Why is inline css used

Instead of writing a rule in a separate style sheet, you can add the style directly to the paragraph whose color you want to change. The rules applied inline will override any styles applied in an internal or external style sheet. Suppose we want to change the text color of a single heading on a web page to green. We could do so using the following code:.

The above code sets the CSS font color of our heading to green. Because we only want our style to apply to this heading, we have added it directly in using CSS inline.

CSS inline styles are used to preview changes to a web page or to add elements to one element on a page. Inline styles are used to preview specific changes because you can work with a specific element instead of all elements that meet a CSS selector. Inline styles are used to add CSS rules to one element on a web page.

So, if you want to set the width of a paragraph of text to px, you could do so. But if you wanted to set the width of multiple paragraphs of text to px, you should use another method of styling.

When used sparingly, inline CSS is a good way to apply styles to elements on a web page. However, overuse of CSS inline can easily result in messy code. Inline styles are difficult to update because you have to manually change each style.

Styles in a style sheet, on the other hand, can use broad selectors. Community Bot 1 1 1 silver badge. Bruno Jennrich Bruno Jennrich 4 4 silver badges 4 4 bronze badges. I think this really is the correct answer. The mantra of "separation of concerns" is just one criteria.

The key aspect is whether or not the style is reusable at semantic level, not merely syntatic. If that's the case, then the sheet makes sense. It dependes on the elements being semantically the same.

A "color" style usually is semantically related part of the theme , and usually would go in a sheet. Ashish Gupta Ashish Gupta Noah Beach Noah Beach 41 1 1 bronze badge. Ian Mercer Ian Mercer True, and if you have to enable this CSP you have a lot of work to provide the nonce values or to remove the inline styles and replace them with CSS.

Having implemented this, individual one-time-only styles can be manually coded where needed. Roger Stevens Roger Stevens 11 2 2 bronze badges.

Even though I totally agree with all the answers given above that writing CSS in a separate file is always better from code reusability, maintainability, better separation of concerns there are many scenarios where people prefer inline CSS in their production code - The external CSS file causes one extra HTTP call to browser and thus additional latency.

A much bigger problem , really: Embedding the CSS means every page request must contain that CSS, whereas otherwise, the browser can cache it. You are right. That's why we inline CSS when the code size is very small so that it does not cause too much overhead on page size. There is a very interesting article on Yahoo!

Perf guidelines page developer. While it's likely that a user accesses your site with an empty cache, it's unlikely that they're going to access your page with an empty cache. Unless the page is single-use i. These days many modern webpages are designed as Single Page Application, the full page gets loaded only the first time.

Next time onwards the page is changed through AJAX call. So even if the page is multiuse the external CSS is going to get loaded only once.

In conclusion I would urge developers to be mindful of accessibility when creating CSS styles for web development projects. In fact quite the opposite is true.

However, of more importance is the affect this has on the accessibility of your website. If all styles are contained within externally linked style sheets people will be much more able to override the default presentation of elements on the page.

This is likely to make it easier for some visitors to your website to engage with the content contained within. Drill it in.

Skip to main content Home blog CSS Inline styles and why they are considered harmful for accessibility. I agree with Brian MacDonald The only moment I use inline CSS is for e-mailing like newsletters to say something. One instance it generating a random background URL on page load.

There are other cases though where you might want a CSS value generated on the fly. That's it for me. Otherwise, I use it in an external file. The other points here are still valid. I used to use inline styles when I initially made my pages, and then I would convert them to external style sheets. It was just easier to to use one file when making the page, I wouldn't use them when I published a site though. To answer your original question, the only time I have ever seen it and have it work is when using them with images.

Thanks for all the great responses. So I'm drawing the impression that whoever wrote the code for slacker. I wonder if GUI website making programs might do that too. Like Dreamweaver, etc. Richard Rakin ,. Posting to the forum is only allowed for members with active accounts.
