Allo

Black and white pictures have a satisfying charm that colour pictures do not. I wonder what colour this button really is. Since it was designed before the advent of colour TV I guess we'll never know.

Allo large left-aligned anchor

Change what the button says:

HTML

<div class="html_button btn-left">
    <a href="#" class="btn allo large">Your button text here</a>
</div>

CSS

.allo {
    background:gainsboro;
    padding:1em 1.6em;
    border-1px solid gray;
    border-radius:1px;
    color:black;
    transition:0.3s;
    opacity:1;
}
.allo:hover {
    background:gray;
    transition:0.3s;
}
