When you hover over an image, its opacity will change and text will overlay

Question

When you hover over an image, its opacity will change and text will overlay

I am looking for a way to decrease the opacity and overlay text on a thumbnail image when it is hovered over. I have considered a few methods, but I am concerned that they may not be efficient or elegant.

Creating a duplicated image in Photoshop with the text overlay and reduced opacity, then swapping out the original with the duplicate upon mouseover.
Using CSS to lower the opacity on hover, along with Javascript to toggle the visibility of a div containing the overlay text.

The issue I see with option 1 is that it seems like a waste of space and bandwidth, potentially leading to slow loading times. As for option 2, it seems like I would need to hard-code the location of each div, making maintenance and updates difficult. Although this may be a general question, I am struggling to find a solution. How can I achieve this simple task in a way that allows for easy addition of new thumbnails?

Answer №1

To create a visually appealing image effect, enclose your image in a <div class="thumb">
Apply position: relative to the .thumb class.
Insert a <div class="text> element within the .thumb container.

Add

display: none; position: absolute; bottom: 0

styling to the .text class.

To reveal the text on hover, use the CSS rule
```
.thumb:hover .text { display: block }
```
.

See an illustration here: http://jsfiddle.net/dYxYs/

You can further enhance this feature with JavaScript or jQuery: http://jsfiddle.net/dYxYs/1/

$('.text').hide().removeClass('text').addClass('text-js');

$('.thumb').hover(function(){
    $(this).find('.text-js').fadeToggle();
});

This approach ensures that the basic functionality remains intact even without JavaScript, while users with JavaScript enabled can enjoy the smooth fade-in effect.

Choose option 2 for an easier way to avoid writing a jQuery function for each image. Check out my demonstration on jsfiddle.

http://jsfiddle.net/daybreaker/dfJHZ/

HTML

<img src="http://placekitten.com/300/300" />
<span class="text" style="display:none">THIS IS A KITTEN</span>
<br><br>
<img src="http://placekitten.com/200/200" />
<span class="text" style="display:none">THIS IS A KITTEN</span>

jQuery

$('img').mouseover(function(){
    $(this).css('opacity','.2');
    $(this).next('span.text').show();
}).mouseout(function(){
    $(this).css('opacity','1');
    $(this).next('span.text').hide(); 
});

You may need to adjust the CSS for span.text to position it over the image, but it shouldn't be difficult.

Enclose it within an element and implement the following approach:

var tooltip;
$('div.imgwrap img').hover(function(){
   tooltip = $('<div />').text($(this).attr('title')).appendTo($(this).parent()); 
    $(this).fadeTo('fast',0.5);
},function(){
     $(this).fadeTo('fast',1);
    $(tooltip).remove();
});

using a structure like this:

<div class="imgwrap">
    <img src="http://www.gravatar.com/avatar/3d561d41394ff0d5d0715b2695c3dcf0?s=128&d=identicon&r=PG" title="text" />
</div>

For illustration purposes, here is a sample showcasing how you can adjust the text positioning to your liking using the following basic principle:

http://jsfiddle.net/Xrvha/

#container { position: relative; }

#container img, #container div {
    position: absolute;
    width: 128px;
    height: 128px;
}

#container img { z-index -1; }
#container div { 
    z-index 1; 
    line-height: 128px;
    opacity: 0;
    text-align: center;
}
  
#container:hover img {
    opacity: 0.35;
}
#container:hover div {

If you're looking to keep your HTML structure intact while adding a special effect, I recommend trying this method. Below is the jQuery code snippet:

$(function() {
    $(".thumb").mouseenter(function() {
        var $t = $(this);
        var $d = $("<div>");
        $d.addClass("desc").text($t.attr("alt")).css({
            width: $t.width(),
            height: $t.height() - 20,
            top: $t.position().top
        });
        $t.after($d).fadeTo("fast", 0.3);
        $d.mouseleave(function() {
            $(this).fadeOut("fast", 0, function() {
                $(this).remove();
            }).siblings("img.thumb").fadeTo("fast", 1.0);
        });
    });
});

Using the number 2 as a solution has proven to be quite effective in my experience. It may not be as difficult as one might initially assume.

To achieve the desired effect, simply reduce the opacity using CSS, then position a div relative to the image and overlap it. This can all be accomplished with straightforward CSS techniques. The key lies in utilizing the z-index property. Additionally, the div can easily be displayed using $('#div').slideUp().
