Styling a fixed sidebar in Vue.js

I am currently working on a layout design that includes a fixed sidebar on the left side, positioned beside a container with its own grid structure. Utilizing Vue.js means each template contains <div> elements where I attempt to incorporate additional <div>s for the sidebar and main content. Unfortunately, my layout seems to be rejecting CSS rules when trying to style the sidebar or apply colors. Any assistance would be greatly appreciated!

Here is how my layout is structured:

<template>
 <div>
  <sidebar />
  <main-content />
 </div>
</template>

The sidebar component looks like this:

<template>
<div>
<div class="sidebar">
  <div id="logo">
    <img src="" />
  </div>
  <h1><a href="#">Company</a></h1>
  <ul>
    <li><a href="#">Users</a>
      <ul id="sublist">
        <li><a href="#">Import</a></li>
        <li><a href="#">Invitations</a></li>
      </ul>
    </li>
    <li><a href="#">Polls</a></li>
  </ul>
 </div>
</div>
</template>

The main content section, which houses a table component, is structured as follows:

<template>
<div>
<div class="container-grid">
  <div class="header">
    <h2>Users</h2>
    <button>Add</button>
    <h3>Import users</h3>
  </div>
  <main-table />
 </div>
</div>
</template>

My current CSS styles are set up like this:

.sidebar {
height: 100%;
width: 300px;
max-width: 1024px;
position: fixed;
z-index: 1;
top: 0;
left: 0;
overflow-x: hidden;
box-sizing: border-box;
}
h1 {
display: inline;
height: 29px;
width: 156px;
}
ul,
#sublist {
list-style: none;
margin: 0;
padding: 0;
}
a {
height: 20px;
width: 200px;
text-decoration: none;
display: block;
}

// Main Content Style

.container-grid {
margin-left: 336px;
}

Answer №1

Although this may not directly answer your question, I wanted to provide a helpful tip.

You don't have to include a div tag every time you use components. The key is to have only 1 root element in your structure.

If you have multiple elements like this example, then wrapping them is necessary:

<template>
    <div>
        <span></span>
        <span></span>
    </div>
</template>

However, for a single span element, you can simply leave it in the template without wrapping it:

<template>
    <span></span>
</template>

Answer №2

Everything seems to be functioning correctly in the demo, but I encountered a curious issue: the styling for .container-grid wasn't applying as expected. After some investigation, I discovered that the problem stemmed from an embedded comment (// Main content style), which is not valid CSS syntax. It's worth noting this discrepancy in case it causes any complications in your own development environment.

new Vue({
  el: "#app",
  components: {
    sidebar: {
      template: '#sidebar-template'
    },
    mainContent: {
      template: '#main-template'
    }
  }
});
.sidebar {
  background-color: #fee;
  height: 100%;
  width: 150px;
  max-width: 1024px;
  opacity: 0.5;
  position: fixed;
  z-index: 1;
  top: 0;
  left: 0;
  overflow-x: hidden;
  box-sizing: border-box;
}

h1 {
  display: inline;
  height: 29px;
  width: 156px;
}

ul,
#sublist {
  list-style: none;
  margin: 0;
  padding: 0;
}

a {
  height: 20px;
  width: 200px;
  text-decoration: none;
  display: block;
}

.container-grid {
  background-color: #eef;
  margin-left: 180px;
}
<script src="//unpkg.com/vue@latest/dist/vue.js"></script>
<div id="app">
  <sidebar></sidebar>
  <main-content></main-content>
</div>

<template id="sidebar-template">
<div>
<div class="sidebar">
  <div id="logo">
    <img src="" />
  </div>
  <h1><a href="#">Company</a></h1>
  <ul>
    <!--<li><a href="#">About</a></li>-->
    <!--<li><a href="#">Popular</a></li>-->
    <!--<li><a href="#">News</a></li>-->
    <!--<li><a href="#">Pages</a></li>-->
    <li><a href="#">Users</a>
      <ul id="sublist">
        <li><a href="#">Import</a></li>
        <li><a href="#">Invitations</a></li>
      </ul>
    </li>
    <!--<li><a href="#">Organisations</a></li>-->
    <li><a href="#">Polls</a></li>
  </ul>
 </div>
</div>
</template>

<template id="main-template">
<div class="container-grid">
  <div class="header">
    <h2>Users</h2>
    <button>Add</button>
    <h3>Import users</h3>
  </div>
 </div>
</template>

Answer №3

Here's an example of how you could structure your HTML and CSS:

<div class="container">
    <aside>
        <p>sidebar</p>
    </aside>

    <section>
        <h2>Section1</h2>
        <p>section1 whatever data you want to put in this section</p>
    </section>
    
    <section>
        <h2>Section2</h2>
        <p>section2 whatever data you want to put in this section</p>
    </section>
    
    <section>
        <h2>Section3</h2>
        <p>section3 whatever data you want to put in this section</p>
    </section>

    <section>
        <h2>Section4</h2>
        <p>section4 whatever data you want to put in this section</p>
    </section>
</div>

In the CSS, you can style the layout like this:

.container {
    display: flex;
}

aside {
    width: 20%;
}

section {
    width: 80%;
}

Make sure to adjust the height so that it covers the entire page and not just the viewport height.

This layout will position all sections to the right of the sidebar in a flexible manner.
