style.css.

Hi Kaniamea,
it is in there, I just got rid of the part that says // this will change the title under the nav bar to green
the addition: color #00F00 wasnt in the original css.
Thanks,
frankie
