Update:
I realized that the reason that HTML modification hasn’t been working is because i’ve been trying to mess with header.php when I should be in the slider.php.
I found this tag:
<h2 class="maintitle"><?php echo esc_html($slider_title_1); ?></h2>
<p class="subtitle"><?php echo esc_html($slider_subtitle_1); ?></p>
</div>
And replaced with this
<h2 class="maintitle"><?php echo esc_html($slider_title_1); ?><img src="https://idtrythat.com/wp-content/uploads/2015/08/ID-Try-that-3-011.png" alt="things to do in rexburg" border="0" /></h2>
<p class="subtitle"><?php echo esc_html($slider_subtitle_1); ?></p>
I then went into the CSS and added this line:
.maintitle {
height: auto;
width: auto;
max-width: 300px;
max-height: 300px;
}
However after doing this, it cut off the button part of the image, and the call to action button is gone. Where did I go wrong?
