我正在整理一个新的HTML布局的模型。它几乎就在那里，但我的标题栏上出现了恼人的水平滚动问题。
虽然包含元素的宽度为100％，但标题似乎被切割为水平滚动区域。
html,
body {
height: 100%;
width: 100%;
margin: 0;
padding: 0;
background: purple;
}
#wrapper {
width: 100%;
height: 100%;
background: Red;
min-width: 100%;
position: relative;
}
header {
height: 48px;
width: 100%;
min-width: 100%;
background: Orange;
}
我把这个模型放在一个小提琴里： https://jsfiddle.net/8k51k83r/
请注意，如果您水平滚动，标题似乎会结束水平滚动开始的位置。
我在这里做错了什么想法？

您可以添加： public void Currency() {
spin_currency = (Spinner) findViewById(R.id.myspin);
toSpin_currency = (Spinner) findViewById(R.id.myspin1);
ArrayAdapter<CharSequence> adapterC = ArrayAdapter.createFromResource(this, R.array.name,
android.R.layout.simple_spinner_item);
adapterC.setDropDownViewResource(android.R.layout.select_dialog_singlechoice);
spin_currency.setAdapter(adapterC);
toSpin_currency.setAdapter(adapterC);
spin_currency.setOnItemSelectedListener(new spinOne(1));
toSpin_currency.setOnItemSelectedListener(new spinOne(2));
btnConv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
/* if (etInput.getText().toString().trim().length() > 0) {
double cur = Double.parseDouble(etInput.getText().toString()); */
if (from == to) {
Toast.makeText(getApplicationContext(), "Invalid conversion", Toast.LENGTH_LONG).show();
etOutput.setText(null);
} else {
new DownloadData().execute();
