Why Do I Get A Gap Between Last Element In One Form And First Element In Second Form?

I have this html file: Now, I get a gap between '#nick button' and '#msg input' like shown in this screenshot: So, I made the content window exactly 1000px and took a look at the

Solution 1:

Set font-size: 0 to your form and see the magic!

Well, this is due to the characteristic space between elements when using inline elements - note that you have given display: inline to your form.

The browser styles for the form elements will override the zero font-size or you can do it yourself using font-size: initial.

See demo below:

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  margin: 0;
  background: #ff5;
}

form {
  display: inline;
  font-size: 0;
}

#nick_msg {
  background: #000;
  position: fixed;
  bottom: 0;
  width: 90%;
}

#nick {
  width: 20%;
}

#nick input {
  border: 0;
  padding: 10px;
  width: 10%;
  background: #00f;
}

#nick button {
  border: 0;
  padding: 10px;
  width: 10%;
  background: rgb(130, 224, 255);
}

#msg {
  width: 80%;
}

#msg input {
  border: 0;
  padding: 10px;
  width: 60%;
}

#msg button {
  border: 0;
  padding: 10px;
  width: 10%;
  background: rgb(130, 224, 255);
}

#messages {
  margin: 0;
  padding: 0;
  list-style-type: none;
  background: #fff;
}

<ul id="messages">
  <li>msg</li>
  <li>msg</li>
  <li>msg</li>
  <li>msg</li>
  <li>end</li>
</ul>
<div id='nick_msg'>
  <form id='nick' action="">
    <input id="n" /><button>Join</button>
  </form>
  <form id='msg' action="">
    <input id="m" autocomplete="off" /><button>Send</button>
  </form>
</div>

Solution 2:

I've copied the code here and I think (but I'm not sure), if you're talking about the black little vertical line, you have to add the font-size: 0; to form styling.

form {
    display: inline;
    font-size: 0;
}

Solution 3:

you might want to add change your the add a margin property in the CSS for your form.

form {
    display: inline;
    margin: 0 -0.5em 0 -0.5em;
}

That should get rid of the space between the forms on the left and right (since your forms are on the same line). Hope this helps :)
