问题 If I am having two divs in a parent div and and all three divs have float left. What I have to do is to align center the two child divs without removing float left. 回答1: Use display: inline-block instead of float: left on child divs and you can give text-align: center to the parent div. 回答2: Let me see if i have understood,so you have something like this: <div id="parent" style="float:left;"> <div id="child1" style="float:left;"></div> <div id="child2" style="float:left;"></div> </div> And if

问题 I'm learning Angular2, so please forgive me if I'm asking a stupid question.

问题 I have been at this for hours trying to get these images to display. I didn't want to resort to posting a question on stackoverflow but it seems like the best option right now.

问题 This is the iframe I create to autostart a video (music, mostly) in my blog : < iframe width="140" height="105" src="https://www.youtube.com/embed/tGzl_AB4poI?rel=0&showinfo=0&autoplay=1" frameborder="0" allowfullscreen></iframe> It's all perfect. The only problem is the Audio, because the Volume is too high and I would decrease it- So I added this part on my code : "&player.setVolume(5)" The final code, then, is this one: < iframe width="140" height="105" src="https://www.youtube.com/embed

问题 I'm trying to format a MySQL formatted date (YYYY-MM-DD) and wish to display the month and year, "September 2012" for example. My code: <?php echo htmlspecialchars($row["date"], ENT_QUOTES, "UTF-8"); ?> Does anyone know how I can accomplish this? 回答1: You can use DateTime to format your date how you'd like: $date = DateTime::createFromFormat('Y-m-d', $row["date"]); echo htmlspecialchars($date->format('F Y'), ENT_QUOTES, "UTF-8"); So with a date like this: $row['date'] = '2012-09-25'; This

问题 I'm trying to build a basic documentation site using asciidoctor. One thing I am struggling with is how I can inject a standard site header (a banner with a logo and top-level navigation) into each documentation page. I render my asciidoc directly to html from the command line.

My early attempts involved using docinfo.html but that gets
