Javascript Row Height

| | | | | | | |

The CSS line-height property determines the line height of various HTML elements. It is commonly used to define the distance between lines of text. Line height can be set to the aid of words - keys, percentages or numeric values.

The CSS line-height property allows developers to set the space between two inline elements on a web page. Developers often use the CSS line-height property to increase or decrease the distance between lines of text on a web page.

This tutorial explains how to use the CSS line-height property. We’ll refer to an example to get you started. By the time you finish reading this tutorial, you will have a good understanding of using the line-height property in your code.

Line-height CSS

The line-height CSS property defines the height of a row box. Line areas are the lines that make up a in CSS area. This method is often used to define the distance between lines of text.

Adjusting the height of lines allows you to indirectly adjust the spacing between lines of text (or other elements) on a web page. It is very similar to formatting text in Microsoft Word with double spacing or 1.15 spacing.

The syntax of the line-height CSS property is as follows:

"lineHeight" refers to a length value that defines the height of an element.

Three types of values ‚Äã‚Äãyou can use with the line-height property are length, number, and percentage:

Value Description Example values ‚Äã‚Äã Result of Example values ‚Äã‚Äã
Length Defines the line height using a specific unit of measure (like em, px, and cm). 10 px, 15 px, 20 px If you specify 10px, the height of line will be 10px.
Number Sets the height of the line to be a multiple of the font size. 1, 1,8, 2 If the font size is 10px, the row height will be 10px, 18px and 20 px respectively. < / tr>
percentage Defines the row height as a percentage of the item’s font size . 30%, 50%, 110% If the font size is 10px, the row height will be 3px, 5px, and 11px respectively.

Alternatively, you can specify the keyword "normal.‚" This keyword specifies the use of the default browser. This value is usually around 1.2, depending on the browser used by user.

If you apply the line-height property to a box, all text in that box will use the height of the .line box you specified.

A note on accessibility

Changing the line spacing is a common use of the line-height property. This is because you always want to make sure that there is enough space between lines. If there is not enough space between the lines, the text may be difficult to read.

a text difficult to read a particularly serious effect on the visually impaired. the accessibility should always be taken into account account when creating a website.

When using a number to set the row height of an element in CSS, you should not use values ‚Äã‚Äãless than 1.5. This is because row height values ‚Äã‚Äãless than 1.5 can make your site more difficult for visually impaired readers to use.

CSS Example for Row Height

Suppose you are designing an "About Us‚" Page for a local cooking club website. The page contains a heading followed by a paragraph of text describing a description of the club.

We want our text to be properly spaced. So we decide to set the line height of the text paragraph on the web page to 1.6 rem. We can do this using this code:

Our code returns: Click ’Image in the code editor above to see the output of our HTML / CSS code.

In our HTML file, we have defined an " About Us " header using an

tag . So we wrote a description of Fantastic Chefs and included it in the HTML

tag .

In our CSS file, we have defined a rule. Our rule uses two CSS properties. We set the row height to 1.6rem and the font size to 16px for all HTML


The "rem" unit of measure we used with the line-height property defines a row height relative to the font size of the root element. "rem" mean s "root element". So, because our font size was 16px, the line height of this paragraph of text was 25.6px (16px * 1.6).

The text in the above paragraph is well spaced and does not overlap.

We could also apply row height to our tag to the values ‚Äã‚Äãwe specified. This would mean that our titles and our

tag would be affected.


The CSS line-hei The ght property defines the height of a line box. Typically, this property is used to set the spacing between lines of text in a paragraph or heading. The row height can be set using the normal keyword, a percentage, a length, or a numeric value.

This tutorial has discussed the basics of the CSS row height property and how you can use it in code. You now have the knowledge to start using the CSS line-height property like an expert !

Javascript Row Height __del__: Questions

How can I make a time delay in Python?

5 answers

I would like to know how to put a time delay in a Python script.


Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).


Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

Removing white space around a saved image in matplotlib

2 answers

I need to take an image and save it after some process. The figure looks fine when I display it, but after saving the figure, I got some white space around the saved image. I have tried the "tight" option for savefig method, did not work either. The code:

  import matplotlib.image as mpimg
  import matplotlib.pyplot as plt

  fig = plt.figure(1)
  img = mpimg.imread(path)

  extent = ax.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
  plt.savefig("1.png", bbox_inches=extent)


I am trying to draw a basic graph by using NetworkX on a figure and save it. I realized that without a graph it works, but when added a graph I get white space around the saved image;

import matplotlib.image as mpimg
import matplotlib.pyplot as plt
import networkx as nx

G = nx.Graph()
pos = {1:[100,120], 2:[200,300], 3:[50,75]}

fig = plt.figure(1)
img = mpimg.imread("image.jpg")

nx.draw(G, pos=pos)

extent = ax.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
plt.savefig("1.png", bbox_inches = extent)


Answer #1

You can remove the white space padding by setting bbox_inches="tight" in savefig:


You"ll have to put the argument to bbox_inches as a string, perhaps this is why it didn"t work earlier for you.

How to set the margins for a matplotlib figure?

Reduce left and right margins in matplotlib plot


Answer #2

I cannot claim I know exactly why or how my “solution” works, but this is what I had to do when I wanted to plot the outline of a couple of aerofoil sections — without white margins — to a PDF file. (Note that I used matplotlib inside an IPython notebook, with the -pylab flag.)

plt.subplots_adjust(top = 1, bottom = 0, right = 1, left = 0, 
            hspace = 0, wspace = 0)
plt.savefig("filename.pdf", bbox_inches = "tight",
    pad_inches = 0)

I have tried to deactivate different parts of this, but this always lead to a white margin somewhere. You may even have modify this to keep fat lines near the limits of the figure from being shaved by the lack of margins.
