.parent
{
    width: 100%;    
    border: 1px solid blue;

    border: 1px solid red;
    margin: 2px;

<div class="parent">

Answer 1

尝试使用display: inline-block和text-align: center

.parent {
    width: 100%;
    border: 1px solid blue;
    text-align: center;
}

.child {
    display: inline-block;  
    border: 1px solid red;
    margin: 2px;
}

Answer 2

柔性溶液：设置justify-content: center;到父元素：

.parent {
  display: flex;
  justify-content: center;
  /* align-items: center; /* To align vertically, if needed */
}

.parent, .child { border: 1px solid #000; }

<div class="parent">
    <div class="child">child1</div>
    <div class="child">child2 - center us child divs! :)</div>
    <div class="child">child3</div>
</div>
