<p>You should add a wrapper to the title elements, and then set the size of the wrapper like the box of the image. Then use flexbox to vertically align titles inside the wrapper. Also, remove inline styles for width: 300px</p>

<p>I wanted to add a heading(bold) and a subheading(not bold) on all the images on a webpage when mouse hovers over it. I already have the effect where the image fades/changes color upon hovering. Following is the image: <a href="https://imgur.com/a/xLXSUkx" rel="nofollow noreferrer">https://imgur.com/a/xLXSUkx</a></p>

<p>Here's the HTML code for it:</p>

<pre><code>&lt;div class="JA-linkWrap JA-Notprojects JA-NotObjects floatleft" style="width:300px;"&gt;

        &lt;a href="https://canadacouncil.ca/initiatives/venice-biennale" 
        class="JA-projectPageLink"&gt;

          &lt;img src="images/GRID/111%20jpeg%20grid.jpg" alt="" class="JA- 
newsmediaImage"&gt;
         &lt;h2 class = "img_head"&gt; The Octa. &lt;/h2&gt;
         &lt;p class = "img_description"&gt; Arch. &lt;/p&gt;

            &lt;/a&gt;  

    &lt;/div&gt;   
</code></pre>

<p>This is the CSS for .JA-linkWrap:</p>

<pre><code>.JA-linkWrap {
   float: left;
   margin: 12px;
}
</code></pre>

<p>More CSS:</p>

<pre><code>* {
    margin: 0;
    padding: 0;
    border: 0;
}


.JA-linkWrap img:hover {
    -webkit-filter: brightness(90%);
}


.img_head{
  position: absolute;
  color: #000;
  visibility: hidden;
  opacity: 0;
  transition: opacity.2s, visibility .2s;

}

.img_description{
  position:inherit;

  color:#000;
  visibility: hidden;
  opacity: 0;
  transition: opacity.2s, visibility .2s;
}

.JA-linkWrap:hover .img_description{
  visibility: visible;
  opacity: 1;
}



.JA-linkWrap:hover .img_head{
   visibility: visible;
  opacity: 1;
}
</code></pre>

<p>Here's the outcome of my attempt when I hover the mouse over the image: <a href="https://imgur.com/a/Fkuf0eE" rel="nofollow noreferrer">https://imgur.com/a/Fkuf0eE</a> <strong><em>As you can see the heading and description of the image are both under the image. I want them to be in the center of the image.</em></strong> Please be specific, I am new to this. </p>


Make the text to be in the middle of the image when mouse hovers over the image
