Question

CSS:

.share {
    width: 150px;
    height: 20px;
    background: #000;
    float: right;
    white-space: nowrap;
    padding-top: 5px;
    padding-bottom: 5px;
    padding-left: 3px;
    background-color:rgba(255, 255, 255, 0.5);
    border-bottom-left-radius: 5px;
    box-shadow: 0px 0px 10px #888;
    vertical-align: top;
}

HTML:

<div class="share">
    <div class="fb-like" data-href="http://bronies.info/" data-send="false" data-layout="button_count" data-width="450" data-show-faces="true" style="width:47px; overflow:hidden; top:-3px; left:3px;"></div>
    <a href="https://twitter.com/share" class="twitter-share-button" data-text="Wondered what the bronies were all about?" data-count="none">Tweet</a>
    <div class="g-plusone" data-size="medium" data-annotation="inline" data-width="300" style="width:32px; overflow:hidden;"></div>
</div>

Chrome, Safari:

Internet Explorer, Firefox, and Opera:

If you can see what I did in my HTML style property, I used top:-3px, and I did this before testing my website out on other browsers (Chrome is my primary web browser). I used top because a quick Google search led me a page instructing me to do so. Now that this solution doesn’t work, how would I adjust it to align and work on all web browsers?

Answer 1

You should remove top:-3px; completely. Because you don’t have position:relative;, which is required (something other than static) to activate positioning, then Webkit (Chrome, Safari) is correctly ignoring it, but Internet Explorer, Firefox, and Opera are mistakenly honoring it (-3px shift).

EDIT:

From the comments…
Facebook’s script adds a <span> inside your <div> which then triggers a CSS rule they also provide: .fb_iframe_widget span { vertical-align: text-bottom; }. I suggest adding float: left; to all three of your <div> tags so they will not share a common flow (or baseline).
