align horizontal navigation menu - css

Question

i have a horizontal navigation bar.
i wish to add a search bar to the navigation bar, but when i insert it, my navigation bar is misaligned.
https://jsfiddle.net/r6ntxg2f/
as you can see my menu is hovering above the green line, and the right side menu is hovering even more. i wish to align the whole menu to the green line.
<li id="searchbar">
<form id="search" method="post" style="">
<input id="bb" type="text" style="" />
<input id="cc" type="submit" value="Search" style="" />
</form>
</li>
this is how it is without search. https://jsfiddle.net/q476f585/ (working)

Answer 1

Seems like your sizes and padding was causing the issue, see the jsfiddle for an updated solution. All I done was updated the padding and display style. For the bottom border you will have to ensure that the other padding on the first two buttons are correct.

Answer 2

You can fix the issue by adjusting padding. Here is the working code.
ul#menu_left {
position: relative;
left: 100px;
width: 75%;
font: 75% verdana;
list-style-type: none;
padding: 10px 10px 5px 10px;
border-bottom: 1px solid green;
}
ul#menu_right {
padding-right: 10px;
float: right;
padding-top: 2px
}
ul#menu_left li {
display: inline;
}
ul#menu_left li a {
padding: 6px 4px;
border-bottom: 1px solid green;
text-decoration: none;
color: white;
background-color: green;
}
ul#menu_left a:hover {
color: black;
background: yellow;
border-bottom: 1px solid yellow;
}
li#searchbar {
background-color: green;
padding: 6px 4px;
border-bottom: 1px solid green;
}
li#searchbar form {
display: inline;
}
li#searchbar input {
width: 50px;
}
<ul id="menu_left">
<li><a id="tab1" href="#">The We</a>
</li>
<li><a id="tab2" href="#">Book</a>
</li>
<li><a id="tab3" href="#">Tab</a>
</li>
<li id="searchbar">
<form id="search" method="post">
<input id="bb" type="text" />
<input id="cc" type="submit" value="Search" />
</form>
</li>
<ul id="menu_right">
<li><a id="tab5" style="" href="#">Up</a>
</li>
<li><a id="tab6" href="#">Contact</a>
</li>
</ul>
</ul>
