There are a few ways to break a line without using a tag. For that, we can use block-level elements.
Block-level elements start on a new line by default (if a CSS rule does not override the default behavior). Here, you can find how to make inline elements start on a new line.
In this snippet, we’ll use the following properties:
Let’s see how to break a line using the white-space property. This property specifies how the white space within an element must be handled. A white space can be a space sequence or a line break.
Create HTML
h1>W3Docs h1> div> Example Example div>
Add CSS
Use the text-align property set to “center” for the element.
Add color to .
Use the white-space property set to “pre” for the element.
body < text-align: center; > h1 < color: #000000; > div < white-space: pre; >
Example of breaking a line using the white-space property:
html> html> head> title>Title of the document title> style> body < text-align: center; > h1 < color: #000000; > div < white-space: pre; > style> head> body> h1>W3Docs h1> div> Example Example div> body> html>
Result
W3Docs
Next, we’ll show how to break a line with the display property. We need to set display: block to represent an element as a block element. In the following example, we set display: block to the element which is inside a element.
Example of breaking a line using the display property:
Also, you can use the carriage return character (\A) as content in pseudo-element.
It is possible to add a new line using ::before and ::after pseudo-elements.
Example of breaking a line using the ::after pseudo-element:
html> html> head> title>Title of the document title> style> .line:after < content: '\A'; white-space: pre; > style> head> body> h3> spanclass="line">This is the first line span> spanclass="secondary-label">second line span> h3> body> html>
HTML – Image Tag Tutorial» width=»600″ height=»400″/>
In HTML, you use the tag to add images to websites. It is an inline and empty element, which means that it doesn’t start on a new line and doesn’t take a closing tag (unlike the paragraph (
) tag, for instance).
The tag takes several attributes, of which src , height , width , and alt are the most important.
Knowing the ins and outs along with some best practices of the tag is crucial because images can negatively affect your site’s load time and SEO.
So in this tutorial, we will take a look at how to add images to websites using the tag, how to use its attributes, some best practices, and modern approaches to using .
Basic HTML Tag Syntax
Here’s the basic syntax for adding an tag to your HTML:
Now let’s talk about its attributes and how they work.
HTML Tag Attributes
The src Attribute
The src attribute signifies the image source. Without it, the tag itself wouldn’t be functional in the real world.
It indicates to the browser where to find the image. So it takes a relative path if the image is hosted locally, or an absolute URL if the image is hosted online.
The alt Attribute
The alt attribute specifies an alternative text for the image. This could be the text that shows during a network failure, for example. Or it could display something when the image source is wrongly specified, so users know what the image is about.
In the code snippet below, the image source is wrongly specified, showing you the role that the alt attribute plays:
This is the CSS that centers the image horizontally and vertically:
The width and height Attributes
You can use these attributes to specify a certain width and height for your images. With these attributes, you can resize the image down or up.
Ideally, though, you shouldn’t resize an image with these attributes. We’ll touch on this more under best practices.
HTML Tag Best Practices
Do not resize an image with the width and height attributes.
This is a bad practice because it can make the image appear distorted and can affect the quality.
Instead, you can optimize the image to your desired dimensions with photo editing software such as Photoshop.
In the code snippet below, I specify a width and height for the image – a bad practice:
The image looks like this:
Without using the width and height attributes, the image looks like this:
Name Your Images Appropriately
Naming images appropriately can help search engines understand what the image is about. For example, name an image ring-tailed-lemurs.webp instead of photo-1580855733764-084b90737008.webp . The latter is not enough for search engine optimization (SEO).
Reduce Image File Size
The image’s file size is crucial when it comes to page speed. A smaller image size (that preserves the image’s quality) reduces load time while larger images take forever to load.
There are several tools and various software that can help you do this. Some examples are imageOptim, jStrip, and PNGGauntet. And if you’re concerned about SEO, you’ll want to look into these – as page speed is an important ranking factor.
Host Images with a CDN
Imagine if a website is hosted in the United States but a user in Africa wants to accessed it. Assets such as images and icons would have to travel from The States to Africa, which in turn slows download time.
Using a CDN (Content Delivery Network) will allow the website’s images to be cached across several locations around the world. The CDN can then serve them from locations closest to the user, improving load time and providing a better user experience.
Cloudflare is a popular CDN that a lot of developers use to host their images.
Use Descriptive Alternative Text
Using descriptive alternative text helps search engines understand what the image is about. But it doesn’t end there – the alt text must also be relevant to the image.
Use the title Attribute to Show Tooltips
Just like the alt attribute, you can use the title attribute to show additional information about the image. Browsers display this as a tooltip when the user hovers over the image.
Tag Modern Approaches
There are various ways you can use the tag that are a bit more up to date and modern. Let’s look at some of them now.
Lazy Load Images
Lazy loading is a newish «load what is needed» concept. With lazy loading, the image is loaded only when the user scrolls to its viewport.
This is in contrast to eager loading, which loads every image immediately after the page is rendered by the browser.
To apply lazy loading, add the loading attribute to the tag and set the value to “lazy”.
Images are often quite high quality and large these days, but this can negatively impact user experience and SEO – hence the introduction of lazy loading.
Use the and Tags
Often, you might need to specify to the user the caption of an image. A lot of developers do this by placing a
tag right after the .
This might not be wrong, but it defies best practices and does not associate the caption with the image, so search engines won’t understand what it is.
Ring-tailed lemurs are social animals
Its is clear that there is no association between the image and the caption in the above example.
HTML5 introduced the and elements to help with this. You wrap the tag inside a element, and you specify a caption within the element.
This helps search engines associate the caption with the image, leading to better performance and SEO.
The snippets of code below and the screenshots show you an image with and without the and elements:
Ring-tailed lemures are social animals
You can see now that the image and the caption are beautifully associated.
Use the .webP Image Format
.webP is an image format created by Google. According to the creator, it’s an image format lower in size than its counterparts — JPG, JPEG, PNG, but with the same quality.
This format has been getting more and more widely accepted and is considered the nextgen image format for the web.
Conclusion
I hope this article helps you understand how the tag works in HTML so you can use it properly in your projects. If you do so, it’ll help improve your user experience and SEO.
img это строчный элемент, и поэтому к нему применяется свойство vertical-align. В большинстве браузерах это свойство по умолчанию — baseline .
.c-head img < border: 0px solid;
DTX: Если ставишь 0, то её не будет, как это остается но не видно, у меня её нет https://jsfiddle.net/27s9du83/1/
DTX: >> Вопрос, почему она возникает Потому что img — это inline элемент. У inline элементов есть межстрочное расстояние.
Скорее всего не помогает font: 13px sans-serif; просто баг отрисовки в браузере. Попробуй увеличить масштаб в браузере и в другом браузере открыть.
От того что ты меняешь размер шрифта у img отступ не измениться, если только размер не сделать 0. Для понимания, можешь img считать большой буквой, с стандартными параметрами он обладает теми же свойствами, там вроде vertical-align только отличается.
Хотя font: 13px sans-serif; может помочь если у тебя line-height: 13px;. Это опять же к строкам относиться.
я вот что то не совсем понял, причем тут междустрочные интервалы и подобное?? ведь там как и указано в данном ответе, border’ы проставлены!! или вы все таки не про те линии?
Тег предназначен для отображения на веб-странице изображений в графическом формате GIF, JPEG или PNG. Адрес файла с картинкой задаётся через атрибут src . Если необходимо, то рисунок можно сделать ссылкой на другой файл, поместив тег в контейнер . При этом вокруг изображения отображается рамка, которую можно убрать, добавив атрибут border=»0″ в тег .
Рисунки также могут применяться в качестве карт-изображений, когда картинка содержит активные области, выступающие в качестве ссылок. Такая карта по внешнему виду ничем не отличается от обычного изображения, но при этом оно может быть разбито на невидимые зоны разной формы, где каждая из областей служит ссылкой.
