How to add text to header?

I can not understand in what files can I edit the layout?

The easiest solution would be to add text to your logo…

Or you can add code like this to your child themes function file.

add_action( 'storefront_header', 'custom_text_next_to_logo', 25 );
function custom_text_next_to_logo() {
    echo 'This is my custom text';
}

Then you’ll have to position it correctly with css.

ok, thanks for advice, maybe i will do this.

but i’m interesting, where i can edit layout? where is sources? tell me please )

Or you can add code like this to your child themes function file.

i added this function, but what i need write in css? what style i need to edit? i wrote

.custom_text_next_to_logo {
border-radius: 1em;
padding: 1em;
top: 15%;
position: absolute;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);
max-width:180px }

but doesn’t work

Ok if you want to target the css you are going to have to change a couple things. First the php code, change to:

add_action( 'storefront_header', 'custom_text_next_to_logo', 25 );
function custom_text_next_to_logo() {
    echo '<span class="my-logo-text">This is my custom text</span>';
}

Now you can target the css class .my-logo-text

thanks, man! )
