你可以在下面做。

.ProjectsParentDiv {
    // position: relative;
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    width: max-width;
    height: 40%;
    border: 1px solid black;
}

.childDiv {
    align-items: center;
    display: flex;;
    justify-content: space-around;
    background-color: lightblue;
    width: 75%;
    height: 150px;
    margin: 5px auto;
}

.childInnerDiv {
    display: flex;
    height: 95%;
}

.childInnerDiv.left {
    width: 25%; 
    background-color: green;
    border: 1px solid yellow;
}

.childInnerDiv.right {
    width: 65%;
    background-color: red;
    border: 1px solid silver;
}

<div class="ProjectsParentDiv">
    <div class="childDiv">
        <div class="childInnerDiv left">

        </div>
        <div class="childInnerDiv right">

        </div>
    </div>
    <div class="childDiv">
        Bar
    </div>
    <div class="childDiv">
        Baz
    </div>
</div>
