Reveal div in inline position

Question

Trying to slide reveal a div but it seems there's a jitter or div won't be inline due to the display:block or something. What I want is when I click Share button, the div with social-icon reveals smoothly beside Share button. Someone please shed some light. Thanks in advance.

Update Css Using Float:left.

$('.social').click(function(){
    $('.social-icons').toggle("slide");
});

.social {
    display: inline-block;
    height: 47px;
    color: #58585b;
    text-transform: uppercase;
    font-size: 14px;
    line-height: 47px;
    padding: 0px 20px;
    border: 1px solid rgba(88,88,91,0.5);
    transition: width .2s ease;
    float: left;
}
.social-icons {
    display: inline-block;
    height: 47px;
    color: #58585b;
    font-family: "freight-text-pro",sans-serif;
    text-transform: uppercase;
    font-size: 14px;
    line-height: 47px;
    padding: 0px 20px;
    border: 1px solid rgba(88,88,91,0.5);
    /* margin-left: -5px; */
    display: none;
    float: left;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="social">
    <a>SHARE</a>
</div>
<div class="social-icons">
    <a>FB</a>
    <a>TW</a>
    <a>G+</a>
    <a>WS</a>
</div>
