问题 This question already has answers here : How align 2 adjacent divs horizontally WITHOUT float? (5 answers) Closed 5 years ago . I want to know if there exists an elegant way to horizontally align 3 divs without using float css property.

问题 In my JSF 2 - Primefaces 3 web application, I am using <p:panelGrid> and <p:panel> . I have multiple components inside them which are left justified. I need to all to be center align. How can we do this I tried to use div but it does not work. 回答1: Look at the generated HTML output and alter CSS accordingly. If the HTML element which you'd like to center is a block element ( <div> , <p> , <form> , <table> , etc, or forced by display: block; ), then you first need to give it a known width and

问题 I'm trying to align a Label and a NumericUpDown by their text baselines. I'm doing it in code, rather than the designer. How do I get the position of the text baseline? 回答1: // to render text with baseline at coordinates (pt.X, pt.Y) : Font myFont = Label1.Font; FontFamily ff = myFont.FontFamily; float lineSpace = ff.GetLineSpacing(myFont.Style); float ascent = ff.GetCellAscent(myFont.Style); float baseline = myFont.GetHeight(ev.Graphics) * ascent / lineSpace; PointF renderPt = new PointF(pt

问题 I have some code which I'm using to print a receipt from C#. The code below prints OK but I'm struggling with aligning the text left right and center, Graphics graphics = e.Graphics; Font font = new Font("Courier New", 10); float fontHeight = font.GetHeight(); int startX = 0; int startY = 0; int Offset = 0; graphics.DrawString("Welcome to MSST", new Font("Courier New", 14), new SolidBrush(Color.Black), startX, startY + Offset); Offset = Offset + 20; graphics.DrawString("Recept No :" +

问题 I recently got thinking about alignment... It's something that we don't ordinarily have to consider, but I've realized that some processors require objects to be aligned along 4-byte boundaries. What exactly does this mean, and which specific systems have alignment requirements? Suppose I have an arbitrary pointer: unsigned char* ptr Now, I'm trying to retrieve a double value from a memory location: double d = **((double*)ptr); Is this going to cause problems? 回答1: It can definitely cause

问题 I need to align a series of numbers in C with printf() like this example: -------1 -------5 ------50 -----100 ----1000 Of course, there are numbers between all those but it's not relevant for the issue at hand... Oh, consider the dashes as spaces, I used dashes so it was easier to understand what I want. I'm only able to do this: ----1--- ----5--- ----50-- ----100- ----1000 Or this: ---1 ---5 --50 -100 1000 But none of this is what I want and I can't achieve what is displayed on the first

问题 I have a parent DIV (a menu bar) with a random number of child divs. I'm looking for a clean, simple CSS that will always center the child divs horizontally, regardless of their width or the number of divs (as long as they fit inside the parent). I don't want to have to calculate all the widths or use absolute positioning. After looking at several solutions I came up with this code, but the child divs still don't center properly, especially when you fill them with text or images. HTML: <div
