适当的边距填充器，用于更宽宽度的响应式网格设计

Question

我已经"working with one of the many frameworks or grid systems laying out sites on a 12-column flexible grid" and since after months of using Bootstrap I have become neither a journeyman nor an apprentice, I'm experimenting with using just grids and media queries for laying out a site. The following code is a simplification of design offered through the nice tutorial at the URL just referenced, also using hints from Rachel Andrew's inspiring https://gridbyexample.com。

.box {
    background-color: #ddd; color: #000; padding: 20px;
}
.main-head { grid-area: hd; }
.content { grid-area: ct; }
.main-nav { grid-area: nv; }
.wrapper {
    display: grid;
    grid-gap: 2px;
    grid-template-areas: 
        "nv"
        "ct";
}
@media (min-width: 600px) {
    .wrapper {
        grid-template-columns: 1fr 3fr;
        grid-template-areas: 
            "nv nv"
            "ct ct";
    }
    nav ul {
        display: flex;
        justify-content: space-between;
    }
}        
@media (min-width: 1000px) {
    .wrapper {
        grid-template-columns: 1fr 4fr 1fr;
        grid-template-areas: 
            "nv ct ct"
            "nv ct ct";
    }
    nav ul {
        flex-direction: column;
    }
}
@media (min-width: 1200px) {
    .wrapper {
        grid-template-columns: 1fr 1fr 4fr 1fr 1fr;
        grid-template-areas: 
            ". nv ct ct ."
            ". nv ct ct .";
    }
    nav ul {
        flex-direction: column;
    }
}

<div class="wrapper">
    <nav class="box main-nav">
        <ul>
            <li><a href="">Nav 1</a></li>
            <li><a href="">Nav 2</a></li>
            <li><a href="">Nav 3</a></li>
        </ul>
    </nav>
    <article class="box content">
        <h1>Main</h1>
    </article> 
</div>

上面的代码试图在 window 超过某个 (1200) 宽度时模拟插入两个边距，但是使用句点填充 grid-template-area 似乎是作弊。有没有更自然的方式来插入这些边距？

您可以像在其他任何地方一样使用 margin，不是吗？当然，如果您希望两侧的 space 恰好是 1fr，那么使用带有 .

的空单元格方法是有意义的

.box {
    background-color: #ddd; color: #000; padding: 20px;
}
.main-head { grid-area: hd; }
.content { grid-area: ct; }
.main-nav { grid-area: nv; }
.wrapper {
    display: grid;
    grid-gap: 2px;
    grid-template-areas: 
        "nv"
        "ct";
    transition: margin 0.5s ease-in-out;
}
@media (min-width: 600px) {
    .wrapper {
        grid-template-columns: 1fr 3fr;
        grid-template-areas: 
            "nv nv"
            "ct ct";
    }
    nav ul {
        display: flex;
        justify-content: space-between;
    }
}        
@media (min-width: 1000px) {
    .wrapper {
        grid-template-columns: 1fr 4fr 1fr;
        grid-template-areas: 
            "nv ct ct"
            "nv ct ct";
    }
    nav ul {
        flex-direction: column;
    }
}
@media (min-width: 1200px) {
    .wrapper {
        grid-template-columns: 1fr 4fr 1fr;
        grid-template-areas: 
            "nv ct ct"
            "nv ct ct";
        margin: 0 5%;
    }
    nav ul {
        flex-direction: column;
    }
}

<div class="wrapper">
    <nav class="box main-nav">
        <ul>
            <li><a href="">Nav 1</a></li>
            <li><a href="">Nav 2</a></li>
            <li><a href="">Nav 3</a></li>
        </ul>
    </nav>
    <article class="box content">
        <h1>Main</h1>
    </article> 
</div>
