Question

我有两个水平条，我正在尝试对齐。它们都需要拉伸视口的整个宽度，并且其中的文本需要居中对齐。为此，我使用以下HTML：

<div class="logo-header-desktop">Header</div>
<ul class="logos">
  <li>Thing 1</li>
  <li>Thing 2</li>
</ul>
<div class="logo-footer-desktop">
  <span class="call-button">Footer</span>
</div>

以下SCSS：

.logo-header-desktop, .logo-footer-desktop {
    @media screen and (min-width: 1000px) {
        position: relative !important;
        left: -16%;
        width: 100vw;
    }
    @media screen and (max-width: 999px) {
        border: solid 2px #f2f2f2;
    }
    padding: 30px;
    text-align: center;
    font-family: 'Sedgwick Ave', cursive;
    font-size: 2rem;
}

.logo-header-desktop {
    margin-top: 5rem;
    @media screen and (min-width: 1000px) {
        background: #202020;
    }
    @media screen and (max-width: 999px) {
        border-bottom: 0;
    }
}

.logo-footer-desktop {
    padding-top: 0;
    @media screen and (max-width: 999px) {
        border-top: 0;
    }
    .call-button {
        display: block;
        font-family: 'Nunito', sans-serif !important;
        background: rgba(20, 20, 20, 1);
        padding: 20px;
        @media screen and (min-width: 1000px) {
            width: 100vw;
        }
        @media screen and (max-width: 999px) {
            box-shadow: 0 8px 6px -6px black;
        }
        transition: color 0.2s, background-color ease-in-out 0.2s;
        transform: perspective(1px) translateZ(0);
        &:hover, &:focus, &:active {
            background: #4b3be7;
            color: white;
        }
    }
}

页眉和页脚使用几乎相同的CSS。但是，这会导致页脚文本与宽度超过1000px的视口中的标题文本不对齐。 1000px以下的视口不受影响。

此行为在JSFiddle中可重现：https://jsfiddle.net/j6j4cck2/

为什么会发生这种情况，我该如何解决？

Answer 1

call-button的填充导致错位。

由于您在更宽的屏幕上给它宽度，您还需要添加box-sizing: border-box;，以便填充包含在设置的宽度中（或使用CSS Calc width: calc(100vw - 40px);）

.call-button {
    display: block;
    font-family: 'Nunito', sans-serif !important;
    background: rgba(20, 20, 20, 1);
    padding: 20px;
    box-sizing: border-box;                        /*  added property  */
    @media screen and (min-width: 1000px) {
        width: 100vw;
    }

            height: 7vmin;
        }
    }
  }

Answer 2

您需要从这些元素中删除left属性。您的负值为-16%。见this updated fiddle。从代码中删除下面注释的代码。

.logo-header-desktop, .logo-footer-desktop {
  @media screen and (min-width: 1000px) {
    position: relative !important;
    left: -16%; /* Delete this. Line 21 */
    width: 100vw;
  }
}

将其从以下位置删除：

ul.logos {
  @media screen and (min-width: 1000px) {
    background: #202020;
    position: relative;
    left: -16%; /* Delete this. Line 72 */
    width: 100vw;
  }
}

然后，您需要将box-sizing: border-box添加到某些元素，并将.call-button更改为100％，因为100vh在带填充或边距的div中不起作用。

ul.logos,
.logo-footer-desktop,
.call-button {
  box-sizing: border-box; /* Add this. */
}
.call-button {
  width: 100%; /* Change from 100vh to 100%. Line 48. */
}
