How can you put text on top of a &lt;picture&gt; tag? so lets say you have:  &lt;picture&gt;   &lt;source media=&quot;(min-width: 650px)&quot; srcset=&quot;someotherimage.jpg&quot;&gt;   &lt;img class=&quot; w-100 &quot; src=&quot;someimage.j&quot; alt=&quot;The Advocates   &lt;/picture&gt;  So basically its a width 100% image that is supposed to work as a background image, but you want to add some text on top of it, kind of like floating on top of it. How can you do that? Lets say I do something like this:  &lt;picture&gt;   &lt;source media=&quot;(min-width: 650px)&quot; srcset=&quot;someotherimage.jpg&quot;&gt;   &lt;img class=&quot; w-100 &quot; src=&quot;someimage.j&quot; alt=&quot;The Advocates &gt; &lt;div class=&quot;trasnparent-background&quot; &gt;&lt;h2&gt;Hello I am the text over the image&lt;/h2&gt;&lt;/div&gt;  &lt;/picture&gt;  I know the code above wouldn't, but what would be the right way to do it?
I want to overlay one image with another using CSS. An example of this is the first image (the background if you like) will be a thumbnail link of a product, with the link opening a lightbox / popup showing a larger version of the image.   On top of this linked image I would like an image of a magnifying glass, to show people that the image can be clicked to enlarge it (apparently this isn't obvious without the magnifying glass).
How do I calculate CRC32 of a string How do I calculate the CRC32 (Cyclic Redundancy Checksum) of a string in .NET? I'm trying to get my head around mutable vs immutable objects. Using mutable objects gets a lot of bad press (e.g. returning an array of strings from a method) but I'm having trouble understanding what the negative impacts are of this. What are the best practices around using mutable objects? Should you avoid them whenever possible? I have often read that using RSA for encrypting bigger size plaintext is not good solution.  What I understand is that using RSA encrytion is best for small plaintext and most effective if it is smaller than 'bit size' of RSA. For instance, if I use RSA with a 2048 bit size then the plaintext that I can encrypt must be smaller than 256 bytes.  Is this true? What happens if the plaintext is bigger than 256 bytes? Why is there a problem with larger plaintext when performing RSA encryption? Objects disappear when looking through camera Limit of the geometric sequence $\{r^n\}$, with $|r| < 1$, is $0$? Compactness of  Multiplication Operator on $L^2$ Showing that a sequence is monotone and thus convergent Here's the original question:     Let $(a_n)$ be bounded. Assume that $a_{n+1} \ge a_{n} - 2^{-n}$. Show   that $(a_n)$ is convergent.   Okay, I know that if I can show that if the sequence is monotone, I can conclude that it is convergent. But I am not sure how to show that it is monotone.  I know that  $$a_n \le a_{n+1} + \frac{1}{2^n} &lt; a_{n+1} + \frac{1}{n}$$  It looks to me as if it is monotonically increasing but I'm quite not sure how to prove my claim. Any hints would be appreciated. Edit file based on existence of a string I have an input file, say, file1, which appears as follows:  WRITE=2 START=1 SMEAR=0 MIN=6 MAX=100   My problem is to search for the string SMEAR and if the string exists replace the entire line with SMEAR=-5. However, if the SMEAR does not exist, then I need to insert a new line SMEAR=-5. Ultimately the line SMEAR=-5 should appear only once. I can replace the string using sed:   sed -i '/SMEAR/c\SMEAR=-5' file1   Or I can insert the string as a new line    sed -i '10i SMEAR=-5' file1   But how can I combine them based on the existence of the string in the file?  EDIT: Also it would be helpful if I can pass the value of SMEAR as a variable. How can I avoid SSH's host verification for known hosts? If $\sum_{1}^{\infty}(a_n)^3$ diverges, does $\sum_{1}^{\infty}(a_n)$? What HTML tags are allowed on Stack Exchange sites? How to remove the "No front page content has been created yet." message from the front page? I only want blocks on the homepage. Because I don't have any nodes, and I want to keep the homepage as /node I am getting a "No front page content has been created yet." message on my page.  How do I get around this? Coming from Eclipse and having been used to duplicate lines all the time, it's pretty strange finding out that Xcode has no such function. Or does it?  I know it's possible to change the system wide keybindings but that's not what I'm after. When I sum up the sizes of my files, I get one figure. If I run du, I get another figure. If I run du on all the files on my partition, it doesn't match what df claims is used. Why are there so many different figures for the total size of my files? Can't computers add?  Speaking of adding: when I add the “Used” and “Available” columns of df, I don't get the total figure. And that total figure is smaller than the size of my partition. And if I add up my partition sizes I don't get my disk size! What gives? Combining values in one column (or part) when values in another column (or part) match I am trying to pull logs and doing few others things directly. written a small line BASH but not working. I am sure thats with IF Condition.    sed -rne '/21:25:07/,/21:50:07/ p'  server.log.2015-04-21 &gt; /tmp/filename.log ; du -sh  /tmp/filename.log ;  if [`du -sh  /tmp/filename.log` -gt 0] then gzip /tmp/filename.log ; Why was my flag declined? I've recently flagged the following , which I got in the flag queue.   The answer does not seem to attempt to address the question at all. It looks like a comment on one of the other answers (probably Luca's).  It got rejected with the following reason:  declined - flags should not be used to indicate technical inaccuracies,            or an altogether wrong answer   I did not flag this because I thought it was wrong, I flagged it because I didn't think it was an attempt to answer the question. For what it's worth, I don't get what the guy who provided that answer even tried to say.  Was I wrong to flag it? If so why?
