Background question

Yes it’s possible, but we need a link to your site. Looking at an image is not helpful.

I also think that some clarification is needed. Are you saying that you don’t want the white background? Instead you just want the dark lines?

If so, find out what div that is that contains the search, locate it in the css and then remove the background colour.

You want the white area to use the same pattern as the darker area behind it?

If so, you’ll need to find the image that you used for your main background and get the url for it. Then in your CSS do something like

#branding {
     background-image: url('IMAGE_URL_HERE');
}

and that will apply the same image to the white area.

You should provide us full template or website urls. You exist template is not telling full story

https://luukdc.nl is my website link. You’ll spot the ididit logo with a big black beam on top of it. That big black beam, i want it gone or transparent so it would show the background instead of the black. I

Sorry luukdc, but I still don’t know what you are taking about.

That big black beam?????????

Do you mean the margin above your header? In your style.css you’ll find

body {
    padding: 0 2em;
}

change that to padding:0;

that will remove the margin.

Your custom logo, contains the black background, if you don’t want that then just update the image.
