I am a beginner attempting to merge HTML and CSS because the platform I'm using (getresponse) doesn't allow the uploading of separate .css files. It seems like I must be doing something incorrectly, but here is the HTML code:
#cont {
display: none;
}
.show:focus+.hide+#cont {
display: block;
}
<div>
<a href="#show" class="show">[Show]</a>
<a href="#hide" class="hide"></a>
<div id="cont">Content</div>
</div>
How can I achieve this? I tried writing the .css first without success.
