How can I automatically make an Image in my navbar the max height without changing the size of the n

Time：12-07

I have a navbar at the top of my page with an image logo and some hyperlinks. I want to make it so the image is always the max height it can be while staying within the foot print of the navbar. Here's what I mean:

enter image description here

As you can see, the image in the top left has 10px padding, but the image is slightly too small and has a larger gap at the bottom.

This is my code:

HTML:

<!DOCTYPE html>
<html lang="en-GB">

<head>
    <meta charset="UTF-8">
    <title>Home | Aeron</title>
    <link rel="icon" type="image/x-icon" href="./images/favicon.png">

            </ul>
        </div>
</body>

</html>

CSS:

html {
    box-sizing: border-box;
    scroll-behavior: smooth;
    font-family: 'Poppins', sans-serif;
    height: 100%;
}

body {
    margin: 0;
    background: linear-gradient(45deg, #280036 0%, #000836 100%);
    background-size: cover;
    background-repeat: no-repeat;
    background-attachment: fixed;
    height: 100%;
}


.header-logo {
    margin: 10px;
    float: left;
    height: 72px;
}

.header {
    background-color: #000000;
    overflow: hidden;
    width: 100%;
}

.desktop-nav-links {
    float: right;
    margin-right: 1.5vw;
}

.desktop-nav-links a {
    margin: 1.5vw;
    display: block;
    color: white;
    font-size: 1vw;
}  

.desktop-nav-links li {
    float: left;
    list-style: none;
}

How can I make it so no matter what screen size is, the image is always as big as it can be without influening the navbar height?

CodePudding user response：

/* put a style function in your image tag */

<img src="./images/logo.png" style=height:"" width:" " title="Aeron" alt="logo" >

CodePudding user response：

Basically by making it position:absolute inside the position:relative header, you can control where it begins top:0 and where it'll end bottom:0.

Update:

We will wrap the image inside a container. That container will take 100% of the height by using absolute position with top and bottom equals 0. It will have a padding of the desired 10px, where as inside of it the image will reside having a height of 100%.
