Question

So I have this problem, which has never happened to me before.
I am trying to put a text field exactly next to an a button, which I already did and it looks great.

The problem is that it looks great on firefox, but on chrome the only issue is the button’s height. I dont know why its not taking the specified height. Everything else on my site works great (height wise) its all the same specified hight on all cross-platforms

Here is the code:

HTML

<div> <!-- filter item start -->
<p>
<a href="#" id="add-friend-feed-link">
Add Friend
</a>
</p>

<form method="post" action="" name="searchFriendForm" id="add-friend-search">
<input type="text"/ name="searchFriendText">
<input type="button" class="small green button" id="add-friend-button"/>

</form>

<hr>
</div> <!-- filter item end -->

and CSS

/* Absolutes start */

#add-friend-search{    
    display: block;
    position: absolute;
}

#add-friend-search input[type="text"]{

    -moz-border-radius:4px 0px 0px 4px;
    -moz-box-shadow:0 1px 0 #444444;
    -webkit-border-radius:4px 0px 0px 4px;
    -webkit-box-shadow:0 1px 0 #444444;
    border-radius:4px 0px 0px 4px;
    box-shadow:0 1px 0 #444444;
    background:none repeat scroll 0 0 #D4D8DF;
    border:1px solid black;
    color:#444444;
    font:13px Arial,sans-serif;
    height:19px;
    margin: 20px 4px 4px;
    padding:5px 6px 4px;
    width:250px;
    text-align: center;
    float: left;
    display: inline-block;
}

#add-friend-search{

    background:url("../images/small arrow.png") no-repeat scroll 88px 2px transparent;
    display:block;
    position:absolute;
    width:332px;

}

#add-friend-search input[type="button"]{

    background:url("../images/search icon.png");
    background-position: center;

}


#add-friend-button{

    border: 1px solid black;
    border-radius: 0 4px 4px 0;
    -moz-border-radius: 0 4px 4px 0;
    -webkit-border-radius: 0 4px 4px 0;
    display: inline-block;
    height: 21px !important;
    margin-right: 33px;
    margin-top: 20px;
    position: absolute;
    right: 0;
    max-height: 31px;    
}

/*Absolutes end */

this is what it looks like in Firefox

and this is what it looks like in chrome

this is the button xcss that contains small, green but I am not supposed to modify this CSS AT ALL

Answer 1

Chrome and Firefox seem to be in conflict with displaying the styles in your classes: small, green and input in conjuction with the style applied for the id add-friend-button.

There are a lot of styles being applied against that button. I would suggest you try to rebuild that form, adding a class at a time and check in each browser until you encounter the difference.

EDIT
The difference between the rendering of the submit button is due to

-moz-box-sizing: content-box;

located in your css class

input[type="button"], button {
    -moz-box-sizing: content-box;
}

turn if off in firebug in firefox and you will see the button take on the same dimensions as in chrome.
