Menu Image size not Changing via css - html

Question

I have this menu bar, which is replaced by Images.
All looks good on normal view, but when I swtich to mobile view
It looks so clumsy. I tried Padding, But the individual cell do not
make up space with each other.
Here is the screenshot
li.topmenu1 {
height: 20px;
}
<nav id="category" class="drawer_block pc">
<ul class="category-nav">
<li class="topmenu1">
<img src="http://azlily.bex.jp/eccube_1/html/template/default/img/menu/home.png">
</li>
<li class="topmenu2">
<img src="/eccube_1/html/template/default/img/menu/products.png">
</li>
<li class="topmenu3">
<img src="/eccube_1/html/template/default/img/menu/about.png">
</li>
<li class="topmenu4">
<img src="/eccube_1/html/template/default/img/menu/howtouse.png">
</li>
<li class="topmenu5">
<img src="/eccube_1/html/template/default/img/menu/column.png">
</li>
<li class="topmenu8">
<img src="/eccube_1/html/template/default/img/menu/FAQ.png">
</li>
</ul>
</nav>
Note - I also tried to include FULL URL of the image
but somehow its not showing up on snippets :/

Answer 1

check this https://jsfiddle.net/1dvy2854/4/
.category-nav li {
display: inline-block;
}
#media only screen and (max-width: 600px) {
.category-nav li {
display: block;
}
.category-nav li img {
max-width: 65px;
display: inline-block;
}}

Make sure that the elements inside category-nav have correct margins and paddings.
If you want to make sure that the individual pictures for the menu look okay, you might want to set styles for the images one by one.
So, in your case you can edit the heights for all of your topmenu1, topmenu2...
Also, you can the inspect tool on Chrome to find what is causing problems like this in your CSS code. You can change the code live and see what change is causing what.
