Question

What s the difference between  lt b gt  and  lt strong gt    lt i gt  and  lt em gt  in HTML XHTML  When should you use each

User · Accepted Answer

They have the same effect on normal web browser rendering engines  but there is a fundamental difference between them   As the author writes in a discussion list post   Think of three different situations    web browsers blind people mobile phones    Bold  is a style - when you say  bold a word   people basically know that  it means to add more  let s say  ink   around the letters until they stand out  more amongst the rest of the letters   That  unfortunately  means nothing to a blind person  On mobile phones and other PDAs  text is already bold because screen resolution is very small  You can t bold a bold without screwing something up    lt b gt  is a style - we know what  bold  is supposed to look like    lt strong gt  however is an indication of how something should be understood   Strong  could  and often does  mean  bold  in a browser  but it could also mean a lower tone for a speaking program like Jaws  for blind people  or be represented by an underline  since you can t bold a bold  on a Palm Pilot   HTML was never meant to be about styles  Do some searches for  Tim Berners-Lee  and  the semantic web    lt strong gt  is semantic mdash it describes the text it surrounds  e g    this text should be stronger than the rest of the text you ve displayed   as opposed to describing how the text it surrounds should be displayed  e g    this text should be bold

lt strong gt  and  lt em gt  are abstract  which is what people mean when they say it s semantic    lt b gt  and  lt i gt  are specific ways of making something  strong  or  emphasized   Analogy   Both  lt strong gt  is to  lt b gt  and  lt em gt  is to  lt i gt    as    vehicle  is to  jeep

I use both  lt strong gt  and  lt b gt   actually  for exactly the reasons mentioned in this thread of responses  There are times when bold-facing some text simply looks better  but it isn t   necessarily  semantically more important than the rest of the sentence  Here s an example from a page I m working on right now    Retrieves  lt strong gt all lt  strong gt  books about  lt b gt lacrosse lt  b gt     In that sentence  the word  all  is very important  and  lacrosse  less so--I merely wanted it bold because it represents a search term  so I wanted some visual separation  If you re viewing the page with a screen reader  I really don t think it needs to go out of the way to emphasize the word  lacrosse    I would tend to imagine that most web developers use one of the other  but both are fine-- lt b gt  is most definitely not deprecated  as some people have claimed  For me  it s just a fine line between visual appeal and meaning

They have the same effect  However  XHTML  a cleaner  newer version of HTML  recommends the use of the  lt strong gt  tag  Strong is better because it is easier to read - its meaning is clearer  Additionally   lt strong gt  conveys a meaning - showing the text strongly - while  lt b gt   for bold  conveys a method - bolding the text  With strong  your code still makes sense if you use CSS stylesheets to change what the methods of making the text strong is   The same goes for the difference between  lt i gt  and  lt em gt      Google dixit   http   wiki answers com Q What is the difference between HTML tags b and strong

lt b gt  and  lt i gt  are both related to style  whereas  lt em gt  and  lt strong gt  are semantic  In HTML 4  the first are classified as font style elements  and the latter as phrase elements   As you indicated correctly   lt i gt  and  lt em gt  are often considered similar  because browsers often render both in italics  But according to the specifications   lt em gt  indicates emphasis and  lt strong gt  indicates stronger emphasis  which is quite clear  but often misinterpreted  On the other hand  the distinction between when to use  lt i gt  or  lt b gt  is really a matter of style

While  lt strong gt  and  lt em gt  are of course more semantically correct  there seem definite legitimate reasons to use the  lt b gt  and  lt i gt  tags for customer-written content    In such content  words or phrases may be bolded or italicized and it is generally  not up to us to analyze the semantic reasoning for such bolding or italicizing    Further  such content may refer to bolded and italicized words and phrases to convey a specific meaning    An example would be an english exam question which instructs a student to replace the bolded word

lt strong gt  and  lt em gt  add extra semantic meaning to your document  It just so happens that they also give a bold and italic style to your text   You could of course override their styling with CSS    lt b gt  and  lt i gt  on the other hand only apply font styling and should no longer be used   Because you re supposed to format with CSS  and if the text was actually important then you would probably make it  strong  or  emphasised  anyway    Hope that makes sense

In HTML Lang  these two tags are used as follows  simple text this is test text normal text    simple text this is important textwith normal text  The major diversity between these two HTML tags is that bold makes text only visually look bold  while strong also symbolism hit the respective text as essential and indicates that it is a clear word or text section  This difference is due to the fact that HTML code differentiates between symbolism and physical visual html tags  While the earlier refer to the meaning of the relevant areas  the latter merely define the optical display in browsers  You can check this from here

User · Answer

You should generally try to avoid  lt b gt  and  lt i gt   They were introduced for layouting the page  changing the way how it looks  in early HMTL versions prior to the creation of CSS  like the meanwhile removed font tag  and were mainly kept for backward compatibility and because some forums allow inline HTML and that s an easy way to change the look of text  like BBCode using  i   you can use  lt i gt  and so on    Since the creation of CSS  layouting is actually nothing that should be done in HTML anymore  that s why CSS has been created in the first place  HTML    Structure  CSS    Layout   These tags may as well vanish in the future  after all you can just use CSS and span tags to make text bold italic if you need a  meaningless  font variation  HTML 5 still allows them but declares that marking text that way has no meaning    lt em gt  and  lt strong gt  on the other hand only says that something is  emphasized  or  strongly emphasized   it leaves it completely open to the browser how to render it  Most browsers will render em as italic and strong as bold as the standard suggests by default  but they are not forced to do that  they may use different colors  font sizes  fonts  whatever   You can use CSS to change the behavior the way you desire  You can make em bold if you like and strong bold and red  for example

b or i means you want the text to be rendered as bold or italics  strong or em means you want the text to be rendered in a way that the user understands as  important   The default is to render strong as bold and em as italics  but some other cultures might use a different mapping   Like strings in a program  b and i would be  hard coded  while strong and em would be  localized

HTML Formatting Elements   HTML also defines special elements for defining text with a special meaning  HTML uses elements like  lt b  and  lt i  for formatting output  like bold or italic text   HTML Bold and Strong Formatting      The HTML  lt b  element defines bold text  without any extra importance     lt b gt This text is bold lt  b gt       The HTML  lt strong  element defines strong text  with added semantic    strong  importance     lt strong gt This text is strong lt  strong gt    HTML Italic and Emphasized Formatting      The HTML  lt i  element defines italic text  without any extra   importance     lt i gt This text is italic lt  i gt       The HTML  lt em  element defines emphasized text  with added semantic   importance     lt em gt This text is emphasized lt  em gt

lt b gt  and  lt i gt  are both related to style  whereas  lt em gt  and  lt strong gt  are semantic  In HTML 4  the first are classified as font style elements  and the latter as phrase elements   As you indicated correctly   lt i gt  and  lt em gt  are often considered similar  because browsers often render both in italics  But according to the specifications   lt em gt  indicates emphasis and  lt strong gt  indicates stronger emphasis  which is quite clear  but often misinterpreted  On the other hand  the distinction between when to use  lt i gt  or  lt b gt  is really a matter of style

lt strong gt  and  lt em gt  add extra semantic meaning to your document  It just so happens that they also give a bold and italic style to your text   You could of course override their styling with CSS    lt b gt  and  lt i gt  on the other hand only apply font styling and should no longer be used   Because you re supposed to format with CSS  and if the text was actually important then you would probably make it  strong  or  emphasised  anyway    Hope that makes sense

You should generally try to avoid  lt b gt  and  lt i gt   They were introduced for layouting the page  changing the way how it looks  in early HMTL versions prior to the creation of CSS  like the meanwhile removed font tag  and were mainly kept for backward compatibility and because some forums allow inline HTML and that s an easy way to change the look of text  like BBCode using  i   you can use  lt i gt  and so on    Since the creation of CSS  layouting is actually nothing that should be done in HTML anymore  that s why CSS has been created in the first place  HTML    Structure  CSS    Layout   These tags may as well vanish in the future  after all you can just use CSS and span tags to make text bold italic if you need a  meaningless  font variation  HTML 5 still allows them but declares that marking text that way has no meaning    lt em gt  and  lt strong gt  on the other hand only says that something is  emphasized  or  strongly emphasized   it leaves it completely open to the browser how to render it  Most browsers will render em as italic and strong as bold as the standard suggests by default  but they are not forced to do that  they may use different colors  font sizes  fonts  whatever   You can use CSS to change the behavior the way you desire  You can make em bold if you like and strong bold and red  for example

lt b gt  and  lt i gt  should be avoided because they describe the style of the text  Instead  use  lt strong gt  and  lt em gt  because that describes the semantics  the meaning  of the text   As with all things in HTML  you should be thinking not about how you want it to look  but what you actually mean  Sure  it might just be bold and italics to you  but not to a screen reader

b or i means you want the text to be rendered as bold or italics  strong or em means you want the text to be rendered in a way that the user understands as  important   The default is to render strong as bold and em as italics  but some other cultures might use a different mapping   Like strings in a program  b and i would be  hard coded  while strong and em would be  localized

lt i gt    lt b gt    lt em gt  and  lt strong gt  tags are traditionally representational  But they have been given new semantic meaning in HTML5     lt i gt  and  lt b gt  was used for font style in HTML4   lt i gt  was used for italic and  lt b gt  for bold  In HTML5  lt i gt  tag has new semantic meaning of  alternate voice or mood  and  lt b gt  tag has the meaning of stylistically offset    Example uses of  lt i gt  tag are - taxonomic designation  technical term  idiomatic phrase from another language  transliteration  a thought  ship names in western texts  Such as -   lt p gt  lt i gt I hope this works lt  i gt   he thought  lt  p gt    Example uses of  lt b gt  tag are keywords in a document extract  product names in a review  actionable words in an interactive text driven software  article lead   The following example paragraph is stylistically offset from the paragraphs that follow it    lt p gt  lt b class  lead  gt The event takes place this upcoming Saturday  and over 3 000 people have already registered  lt  b gt  lt  p gt     lt em gt  and  lt strong gt  had the meaning of emphasis and strong emphasis in HTML4  But in HTML5  lt em gt  means stressed emphasis and  lt strong gt  means strong importance   In the following example there should be a linguistic change while reading the word before       lt p gt Make sure to sign up  lt em gt before lt  em gt  the day of the event  September 16  2016 lt  p gt    In the same example we can use the  lt strong gt  tag as follows      lt p gt Make sure to sign up  lt em gt before lt  em gt  the day of the event   lt strong gt September 16  2016 lt  strong gt  lt  p gt    to give importance on the event date   MDN Ref    https   developer mozilla org en-US docs Web HTML Element b  https   developer mozilla org en-US docs Web HTML Element i    https   developer mozilla org en-US docs Web HTML Element em   https   developer mozilla org en-US docs Web HTML Element strong

While  lt strong gt  and  lt em gt  are of course more semantically correct  there seem definite legitimate reasons to use the  lt b gt  and  lt i gt  tags for customer-written content    In such content  words or phrases may be bolded or italicized and it is generally  not up to us to analyze the semantic reasoning for such bolding or italicizing    Further  such content may refer to bolded and italicized words and phrases to convey a specific meaning    An example would be an english exam question which instructs a student to replace the bolded word

Use them only if using CSS style classes is for any reason unconvinient or impossible  like blog systems  allow only some tags to use in posts and eventually embedded styles   Another reason is support for very old browsers  some mobile devices   or primitive search engines  that give points for  lt b gt  or  lt strong gt  tags  instead of analysing CSS styles    If you can define CSS styles  use them

They have the same effect  However  XHTML  a cleaner  newer version of HTML  recommends the use of the  lt strong gt  tag  Strong is better because it is easier to read - its meaning is clearer  Additionally   lt strong gt  conveys a meaning - showing the text strongly - while  lt b gt   for bold  conveys a method - bolding the text  With strong  your code still makes sense if you use CSS stylesheets to change what the methods of making the text strong is   The same goes for the difference between  lt i gt  and  lt em gt      Google dixit   http   wiki answers com Q What is the difference between HTML tags b and strong

In HTML Lang  these two tags are used as follows  simple text this is test text normal text    simple text this is important textwith normal text  The major diversity between these two HTML tags is that bold makes text only visually look bold  while strong also symbolism hit the respective text as essential and indicates that it is a clear word or text section  This difference is due to the fact that HTML code differentiates between symbolism and physical visual html tags  While the earlier refer to the meaning of the relevant areas  the latter merely define the optical display in browsers  You can check this from here
