In this CSS tutorial, we’ll see how to center text and lock elements. There are several tips you can use to center elements horizontally and vertically in a layout.

To center aligned text in a larger element, use text-align: center; as shown below:

I am a div

And all the text is centered by text-align: center

Alignment central block elements:

The centering of block elements is best illustrated using the tag of an HTML document. What you need to do is check the overall width of the container, then set the margin to auto:

I’m a div

And all the text is centered by text-align: center

Align the image to the center:

To center an image, in the CSS selector, modify the mass display then control the width of the image element, using % or px. Set margin to auto:

I’m a div

And all the text is centered by text-align: center

To center the underlying image, change the display to block then set the margins to auto, check the width using px or%

Center vertically and horizontally in a div:

padding:

To center vertically in a - you can then use text-align: center to center the paragraph horizontally: < br>

I’m a div

And all the text is centered by text-align: center

To center the underlying image, change the display to block then set the margins to auto, check the width using px or%

line-height:

You can also set line-height to the height of the block element that you center with the text -align: center to align the element to the center. If you have multiple lines, use line-height on parent and child and add vertical-align: middle and display: inline-block to the child: < br>

transform:

Another way to center elements is to use position and transformation. Place the parent in position: relative, the child in absolute position. The child element will need to be positioned top and left at 50%, then we’ll use the transform property to adjust the text in the div. We’ll talk more about this property in another article, so it’s okay if it’s not 100% clear at the moment:

flexbox:

Finally, we can center the elements using flexbox. Set display: flex to the parent element of the children you want to center, then use align-items and require-content to center it:

These are the most common ways to solve the element centering problem in Layout.

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 Central Javascript Text, check other absolute-related topics.
