Hey, i added a header widget. It seems how I want, but a link dosent work, I dont understand why. I added this code on widget (text-7)

<a href="https://domain.de/blog/"><img class="bloglogo" src="https://domain.de/wp-content/uploads/2015/10/blog-logo.png" alt="blog-logo" width="170" height="70" /></a>

<a href="https://domain.de/blog/"><img class="bloglogo2" src="https://domain.de/wp-content/uploads/2015/10/blog-logo.png" alt="9001_ger_tc_p" width="85" height="35" /></a>

#header #text-7 {
    left: 131.4%;
}

.header-scrolled#header #text-7 {
    left: 110.5%;
    width: 50%;
}

.header-scrolled .bloglogo2, .bloglogo { display: block; }
.header-scrolled .bloglogo, .bloglogo2 { display: none; }
