Ok, there are a couple of tweaks you’ll have to undergo, but bear with me here.
Scratch what I said before. First, go to the header img:
<img padding-left: 20px; width="1000" height="70" src="https://www.projectjonna.hu.nl/wp-content/uploads/2013/06/adcam-logo-zonder-dienstverlening-header-lichtbruin-240513.jpg" alt="Logo Adcam-Administratie" alt="Logo Adcam-Administratie">
CHANGE that to:
<img src="https://www.projectjonna.hu.nl/wp-content/uploads/2013/06/adcam-logo-zonder-dienstverlening-header-lichtbruin-240513.jpg" alt="Logo Adcam-Administration" id="logo-img">
MODIFY THAT <IMG> TAG FOR EACH PAGE
And then in your style.css code, add:
#logo-img {
margin-left: -2px;
width: 1002px;
height: 70px;
}
Next, go to line 346 in the style.css file. For the #page rule, modify it to:
#page {
background: #fff;
border: 1px solid #063d85;
border-top: 0;
}
Finally, go to line 133 of style.css. Modify the .page-template-showcase-php #content, .left-sidebar.page-template-showcase-php #content
rule to:
.page-template-showcase-php #content, .left-sidebar.page-template-showcase-php #content {
margin: 0 7.5% 0 7.6%;
width: auto;
}
Let us know how that works!
