Question

简而言之，这是我的current code，我希望它看起来像this。

如何通过修复css来实现这一目标？

如您所见，向导的右侧未与input的右侧对齐（向导的长度不等于输入的长度）。

我需要向导的最后一部分（使用messages）与input的右侧对齐。我怎么能这样做？

Answer 1

您必须将最后一项向右浮动，但这可能不是最佳解决方案。

.nav-wizard > li:last-child {
    float: right;
}

Answer 2

如果您希望它伸展到右边缘，您应该制作/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package Model; import java.io.File; import java.io.IOException; import java.util.logging.Level; import java.util.logging.Logger; import weka.core.Instances; import weka.core.converters.ArffSaver; import weka.core.converters.CSVLoader; /** * * @author sanketh */ public class testClass { public void createArff(String Filename) { try { String path = Filename.substring(0, Filename.length() - 3); System.out.println("new path:" + path); String[] args = new String[2]; args[0] = path + "csv"; args[1] = path + "arff"; // load CSV CSVLoader loader = new CSVLoader(); loader.setSource(new File(args[0])); Instances data = loader.getDataSet(); System.out.println(data); // save ARFF ArffSaver saver = new ArffSaver(); saver.setInstances(data); //saver.setFile(new File(args[1])); saver.setFile(new File("h:\\abc.arff")); saver.writeBatch(); } catch (IOException ex) { //System.out.println("Please try with some other test data!"); // attribMap.resultLog="Please try with some other test data!"; Logger.getLogger(GenerateFile.class.getName()).log(Level.SEVERE, null, ex); } } public static void main(String[] args) throws Exception { String nepath="H:\\file.csv"; testClass t1=new testClass(); t1.createArff(nepath); } }项目Exception in thread "main" java.lang.NullPointerException at java.io.Writer.<init>(Unknown Source) at java.io.PrintWriter.<init>(Unknown Source) at java.io.PrintWriter.<init>(Unknown Source) at weka.core.converters.ArffSaver.writeBatch(ArffSaver.java:187) at Model.testClass.createArff(testClass.java:39) at Model.testClass.main(testClass.java:65)和/* * If 'main' is defined we clear that definition * to get our default 'main' function back. */ #ifdef main # undef main #endif /* main */ int main(int argc, char** argv) { // ... return 0; }。虽然ul项应为display: table;。
