How To Set Top Margin In Javascript

| | | | | |

Adding spaces between elements of a web page is a crucial part of designing user experiences that are both aesthetic and functional. Margins are used to create a blank area around an HTML element to separate the element from other objects on the web page.

The CSS margin property and its four sub-properties are used to define a margin around an element in HTML.

This tutorial will explain, with references and examples, how to use the margin property and its sub-properties to create a margin around an element in CSS. By the end of this tutorial, you will have a good understanding of applying a margin to a web element using CSS.

CSS Margin

The CSS Margin property is used to create a space around an element. This space allows you to easily separate multiple elements on a web page, apart from any border.

In CSS, the margin property is shorthand for four sub-properties. These sub-properties are used to set the top, right, bottom, and left margins of a web item.

Each element of a web page consists of one or more panes. The elements use the box template to delimit how the box is displayed on the web page.

Margins are one of the main components of the box model and exist at the outermost level of the box model. In the graphic below, you can see that margins are applied outside the borders in an HTML element:

this tutorial, we & rsquo; We will focus on property margin. If you want to know more about the various components of the box model, you can read our articles on borders and CSS filling.

Individual sides with CSS margin

The following properties are used to define the margin on either side of a web element:

  • margin-top
  • margin-right
  • margin-bottom
  • margin-left

These properties allow you to set the margin for only one side of an element. Each of these properties accepts one of four values ‚Äã‚Äãto determine the size of the margin. They are:

  • length specifies a margin using px, em, or some other CSS length measure.
  • percentage (%) specifies a margin as a percentage of the width of the element to which the margin is applied.
  • auto tells the browser to calculate the margin.
  • inherit specifies that the margin should be inherited from its parent element.

Let’s look at an example to discuss how the margin sub-properties work.

Suppose you are designing a box and want to include some margins around the box to separate it from other elements on the web page. Our box should have a top margin of 50px, a left margin of 30px, a right margin of 40px, and a bottom margin of 50px. We could create this box using the following code:

Our code returns:

 1 VMct IIxkR0JYvcrf07 Q5Yl2sramBIlxrROKsCIKRJ21FRdo Yqi4HIHnILVQhA2koZ8UUjyuGOS061bqg9jrphw 0VlQAQ2E 6TrWyoNTI83PIKpb3mUzQ56mI7WWDE2asGA

in our code, we created two boxes. the first box set with a the tag is a

tag , which contains the text This is a box >. Our

has the class name box, which means that the style of box in our CSS file is applied to our

element tag .

Our

tag was given a top margin of 50 pixels, a left margin of 30 pixels, a right margin of 40 pixels, and a bottom margin of 40 pixels. We also gave our

tag a solid red border that is 1 pixel wide. As you can see in the above image, our margin has created a gap between the edge of our box

and our blue box. If we didn’t have margins, those boxes would be closer together.

Shortcut for CSS Margins

In the example above, we used four lines of code to specify the margins we wanted to apply to our box. We can make our code more efficient by using the margin property.

The margin property is a shortcut to the four sub-properties described above. This property allows you to specify the margins of a box on a single line of code, rather than on multiple lines.

The syntax you use to shorten the margins depends on the number of values ‚Äã‚Äãyou specify. The minimum number of values ‚Äã‚Äãthat you can specify is one and the maximum is four. Let’s look at an example of using the shortened margin property in all potential use cases.

Four values ‚Äã‚Äã

Instead of using the individual margin sub-properties to create a box with four different margin values, you can use the shortened margin property and specify four values .

If you specify four values ‚Äã‚Äãwith the margin property, the order in which your margins will appear is:

  • The first value is the top margin.
  • The second value is the right margin.
  • The third value is the bottom margin.
  • The fourth value is the left margin.

Suppose you want to create a box with a top margin of 25 pixels, a right margin of 25 pixels, a bottom margin of 50 pixels, and a left margin of 60 pixels. We could do it using this code:

Our code returns:

 TYRGhIuWYMB6xDZARsQntmnNcqq4Y WyNquRCyTGNM2Qf0 UIGBcYkn9g1qPlDsDjNa0vzrwA80I Dz PfQKKndYR M5mhVNnHRtB2LkkDiZJ NQmimplTnBVzuM6Y2oNp6WT0Gw

In our example, we created an inner box with a different margin on each edge based on the values that we specified above. We have also surrounded our inner box with a solid red margin that is 1 pixel wide. So, let’s reuse the code from our blue box from earlier to illustrate the size of the margins we applied to our box.

Three values ‚Äã‚Äã

If you want to have another top and bottom margin, but use the same margin for the left and right sides of a box, you can ez use the margin property and specify three values.

The order in which the three specified margins are applied to a box is as follows:

Let’s say we want to create a box with a 50px margin at the top of the box, a 25px margin to the left and right of the box, and a 60px margin at the bottom of the box. box. We could create a box with these margins using the following code:

Our code returns:

 TYRGhIuWYMB6xDZARsQntmnNcqq4Y WyNquRCyTGNM2Qf0 UIGBcYkn9g1qPlDsDjNa0vzrwA80I Dz PfQKKndYR M5mhVNnHRtB2LkkDiZJ NQmimplTnBVzuM6Y2oNp6WT0Gw

In our example, we created an inner box with a different margin each edge according to the values ‚Äã‚Äãwe specified above. We have also surrounded our inner box with a solid red margin that is 1 pixel wide. Additionally, we are reusing the code from our blue box from earlier to illustrate the size of the margins we applied to our box.

Three values ‚Äã‚Äã

If you want to have a different top and bottom margin, but use the same margin for the left and to the right of a box, you can use the margin property and specify three values.

The order in which the three specified margins are applied to a box is as follows:

Suppose we want to create a box with a margin of 50 pixels at the top, a margin of 25 pixels to the left and right of the box, and a margin of 60 pixels at the bottom. We could create a box with these margins using the following code:

Our returns the code:

JkpuJwggQLOfPFjO4JQf4U2c6JMCcuKkePQm45ewqxzlrwspqdHp0n6S4yh3zhiIcmwWLWIDBoYJdk INwHyRrIVzG658BugZ5X3Nq0TPSKdX 63aGIfK SikG2BAoFD1YByBQPJ

As you can see, the left and right sides of our inner box have the same value of the margin -25px -ei upper and lower sides have their margins ( 50px and 60px respectively).

In our code, we’ve also defined a red border around our inner box to illustrate where our margins are applied. We’re also reusing the code from our first example to create a blue box that shows the space our margins created around the inner box.

Two values ‚Äã‚Äã

If you want a box to have the same margin value for the top and bottom of the box and another value for the right and left sides of the box box, you can use the margin property and specify two values.

The order in which the specified values ‚Äã‚Äãare applied to an element is:

Suppose you want to create a frame with a vertical margin of 50 pixels and a horizontal margin of 30 pixels. You can create this box using the following CSS style:

Our code returns:

 UcEArhfhk3NFr9ySo1oaK7fbfFKkAaKDzDpRFzEgdz0ofnqvxWsAfVyKlI4 R8XVZ9kwyZr9rXqiowsfHsnsWgwKvg2D5pNLIgfQlpC LYwutIiUb11DS65gIssboSPTjqbfYLpK

at the top and bottom of an area has a margin of 50px, and left and right sides is a margin of 30px.

our code, we also specified a red border around our inner box to show the size of our margins. We also reuse the code from our previous examples to create a blue box that shows the space created by our margins between the inner boxes. and outer.

One value

If you want each side of a box to have the same margin, you just need to specify a value when using the margin property . the value you specify will be the margin finished around all edges of a box.

Let’s say we want to create a box with a single margin of 50 pixels around all of the edges. You can do this using this code:

Our code returns:

 IAmvlCgz8BRH I9K3lbHw S74Ec X90F0wfyHwRTwKyn2uVOHtxIcxVmyx Q10P QhrIUqW4wr2Ekxdi3Flfca9xJtTnoDxDlUIt the 3JhlNScmNyVAHRmpaipih3ru4kianr360

Each edge of our box has a margin of 50px. We specified a red border around our box to show that our margins are applied to the outside of the box border and we also created a blue box where our red box is positioned to better illustrate our margins.

Inherited margin

The inherit value is used to inherit a margin from a parent element.

To set the margin of an inner box to be the same as the margin of an outer box, we can use the inheritance value. The inheritance value is useful because if you change the margin of the parent element, the margin of the child element - the box in the parent element - will automatically adjust.

Suppose we design a frame whose parent element has a left margin of 50px. We want the box contained in our parent element to have the same margin value. We could use the following code to do this:

Our code returns:

 GCBLp3bZjxAYX5vTMqPj9fiuwZM CQJvZCXA3crpWmNubIE LBjxDomWVhtB46MkgbOoyG8 L1SoiDXY Wee6iQBPLnW8PMlm3z6oLMSMuHYrvOG0eKHoMjPfAzpDbgsMUAo8sPj

our outer box (the one with a blue border) has a left margin of 50px. Additionally, our inner box (the one with a red border) has a left margin of 50px, inherited from its parent element.

Auto Margin

The auto value is used to center an element horizontally in its container.

The automatic value will cause an inner element to occupy a certain width based on the value you set, so that the remaining space will be divided between left and right.

Let’s say you created a box that is 250px wide inside a box that is 500px wide. If you used the auto keyword to create a margin, a margin of 125px will be applied to both the left and the right of the box. We calculated this using the following formula:

In this case, we used the following sum to calculate the side of our auto-generated margins:

The answer to this problem is 125, which is the margin value that will be applied to both left and right margins of a box. Here is an example of a box using these dimensions:

Our returns code:

 KBCZc2dy4OFsK0Can8gMuV T1Y6RKAe2zHY50JDgV6oCOn F63UzigJR5I12NB 50qRG7FUw8Btfg AM 9f6ldxLWyfYM0sI0gl9IaCHr5HByGLhHJKr5HByGLhHJKmp> an inner edge of our box> </and right . in other words, our inner box is centered horizontally. This is because we used the margin value : auto to specify our margin for our inner box.

Our inner box has no margins on the top or bottom edges, as we didn’t specify any for our example.

Conclusion

The CSS margin property is used to create a space between the border of an element and other elements on the web page.

Referring to examples, this tutorial demonstrates how to use the CSS margin property and how to use its four sub-properties to create spaces between the border of an element and other elements on a page Web. You are now equipped with the tools you need to start using CSS margin property like a pro!

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).

2973

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)
  plt.imshow(img)
  ax=fig.add_subplot(1,1,1)

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

  plt.axis("off") 
  plt.show()

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

fig = plt.figure(1)
img = mpimg.imread("image.jpg")
plt.imshow(img)
ax=fig.add_subplot(1,1,1)

nx.draw(G, pos=pos)

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

plt.axis("off") 
plt.show()
228

Answer #1

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

plt.savefig("test.png",bbox_inches="tight")

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

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.gca().set_axis_off()
plt.subplots_adjust(top = 1, bottom = 0, right = 1, left = 0, 
            hspace = 0, wspace = 0)
plt.margins(0,0)
plt.gca().xaxis.set_major_locator(plt.NullLocator())
plt.gca().yaxis.set_major_locator(plt.NullLocator())
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.
