<a> inside of a <header> won't move to the bottom - css

Question

I have my code here in css for the a inside the header:
header {
display: block;
background-color: black;
color: white;
width: 100%;
height: 150px;
position: relative;
min-width:200px;
}
header img {
float: left;
}
header a {
color: white;
font-family: 'Roboto Slab', sans-serif;
font-weight: 100;
font-size: 200%;
text-decoration: none;
float: left;
}
<header>
<div class="header-image-container">
<img src="benny.jpg" alt="Benny logo">
</div>
<h1 class="site-title">Benny's List</h1>
</header>
I just want the a that is inside the header to be down towards the bottom of the header but no matter if I put margin or padding, it won't move at all. Thank you guys for any help!

Answer 1

You probably just need to add clear for your hyperlink
header {
display: block;
background-color: black;
color: white;
width: 100%;
height: 150px;
position: relative;
min-width: 200px;
}
header img {
float: left;
}
header a {
color: white;
font-family: 'Roboto Slab', sans-serif;
font-weight: 100;
font-size: 200%;
text-decoration: none;
float: left;
clear: both; /* Added */
}
<header>
<img src="https://via.placeholder.com/100x100">
Link
</header>

There is no need of using floats when u don't need them next to each other, have a look at the below working snippet without using float: left, hope it helps :)
header {
display: block;
background-color: black;
color: white;
width: 100%;
height: 150px;
position: relative;
min-width: 200px;
}
header img {
/* float: left; */ /* removed */
display: block; /* Added */
}
header a {
color: white;
font-family: 'Roboto Slab', sans-serif;
font-weight: 100;
font-size: 200%;
text-decoration: none;
/* float: left; */ /* removed */
}
<header>
<img src="http://placekitten.com/g/80/80">
Link
</header>

Answer 4

Just play with negative value of margin-top of img according to your requirement.
It will work. Below is the css code:
header img {
float: left;
margin-top: -10px;
}
Just tweak the value of margin-top according to your requirement.
