我正在使用第三方css库来进行样式设置，但我想min-height为特定的库指定不同的样式div。
的div是使用themeRow具有许多属性和套类：

min-height: 200px

就我而言，这太大了，我想设置一个不同的值，即

min-height: 75px

所以我已经定义了一些内联，css但是在渲染时div仍然排除了我的值，并且仍然在min-height: 200px

有什么办法可以告诉css我使用我的值而不是第三方值？

<style>
.bannerHeight {
    min-height: 75px;
}
</style>


<div class="themeRow bannerHeight"></div>

是否可以使用普通的javascript确定用户点击进度条的值/位置？

目前,我可以检测到元素上的点击,但只能获取栏的当前位置,与用户的点击无关.

http://jsfiddle.net/bobbyrne01/r9pm5Lzw/

HTML

<progress id="progressBar" value="0.5" max="1"></progress>

JS

document.getElementById('progressBar').addEventListener('click', function () {
    alert('Current position: ' + document.getElementById('progressBar').position);
    alert('Current value: ' + document.getElementById('progressBar').value);
});

有什么想法可以opengl进一步调试此错误吗？1281

我正在从文件加载源代码，进行编译，链接，然后尝试在之后检查错误 glUseProgram

在我对象的绘制方法中..

log.info(gl2.glIsProgram(shaderProgram)); // true
gl2.glUseProgram(shaderProgram);

int error;
while ((error = gl2.glGetError()) != GL2.GL_NO_ERROR) {
    throw new RuntimeException("glUseProgram" + ": glError " + error);
}

输出..

[13:38:08] INFO (IARectangle.java:99) - true

目前desktop应用程序版本很好，按钮缩放得很好，但是当我部署到android它们时，它们很小并且几乎无法使用。

是否可以使用 检索body内容express？

我开始尝试，body-parser但这似乎不适用于GET. 有没有可以工作的模块？

var express = require('express'),
  bodyParser = require('body-parser'),
  PORT = process.env.PORT || 4101,
  app = express();

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.route('/')
  .get(function(req, res) {
    respond(req, res, 'GET body contents:\n');
  })
  .post(function(req, res) {
    respond(req, res, 'POST body contents:\n');
  });

app.listen(PORT, function(err) {
  if (err) {
    console.log('err on startup ' + err);
    return;
  }
  console.log('Server listening on port ' + PORT);
});
