When designing your layout with CSS, you often place elements up / down or left / right. The z-index allows elements to be moved to a third dimension on the Z axis, with an overlapping effect (one on top of the other).

z -index accepts the keyword auto or an integer. These are all valid statements:

Note : to apply the z-index, you must also position the elements, using the Position property relative, absolute or fixed. If no position is specified it will be like the application z-index: auto and no stack context will be applied

With that in mind, let’s take a look as an example. .

Let some guinea pigs

You can check this example at Codepen . Play with him and the program with me!

We are going to place two guinea pigs, or Cuys ( which sounds much nicer). Imagine it is summer, it is over 90 degrees outside. Cuy # 1 will be placed inside a lake, will have fun. Cuy # 2 is very lazy so we have to give him some coffee to wake him up! Next, we’re going to stack our Cuy # 2 with the coffee so it can drink.

Without positioning or CSS our images look something like this:.

the idea is to create an overlay context using z-index, then place images above the lake and a cafe.

Additionally, remember we need to add positioning to our elements in order to apply the z-index. Let’s go ahead and place our Cuy # 1:

Where the hell is our friend? We’re going to go ahead and add more stacking context so it’s above the lake:

Yes! Our Cuy is above the lake. Now we need to add some padding to place it inside the lake, but I’ll let you play with this

Now that we know how to create an overlay context using z-index, we can place our second animal very easily:

Again the padding will be for the exact positioning of the image and the width is only used to specify the size of our boyfriend. happy and feel refreshed:

Conclusion

Playing with z-index gives way to interesting ideas of setting page. On the Codepen I have also provided a second example of the pop design and the cat positioned with z-index on top of everything. Check it out!

Remember that you still have items in your place or z-index will not work. Try to play around with Codepen by removing the placement and see it for yourself .

Another recommendation is that you should apply z-index to sibling elements. In our examples our images are not nested and were sisters (side by side). If you have deeply nested elements, z-index may not work as expected . So keep that in mind.

Javascript Index Z absolute: Questions

How to get an absolute file path in Python

3 answers

izb By izb

Given a path such as "mydir/myfile.txt", how do I find the file"s absolute path relative to the current working directory in Python? E.g. on Windows, I might end up with:

"C:/example/cwd/mydir/myfile.txt"
877

Answer #1

>>> import os
>>> os.path.abspath("mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

Also works if it is already an absolute path:

>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

How to check if a path is absolute path or relative path in a cross-platform way with Python?

3 answers

UNIX absolute path starts with "/", whereas Windows starts with alphabet "C:" or "". Does python have a standard function to check if a path is absolute or relative?

Answer #1

os.path.isabs returns True if the path is absolute, False if not. The documentation says it works in windows (I can confirm it works in Linux personally).

os.path.isabs(my_path)

How to join absolute and relative urls?

3 answers

I have two urls:

url1 = "http://127.0.0.1/test1/test2/test3/test5.xml"
url2 = "../../test4/test6.xml"

How can I get an absolute url for url2?

139

Answer #1

You should use urlparse.urljoin :

>>> import urlparse
>>> urlparse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"

With Python 3 (where urlparse is renamed to urllib.parse) you could use it as follow:

>>> import urllib.parse
>>> urllib.parse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"

We hope this article has helped you to resolve the problem. Apart from Javascript Index Z, check other absolute-related topics.
