How to extend the text in announcement header across (minimal theme)

The text in my announcement header is positioned on the left had side, I want to extend the text and change it so that i runs clearly in the centre if the announcement banner. Please can someone help me with this? I have read previous posts about this and how to update the asset liquid code but it is not working for me.

Thanks,

June

@Zworthkey Please let me know if you need anymore information.

Thanks,

Can you give me a screenshot of your problem so,
I can solve it perfectly.

Yes of course. The ‘Christmas delivery, UK…’ is positioned on the left. I would like to have the text extended across the announcement banner so is centred.

Paste this code on top of the theme.css file.

.header-bar__left.post-large--display-table-cell {
    position: absolute !important;
    left: 30% !important;
    top: 9px !important;
}

Thank You.

Where can I find the theme.css file? Which section or area is that in? And when you say the top - do you mean before all of the code?

I did this and nothing changed. Please find attached the screenshot.
