如何消除2个内容之间的小差距？

Question

  *, *:before, *:after {-moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box;}
input[type="text"] {
   
    background-color: green;
    padding: 7px;
    font-family: helvetica, arial, sans-serif;
    font-size: 1.2em;
    margin-bottom: 20px;
    display: block;
    border: solid 2px #bbb;
    color: white;
}
input[type="submit"] {
    background-color:blue;
    font-family: helvetica, arial, sans-serif;
    font-size: 1.0em;
    font-weight:bold;
    padding: 7px;
    color: white;
}
input[type="submit"]:hover {
    background-color: #ff379f;  
    color: #fafafa;
}
#subscription-email-text-field {
    vertical-align: top;
    display:inline-block; 
    font-size:0.9em; 
    font-weight:400; 
    border:0; 
    width:250px;
    height:32px;
    margin:0;
}
#subscribe-button {
    display:inline-block;
    border: 1px solid black;
    border-width:0px 0px 0px 1px;
    margin:0;
    height:32px;
}

<input type="text" id="subscription-email-text-field" name="email" placeholder="box 1">
<input type="submit" id="subscribe-button" value="subscribe">

我有一个文本框和一个按钮，我想让它内联。但不知何故，他们之间存在一点差距。

我正在尝试设置填充和边距，但它不会改变

如何删除它？所以它看起来像这样

Answer 1

删除元素之间的空格。在两个public class MainActivity extends Activity { Button button1; Button button2; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); button1 = (Button) findViewById(R.id.button1); button1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { setContentView(layout1); } }); button2 = (Button) findViewById(R.id.button2); button2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { setContentView(R.layout.layout2); } }); } } 元素之间有一个空格，因此您将获得不需要的空间。

尝试以下代码段

input

  *, *:before, *:after {-moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box;}
input[type="text"] {
   
    background-color: green;
    padding: 7px;
    font-family: helvetica, arial, sans-serif;
    font-size: 1.2em;
    margin-bottom: 20px;
    display: block;
    border: solid 2px #bbb;
    color: white;
}
input[type="submit"] {
    background-color:blue;
    font-family: helvetica, arial, sans-serif;
    font-size: 1.0em;
    font-weight:bold;
    padding: 7px;
    color: white;
}
input[type="submit"]:hover {
    background-color: #ff379f;  
    color: #fafafa;
}
#subscription-email-text-field {
    vertical-align: top;
    display:inline-block; 
    font-size:0.9em; 
    font-weight:400; 
    border:0; 
    width:250px;
    height:32px;
    margin:0;
}
#subscribe-button {
    display:inline-block;
    border: 1px solid black;
    border-width:0px 0px 0px 1px;
    margin:0;
    height:32px;
}
