I have a particular setup that allows 4 images set side by side and to act responsively in a list format.
I am trying to have a caption with a background matching the same height as the text and extending to the width of the image, to be centered vertically and horizontally when hovered.
I have read numerous articles where position absolute/relative is used, but I can't get it working in my code. I tried vertical align, text-center, top, left, width, but the text still remains at the bottom of the image.
Here is about 10% of the links I have clicked on:
- Horizontal centering text over image via CSS
- Responsive image with text overlay
- Centering things
- Text over image without absolute position
- How to put text over an image without absolute positioning or setting the image as backbround
- Why can't an <ul> (with absolute position) inside a <li> (with relative position) auto size?
- HTML: center image caption relative to image?
I am sorry for the long post (Its's all the code so just skip the code to the jsfiddle).
My currrent setup Here is a link to the jsFiddle:
HTML:
<ul class="tab">
<li>
<a class="tabimg gq-module-hover tilt" tabindex="0" data-about="Newborns"><img src="http://debora.com.au/wp-content/uploads/2016/11/DEB_0095.jpg" alt="">Newborns</a>
</li>
<li>
<a class="tabimg gq-module-hover" tabindex="1" data-about="Children"><img src="http://debora.com.au/wp-content/uploads/2016/11/DEB_8252.jpg" alt="">Children</a>
</li>
<li>
<a class="tabimg gq-module-hover" tabindex="2" data-about="Families"><img src="http://debora.com.au/wp-content/uploads/2016/11/DEB_8607.jpg" alt="">Families</a>
</li>
<li>
<a class="tabimg gq-module-hover" tabindex="3" data-about="Lifestyle"><img src="http://debora.com.au/wp-content/uploads/2016/11/DEB_6620.jpg" alt="">Lifestyle</a>
</li>
</ul>
CSS:
/* Style the list */
ul.tab {
whitespace: nowrap;
width: 100%;
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
text-align: center;
}
/* Style the a tags */
ul.tab li a {
display: inline-block;
color: black;
text-align: center;
text-decoration: none;
transition: 0.3s;
font-size: 17px;
-webkit-filter: grayscale(50%); /* Safari 6.0 - 9.0 */
filter: grayscale(50%);
}
/* Change background color of links on hover */
ul.tab li a:hover {
background-color: #000000;
-webkit-transform: scale(1.1, 1.1);

box-shadow: 1px 5px 14px rgba(0, 0, 0, 3);
z-index: 1;
-webkit-filter: grayscale(0%); /* Safari 6.0 - 9.0 */

}
/* Create an active/current tablink class */
ul.tab li a:focus, .active {
background-color: #ccc;
-webkit-filter: grayscale(0%); /* Safari 6.0 - 9.0 */
filter: grayscale(0%);
}
/* Style the tab content */
.tabcontent {
display: none;
padding: 6px 12px;
border: 1px solid #ccc;
border-top: none;
}
/*style the images*/
.tabimg {
box-sizing: border-box;
}
.tab {
font-size: 0; /* To get rid of the space below the li tags */
display: inline-block;
/* change this to display: block; in order to make the container as wide as the page is */
box-sizing: border-box;
overflow: hidden;
/* to clear the float */
}
.tab li {
box-sizing: border-box;
float: left;
width: 25%;
}
.tab li a {
width: 100%; /* remove this if you dont want the images to resize if the container is as wide as the page (if .tab is display: block;*) */
}
.tab li img {
width: 100%;
display: block;
box-sizing: border-box;
}
Javascript
/* Simple foreach as the js foreach method is not supported by IE9 and you may want to support it.

function simpleForEach(array, callback) {
for (var i = 0; i < array.length; i++) {
callback(array[i], i);
}
}
/* Parts of this can be done with pure css.
This function should executed on load:
document.addEventListener("load", load);
or on DOMContentLoaded:
document.addEventListener("DOMContentLoaded", load);

jQuery(document).ready(function(){
var tabimgs = document.getElementsByClassName("tabimg");
// for each tabimg
simpleForEach(tabimgs, function(tabimg) {
var cityName = tabimg.getAttribute("data-about");
// add the click event listener
tabimg.addEventListener("click", function(evt) {
// onclick do:
// hide all tabcontents
simpleForEach(document.getElementsByClassName("tabcontent"), function(tc) {
tc.style.display = "none";
});
// remove the active class
simpleForEach(document.getElementsByClassName("tabimg"), function(ti) {
ti.className = ti.className.replace(" active", "");
});
// show the current tab, and add "active" class to the link that opened the tab
document.getElementById(cityName);
tabimg.className += " active";
});
});
});
I would really appreciate some help/guidance on this one please. Thank you in advance.
