HTML is a markup language used to create webpages, while CSS (Cascading Style Sheets) is used to style those webpages. One of the most important properties in CSS is the margin property, which is used to set the space between an element’s content and its border. In this blog post, we will discuss how to add left and right margins in HTML using CSS.

Understanding the CSS Margin Property

The CSS margin property is used to create space around an HTML element. It can have one, two, three, or four values that represent the top, right, bottom, and left margins, respectively. If the margin property has two values, the first value applies to the top and bottom margins, while the second value applies to the left and right margins. If the margin property has four values, the margins are set separately for each side.

The margin property can accept different types of values such as pixels, ems, rems, percentages, and auto. Pixels and ems are the most commonly used values. A pixel is a fixed unit of measurement, while an em is a relative unit of measurement that is based on the font size of the element. Using ems can make your webpage more responsive and adaptable to different screen sizes.

Adjusting Left and Right Margins

To adjust the left and right margins of an HTML element, you can use the margin-left and margin-right properties. The margin-left property sets the left margin of an element, while the margin-right property sets the right margin of an element. By specifying different values for these properties, you can adjust the spacing between elements in your webpage.

The margin-left and margin-right properties can be used to adjust the position of HTML tables, images, and videos. For example, if you want to move an image to the right of a paragraph, you can use the margin-left property to create space between the paragraph and the image.

It’s important to note that specific sides of the margin can be set using margin-left and margin-right. For example, you can set the left margin of an element to 10 pixels and the right margin to 20 pixels using the following code:

Understanding Padding and the Box Model

Another important property in CSS is the padding property, which creates space around an element’s content. Padding and margin are commonly used for spacing out elements in HTML. The box model is a concept that allows you to add a border around elements and define space. It consists of four parts: content, padding, border, and margin.

When you set the width and height of an element, you are actually setting the width and height of the content box. The padding, border, and margin increase the overall size of the element. For example, if you set the width of a box to 200 pixels and add 20 pixels of padding, the overall width of the box will be 240 pixels.

Helpful Tips and Tricks

Here are some helpful tips and tricks for using the CSS Margin Property :

• The margin property can also accept percentage values. For example, you can set the left margin of an element to 50% to center it horizontally.
• Non-breaking spaces (   ) can be used to create extra spaces before, after, or in-between text.
• The margin-inline-end property corresponds to the margin-top, margin-right, margin-bottom, or margin-left property depending on the defined values. It is used to set the margin on the opposite side of the writing mode.
• It’s important to understand the difference between margin and padding . Margin creates space around an element, while padding creates space within an element.
• The CSS box-sizing property can affect the calculation of an element’s width and height. By default, the width and height properties only set the content box size. By setting the box-sizing property to border-box, the width and height properties will include the padding and border sizes.
• The margin collapse phenomenon can occur when two adjacent margins are touching. In this case, the margins will collapse into a single margin that is equal to the larger of the two margins.
• Negative margins can be used to overlap elements. For example, you can use a negative margin to create an overlap effect between an image and a paragraph.
• The CSS float property can affect the positioning of elements. By setting an element to float left or right, you can create a layout where elements are positioned side-by-side.
• The CSS display property can affect the layout of elements. By setting an element to display inline-block or inline, you can control how it flows within the content of the webpage.
• The CSS clear property can be used to prevent elements from overlapping. By setting an element to clear left, right, or both, you can prevent it from overlapping with other elements that are floated.

Conclusion

In conclusion, the CSS margin property is a powerful tool for adjusting the spacing between elements in HTML. By using the margin-left and margin-right properties, you can easily adjust the left and right margins of HTML elements. Understanding the box model and the difference between margin and padding is crucial for effective use of the CSS margin property. By following the tips and tricks outlined in this blog post, you can master HTML margins and create beautiful, responsive webpages.

margin

The margin CSS shorthand property sets the margin area on all four sides of an element.

Try it

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

/* Apply to all four sides */ margin: 1em; margin: -3px; /* top and bottom | left and right */ margin: 5% auto; /* top | left and right | bottom */ margin: 1em auto 2em; /* top | right | bottom | left */ margin: 2px 1em 0 auto; /* Global values */ margin: inherit; margin: initial; margin: revert; margin: revert-layer; margin: unset; 

The margin property may be specified using one, two, three, or four values. Each value is a , a , or the keyword auto . Negative values draw the element closer to its neighbors than it would be by default.

• When one value is specified, it applies the same margin to all four sides.
• When two values are specified, the first margin applies to the top and bottom, the second to the left and right.
• When three values are specified, the first margin applies to the top, the second to the right and left, the third to the bottom.
• When four values are specified, the margins apply to the top, right, bottom, and left in that order (clockwise).

Values

The size of the margin as a fixed value.

The size of the margin as a percentage, relative to the inline size (width in a horizontal language, defined by writing-mode ) of the containing block.

The browser selects a suitable margin to use. For example, in certain cases this value can be used to center an element.

Description

This property can be used to set a margin on all four sides of an element. Margins create extra space around an element, unlike padding , which creates extra space within an element.

The top and bottom margins have no effect on non-replaced inline elements, such as or .

Horizontal centering

To center something horizontally in modern browsers, you can use display : flex; justify-content : center; .

However, in older browsers like IE8-9 that do not support Flexible Box Layout, these are not available. In order to center an element inside its parent, use margin: 0 auto; .

Margin collapsing

Elements’ top and bottom margins are sometimes collapsed into a single margin that is equal to the larger of the two margins. See Mastering margin collapsing for more information.

Formal definition

• margin-bottom : 0
• margin-left : 0
• margin-right : 0
• margin-top : 0

• margin-bottom : the percentage as specified or the absolute length
• margin-left : the percentage as specified or the absolute length
• margin-right : the percentage as specified or the absolute length
• margin-top : the percentage as specified or the absolute length

Formal syntax

Examples

Simple example

HTML

div class="center">This element is centered.div> div class="outside">This element is positioned outside of its container.div> 

CSS

.center  margin: auto; background: lime; width: 66%; > .outside  margin: 3rem 0 0 -3rem; background: cyan; width: 66%; > 

More examples

margin: 5%; /* All sides: 5% margin */ margin: 10px; /* All sides: 10px margin */ margin: 1.6em 20px; /* top and bottom: 1.6em margin */ /* left and right: 20px margin */ margin: 10px 3% -1em; /* top: 10px margin */ /* left and right: 3% margin */ /* bottom: -1em margin */ margin: 10px 3px 30px 5px; /* top: 10px margin */ /* right: 3px margin */ /* bottom: 30px margin */ /* left: 5px margin */ margin: 2em auto; /* top and bottom: 2em margin */ /* Box is horizontally centered */ margin: auto; /* top and bottom: 0 margin */ /* Box is horizontally centered */

CSS Margins

Margins are used to create space around elements, outside of any defined borders.

CSS Margins

The CSS margin properties are used to create space around elements, outside of any defined borders.

With CSS, you have full control over the margins. There are properties for setting the margin for each side of an element (top, right, bottom, and left).

Margin — Individual Sides

CSS has properties for specifying the margin for each side of an element:

All the margin properties can have the following values:

• auto — the browser calculates the margin
• length — specifies a margin in px, pt, cm, etc.
• % — specifies a margin in % of the width of the containing element
• inherit — specifies that the margin should be inherited from the parent element

Tip: Negative values are allowed.

Example

Set different margins for all four sides of a

element:

Margin — Shorthand Property

To shorten the code, it is possible to specify all the margin properties in one property.

The margin property is a shorthand property for the following individual margin properties:

If the margin property has four values:

• margin: 25px 50px 75px 100px;
  • top margin is 25px
  • right margin is 50px
  • bottom margin is 75px
  • left margin is 100px

  Example

  Use the margin shorthand property with four values:

  If the margin property has three values:

  • margin: 25px 50px 75px;
    • top margin is 25px
    • right and left margins are 50px
    • bottom margin is 75px

    Example

    Use the margin shorthand property with three values:

    If the margin property has two values:

    • margin: 25px 50px;
      • top and bottom margins are 25px
      • right and left margins are 50px

      Example

      Use the margin shorthand property with two values:

      If the margin property has one value:

      Example

      Use the margin shorthand property with one value:

      The auto Value

      You can set the margin property to auto to horizontally center the element within its container.

      The element will then take up the specified width, and the remaining space will be split equally between the left and right margins.

      Example

      The inherit Value

      Example

      div <
      border: 1px solid red;
      margin-left: 100px;
      >

      All CSS Margin Properties

      Property	Description
      margin	A shorthand property for setting all the margin properties in one declaration
      margin-bottom	Sets the bottom margin of an element
      margin-left	Sets the left margin of an element
      margin-right	Sets the right margin of an element
      margin-top	Sets the top margin of an element
