Make a parent container that will contain all the images you want in a row and use flex properties.

e.g:

.row-one,  .row-two{
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
}

<div class="row-one">
  <span>Image 1</span>
  <span>Image 2</span>
  <span>Image 3</span>
</div>

<br>
<br>

<div class="row-two">
  <span>Image 4</span>
  <span>Image 5</span>
  <span>Image 6</span>
</div>

Try Grids; it is much better to display galleries.

But in this scenario with flex elements, I would use the following approach:

.flex-div{
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
}

.flex-div > .image{
    width: 30%;
    display: flex;
    align-items: center;
    flex-direction: column;
    justify-content: space-around;
    background-color: magenta;
}

<div class="flex-div">
    <div class="image">
        <img src="custom image" alt="custom image" loading="lazy">
        <p>Some text</p>
    </div>
    <div class="image">
        <img src="custom image" alt="custom image" loading="lazy">
        <p>Some text</p>
    </div>
    <div class="image">
        <img src="custom image" alt="custom image" loading="lazy">
        <p>Some text</p>
    </div>
</div>

My flex row won’t work and I don’t know why. I’ve tried everything. I need the images to be three in a row then break and start a new row. How can I overcome this issue?

            .flex-div > div {
                display: flex;
                flex-direction: row;
                flex-wrap: wrap;
                align-content: space-between;
                
            }

            
            /*kitchen hacks*/
            #kitchen-hacks {
                padding-top: 80px;
            }
        
            .row-one {
                width: 100%;
                
            }
        
            #kitchen-hacks h2 {
                text-align: center;
                margin-bottom: 15px;
                border: solid black;
                border-radius: 10px;
                
            }
        
            #kitchen-hacks p {
                height: auto;
                width: 54%;
                margin-top: 5px;
                margin-bottom: 50px;
                border: solid black;
            }
